SCSI on Windows 10 64-bit: Adaptec AHA-2940 (29xx) Ultra, AIC-7870 (78xx), or 29320LPE Ultra 320

When I first started playing with 68k macintosh systems around 1999/2000 (a Macintosh Plus) I connected an external SCSI drive to my Windows 98 system and was able to use an early version of Basilisk II with SCSI pass-through to format the hard drive.  Now 18 years later, SCSI is an obsolete technology, and in general is not supported under the latest versions of Windows and the the Macintosh OS, although I believe Linux still has support.

Luckily a skilled person on the internet has made 64-bit compatible drivers to support some of Adaptec’s cards under Windows 10 (sorry I’ve found nothing for the latest version of the Macintosh OS).   I’ve personally tested the Windows 10 driver for Adaptec AHA-29xx cards with an AHA 2940U PCI card.

I’m not sure how much longer using SCSI controllers will be supported, so if you don’t already have working SCSI devices I’d suggest you invest in one of the more modern solutions such as SCSI2SD for setting up your classic Macintosh instead of using this option.   But, if you’re like me, and do have a bunch of old hardware, it’s good to know we can still use it on our modern systems to setup our aging systems for at least a couple of more years.

Step 1: Select your driver

Step 2: Configure Windows 10 to let you install unsigned drivers

Updated 2019/03/13: Shane’s suggested method is now blocked by windows Secure Boot Policy… you can turn off the Secure Boot Policy, but the methods I found are more complex than the original method to do this… so I’ve reverted back.

Update 2018/12/31: Shane Cook (see comments) provided an easier way to install unsigned drivers.  I’ve updated this post with his suggested changes.

Figure 1: Choose an option
  1. Physically install your SCSI card in to your computer if you haven’t already
  2. Download either the AHA-29xx or AIC-78xx driver for your card if you haven’t already
  3. Unzip the zip file,
    1. there should be a folder called: AdaptecAic78xx
    2. the folder contains 3 files: djsvs.inf, djsvs.PNF, djsvs.sys
  4. Hold down your shift key and select windows -> power -> restart
  5. On the screen titled: Choose and option, select Troubleshoot (Figure 1)
  6. On the screen titled: Troubleshoot, select Advanced options
  7. On the screen titled: Advanced Options, select Startup Settings (you may have to select more options)
  8. On the screen titled: Startup Settings, select Restart
  9. After your computer restarts, on the screen titles Startup Settings, select Disable Driver signature enforcement (option 7 for me)
  10. Wait for you computer to finish restarting, you should now be able to install the driver for your card.
  11. Run Command Prompt as Administrator (added 2018/12/31)
  12. In the Command Prompt Window run: bcdedit.exe /set nointegritychecks ON (added 2018/12/31)

Step 3: Installing the Driver

Figure 2: SCSI Controller
  1. Open Window’s control panel
  2. On the window titled: Control Panel, Adjust your computers settings, choose Hardware and Sound
  3. On the window titled: Hardware and Sound, under the grouping Devices and Printers, choose Device Manager
  4. On the windows titled: Device Manager, you should see an Under device manager you should see a grouping Other devices -> SCSI Controller, select SCSI Controller (Figure 2)
  5. Right click on SCSI Controller, and select Update Driver
  6. On the window titled: Update Drivers, select Browse my computer for driver software
  7. Select the folder containing the driver you downloaded (Figure 3)
  8. Windows should ask you if you want to install the unsigned driver (Figure 4), select install this driver software anyway.
  9. Windows should install the driver (Figure 5)
  10. The proper name for your card should be listed in the Device Manager (Figure 6)
  11. Run Command Prompt as Administrator (added 2018/12/31)
  12. In the Command Prompt Window run: bcdedit.exe /set nointegritychecks OFF (added 2018/12/31)
  13. Turn off your computer
  14. Connect a SCSI device to your computer and reboot.   I tested with a Iomega Jaz 2GB drive. (Figure 7)
Figure 3: Browse to files
Figure 4: Install this driver software anyway
Figure 5: Driver Installed
Figure 6: Driver Listed
Figure 7: Drive Attached
 

Steps 4: Using a connected storage device

I’m assuming that you mainly want to get a SCSI device connected to your modern system because you want to setup an old hard drive, or removable drive for use with a 68k Macintosh System, or some other SCSI system from that era.

As I mentioned in my intro paragraph, I originally connected an external hard drive and used Basilisk II’s SCSI pass-through feature to setup the drive.  I haven’t been able to get SCSI pass-through working under Windows 10, so instead I now I attach the SCSI device/drive to my PC and then create a disk image to work with, then write the edited disk image back to the device/drive.

Step 5: Let me know in the comments if this worked (or not)

I’m not the creator of these drivers, so I can only vouch for cards they have been tested on that work.   Please comment to let me know what card you’ve used these with and did they or did they not work.

  1. Hi Steve,

    When I download your Unsigned driver for Adaptec AHA-29xx cards there is only and entry inside for the 78xx scsi cards. Am I missing something ?

    Regards

    • The creator of the driver modified the 78xx drivers, if you look in the .inf file you’ll see entries for the 29xx series of cards, e.g. the Adaptec AHA-2940AU PCI SCSI Controller, I’ve updated the blog entry with a note.

  2. Hello Steve,

    You can add the Adaptec AVA-2906 to the working cards list. I had 2940’s but no more, so I decide to try with the 2906. The setup included the PCI Adaptec 2906, a SCSI 50 pin ribbon cable and a 1.3GB SCSI MO internal drive. I followed your instructions and after rebooting the drive was online in Windows 10. Reading and writing was very good if not better than years ago. I loaded the 2940 drivers. I also can confirm SCSI still works on linux. We had a Workstation running Opensuse Tumbleweed that had two 300GB SCSI drives. That was less than 2 years ago. Next time I will try to mount one of the 300GB drives on Windows 10.

    Thanks for the great tutorial.

  3. Hi Steve

    I have an Adaptec 2940 PCI Card. I followed your instruction to the letter. Unfortunately, when I give the location of the djsvs.inf and the djsvs.sys files, Windows 10 (64 bit) tells me that it does not find any driver. Any idea what is wrong?

    • Hi Kurt, not sure. I’ll test this again later this weekend, hopefully nothing has been changed in Windows 10 that prevents the installation. is your Adaptec 2940 card listed under “Other Devices?” (step 3.4). Also when you downloaded the .zip file did it have all 3 files (I updated the blog entry to list them).

      • Hi Steve

        Thanks for prompt reply and for updating the blog. The Adaptec 2940 card is listed exactly like in your screenshot above, i.e. as “SCSI Controller” with the exclamation mark. All three downloaded and unzipped files are in my folder: djsvs.inf (18KB), djsvs.PNF (8KB) and djsvs.sys (87 KB).

        I assume that there is no aspi required under Windows 10? Please let me know if I can assist with any additional information.

        • Hi Steve

          One more thing: the system tells me that it could “not find any drivers for this device” although I pointed it to the folder with the drivers. It appears to me that the system refuses the “unsigned drivers” although I went through the procedure in your step 2.

          • Just tried with a clean install of Windows 10 build 1803 and was able to install the driver for my 2940AU card. It could be you have a version of the 2940 series that isn’t supported, or something else on you system is blocking the install. I’ve added some more screen shots to show the later steps so you can confirm how far you get.

  4. Hi, I report that Your solution is working. My configuration:
    IBM Thinkstation S20, Win 10 Pro 64bit (1703), Adaptec AHA-2940UW PCI SCSI adapter. Thank You.

  5. Hi Steve,

    thanks for putting together that information!

    I chose the AdaptecAic78xx_for_AHA_29xx.zip file and installation of the driver for my old Adaptec AHA-2940AU on Win 10 pro / 64-Bit went smoothly just as described. Next I’ll hook up my Fujitsu MO-Drive…

    Regards

  6. Hi Steve

    I’m back just to confirm that your solution is working. My AHA-2940U2W has another chip set, and I could not solve the problem. It uses the driver aic78u2.sys (instead of djsvs.sys). So I bought an AHA-2940/2940U from Ebay, i.e. I circumvented the Problem. With the new card, the patch is working.

    Thanks

    P.S. If somebody comes up with a solution for the AHA-2940U2W, I am still interested.

    • Can you provide more detail? E.g. what card did you try it with, did you have any other SCSI cards etc? Any additional information you can provide would be helpful so that others can avoid the issue.

  7. It worked as described with an Asrock H81 board PCI AHA-2940UW. After the driver was installed my DDS tape drive was listed as a cassette drive at the top of the device list. If updating the driver does not work try installing the driver manually by right clicking on the file “djsvs.inf” to install it.
    Thanks. I am backing up with tape and not accidently wiping out my files again !!!.

  8. I followed the instructions and it worked great to install my Adaptec scsi card (AHA-2940) but windows 10 can’t (or won’t recognize my HP Scanjet 4C). Any suggestions from anyone?

  9. The same case reported by Al. I followed the instructions and it worked great to install my Adaptec scsi card (AHA-2940) but windows 10 can’t (or won’t recognize my HP Scanjet 4C). I tried with VueScan x64 but it is not working very well because it identifies the scanner as HP Scanjet 6100, it seems that an update has to be done. Did Al give you feedback?

    • I wish I could help more, but I mainly wanted to get this working so I could connect old storage devices, most of those don’t need extra drivers. You best bet would be to contact VueScan to see if they could help.
      According to their website it’s supported. https://www.hamrick.com/vuescan/hp_scanjet_4c.html#technical-information
      To clarify, I’ve never used VueScan, or tried to use a SCSI scanner in at-least a decade.
      If you do get this working feel free to post here so others can benefit from what you figure out.

  10. Hi this looks really interesting and looks like it might solve my problem of connecting a Nikon Coolscan III scanner to my computer running Windows 10, however I noticed the comment about storage, should it work for the scanner? Thank you

    • Hi Guy, the driver posted here should let your computer see your SCSI card. But you’d likely still need a driver from VueScan to actually use the scanner. At least that’s how it was in the old days. One driver to activate the card, and a second driver to activate the device attached to the card (if it’s anything other than a storage device)

  11. Installed the driver today. Quick and simple to do following your instructions. Works perfectly with my AHA 2940/2940U card and my Nikon Coolscan III scanner. Vuescan is essential for the scanner driver. For film and slide scanning you need the Professional Edition. Supported scanners can be checked at http://www.hamrick.com. A free trial version can be downloaded to check whether it works with a particular scanner. If the web site says a scannner is supported but it isn’t working properly contact Ed Hamrick via Support/Contact us on the web site. He is very good at responding.

  12. I managed to buy a new ‘Adaptec 29320LPE PCI-E 1x U320 SCSI Card’ from Ebay.
    Windows 7 x64 drivers were available here:
    https://storage.microsemi.com/en-us/support/scsi/u320/asc-29320lpe/

    Despite being signed got the error “the publisher of an authenticode(tm) signed catalog was not established as trusted”. Why make this so dam complicated? After a bit more looking, I see you need to run command prompt as administrator and type

    bcdedit.exe /set nointegritychecks
    This disables ALL driver checks, so be careful with future drivers.

    Driver would then install. Adaptec SCSI Card 29320LPE – Ultra320 SCSI.
    Now I just need to find an external a SCSI lead that will fit my SCSI film scanner…..

    To enable driver checks, enable again with
    bcdedit.exe /set nointegritychecks off

    Hope this helps.

  13. Well, all this does is reinforce my 30+ years of disdain for Microsoft… /set doesn’t have a nointegritychecks command. I even tried cut-n-paste from Shane’s post above…
    ————————-
    Administrator: Command Prompt
    Microsoft Windows [Version 10.0.17134.590]
    (c) 2018 Microsoft Corporation. All rights reserved.

    C:\WINDOWS\system32>bcdedit.exe /set nointegritychecks
    The set command specified is not valid.
    Run “bcdedit /?” for command line assistance.
    The parameter is incorrect.

    C:\WINDOWS\system32>

    Someone else mentioned having to boot from the installation disk to get this to work. I guess I’ll try that…

  14. So does this mean I’m done, with nowhere else to go? When I select “View – devices by connection”, I can see the drive, correct size and part number, etc. However it doesn’t show up even as an unformatted disk in the drive list in File Explorer. It’s like it is nowhere, yet I can see everything about it in the Device Manager…

    • Hi Keith, have you tried initializing the drive through Windows Disk Management application?
      Control Panel -> System and Security -> Administrative Tools -> Computer Management -> Storage -> Disk Management?
      I’ve used this method mainly for connecting and formatting removable media, and emulated drives (e.g. SCSI2SD).

      For bcdedit.exe /set nointegritychecks two things:
      I had a typo, it should have been bcdedit.exe /set nointegritychecks ON, I’ve updated my blog.
      Also Windows now blocks this as part of it’s default “secure boot policy”. I’ve found a few ways to turn that off, but it makes this method, way, way more complicated.
      So for now I’ve reverted back to the original method which still works.

  15. I have followed your instructions above to install an Adaptec SCSI controller AVA 2904 to interface an old Canoscan 2700F under Windows10. I used ‘Unsigned driver for Adaptec AHA-29xx cards ‘ from above and this worked effortlessly. Thank you very much.

  16. Driver and your instructions did the trick for an Adaptec 2930 and Syquest Syjet. Ahh…and now for easier file transfer between PC and Atari Falcon. Thanks so much!

  17. Thanks very much for this! I got my old Minolta Dimage Scan Elite F-2900 to scan again after these drivers worked for my AHA-2930U SCSI card. I use VueScan software and it recognised the scanner without a glitch.

  18. Hi,
    Thank you so much for this driver fix. Using it I’ve brought an ancient Adaptec AVA-2904E/canon PCI card back to life and it’s working fine with a canon FS7210 film scanner which was otherwise destined for the scrapheap. I’m running Windows 10 Pro version 1903 OS Build 18362.207

  19. I am hoping to get my Adaptec 2940UW card installed along with my SCSI Plextor 8/20 CD writer and Plextor 40 CDrom which I’ve used for years on Windows XP. I now am at version 1809 on Windows 10 Pro. My question, which hasn’t been addressed that I can see, is whether I need to intall an ASPI layer with Windows 10? I am running software on Windows 10 which I had running on Windows XP which is compatible with the Plextor drives. Thank you

    • Hi Delbert,
      Yes, I believe you need an ASPI layer, I did some hunting about a year ago when I tracked down these drivers, I didn’t have any luck.
      If you find something let me know.

      • I ran a check of my Windows 64 bit system using ASPICHK.exe and it reported I am running wnaspi32.dll version 4.60 which is located in my syswow64 folder of my windows directory. I assume this was installed when I installed Exact Audio Copy. I have been using EAC version V.095 prebeta which is a pretty old version, but have not experienced any problems ripping audio CDs to Windows 10. I think this is the only ASPI file required because ASPI32.sys is a 32 bit file, WOWpost.exe is required only for 16 bit programs and ASPI32.dll is also only necessary on a 32 bit system. I’m going to proceed with the tutorial you’ve provided, but have decided to use an Adaptec AVA-2906 card instead of the 2940UW. The AVA-2906 card has an internal 50 pin connector and doesn’t come with the bios as the 2940UW. Got my fingers crossed

  20. Well, today, I set out to install my Adaptec 2940 UW card or my Adaptec AVA 2903 card in my computer to get this thing going. I was stumped from the beginning. Neither card could be inserted into the PCI Express slots of my Gigabyte Z370P motherboard thereby thwarting my well planned intentions. There’s always a hurdle!! So, it appears lacking a PCI slot, I am out of luck on this adventure……..

  21. Hello.
    Adaptec AHA 2940 UW works with Windows 10 64-bit, Professional, 1903/ newest updates.
    Thank you very much for the installation information and the driver.
    Greetings
    Frank

  22. Is there any way you can note the connector type on the different Win10 compatible cards you have noted?

    I am in need of a SCSI card that is has a connector for a High Density DB50 clip type cable to interface with an old Canon Scanner.

    • My AHA-2940U has a 50pin connector. The 29320LPE has a 68-pin VHDCI connector. The specs of these cards are all on Adpatec’s site including the connector types under the product specifications tab.

  23. My previously retired Adaptec AHA-2930U PCI SCSI card is working very well with this downloaded driver. Install was smooth and painless. Fantastic and thank you!

  24. Ref. your internet page:
    http://www.savagetaylor.com/2018/02/11/scsi-on-windows-10-adaptec-aha-2940-adaptec-29xx-ultra-or-aic-7870-adaptec-78xx/
    Hello, sorry for the silly question of a Windows 10 beginner. In your mentioned article you say in Step 2, item 4: “Hold down your shift key and select windows -> power -> restart”. Which keys do you mean (the special windows key or somewhat else)? Unfortunately, I am not able to end up with the blue window “Choose an option”.

    • Hi Ronald, whenever you see the word “select” in my notes I’m referring to a icon/menu item on your screen. In this case I’m referring to the windows icon that is tyipcally in the bottom left corner of your screen. However, you should also be able to press the windows key, select power, and “while holding down the shift key” select restart.

  25. Hello there…
    Thanks. My ole Nikon LS 2000 scanner now works on windows 10 64bit on a adaptec aha-2904
    Greetings from Denmark
    Ole

  26. AHA2940 with Nikon Coolscan III slide/negative scanner and Umax Astra 1220S A4 flatbed.
    Worked a treat on Win10-64.
    Many thanks.
    Martin.

  27. I successfully got the Adaptec 29320LPE PCI Card working in Windows 2016 by getting the Windows 2008 x64 drivers from this site: https://drivers.eu/SCSI/ADAPTEC/29320LPE
    Did the following steps-
    Open Device Manager
    Select SCSI Controller from the ‘Other’ Device in Device Manager
    Select ‘Update Driver Software’
    Select ‘Browse my computer for driver software’
    Select ‘Let me pick from a list of device drivers on my computer’
    Navigate to directory of extracted drivers
    Select ADPU320.INF
    Select Adaptec SCSI Card 29320LPE – Ultra320 SCSI
    NOTE: There are other versions of the drivers present on the site, I specifically used v7.0.0.11 successfully!
    Hope this helps others if needed!

  28. I had great success using the above information after tweaking the install a bit. After setting the above bcdedit parameters the drivers still would not load, I then used the GUI to disable signature checking:
    1. Click START, type Recovery OPTION, not Recovery Control Panel in the command box, and select same.
    2. Click ADVANCED STARTUP, let the system reboot, then select TROUBLESHOOT press enter.
    3. After boot, click on ADVANCED OPTIONS>STARTUP SETTINGS, and wait for reboot.
    4. Select DISABLE DRIVER SIGNATURE ENFORCEMENT (option 7 for me) from the list. When the system has rebooted yet again, log in and go to device manager and load the above drivers for your card.
    This was successful for me for the following Adaptec SCSI cards: AHA2944, ASC29320,AHA2940W. What did not work were Adaptec ASC29160,ASC19160, and AHA2940U2.

    On a side note, I was able to also load the following LSI (Symbios) Logic SCSI Drivers: LSI22915 (53C1010-66 chipset), LSI22802 (53C986 chip set) and IBM FRU 40H6595 with LSI chipset 53C875.
    You can find the drivers for the LSI cards on-line. Not sure I can post them here as I didn’t write them and don’t know who did. They also worked for Win 7, and have been modified from the original LSI drivers.

    WOW, I just saved a bunch of electronic junk from the scrap heap, and can now up grade to windows 10, and my disk arrays and LTO tape library drives will continue to work.

  29. I would like to get a confirmation that an Adaptec card such as the 2940U can still be installed on a Motherboard with PCI-Expres slots, such as the Asus Z87-Pro for example ??

    Thank you,
    P.S.: I am going to order this card to connect a Canon FS4000 scanner to my W10-64 PC…

  30. Works now with an adaptec card AVA 2903B + Epson Perfection 1200S + Vuescan from Hamrick software under win 10. I installed the driver “Unsigned driver for Adaptec AHA-29xx cards “. After restart with switched on scanner the scanner works well.

  31. I am having issues installing an adaptec aha-2940u/uw card into my windows 10 x64 pc. Windows does not detect it as a scsi card at all, and when I try to install the 29xx drivers on the detected device, it adds the microsoft storage spaces device, and the adaptec drivers is installed with an error.

    • Hi GB, is that the same as the AHA-2940U2W? That was previously reported by Kurt as not working because it used a different chipset than the rest of the AHA-2940 cards. I’d suggest looking at getting one of the cards that has been tested by someone else as working.

      • It is printed on the card as AHA-2940W/AHA-2940UW, there is a sticker on the adaptec chip that shows AHA-2940UW/DELL2. I finally figured out what was going on. The first few times I booted the computer, the SCSI card was not being recognized in BIOS. After a few shut downs, it finally started showing the Adaptec pre-boot setup, so I went into the menu, and enabled the PnP option. It then showed up in windows and your driver installed ok. I am able to read MO disks. (My previous troubleshooting led me to do a fresh windows 7 install, which is when the card started showing the pre-boot menu, it installed ok in Win 7. After that I did a fresh install of Win 10, and it is working in that, too!) Thank you very much for this post and your response!

  32. Hi, I tried your Solution with Windows 7 operating system and a Adaptec AHA-2940 Ultra. It works very well, I use the card with some old scanners, a Canon FS4000US, Nikon COllscan II and Imacon Flextight. I recommend Vuescan for Scanning, Silverfast SE could not be started, the software doesn´t find the scanners, although the scanners are shown in the device manager.
    Thank you very much for your page with this information.

  33. I have received the SCSI cable, but I am still waiting for the Adaptec 29320 board: because of the Chinese new year, it is very difficult to get a shipping tracking update…
    Meantime, I thought about another way (maybe more complex but valuable in the long run): changing the original USB-1 integrated circuit by a new USB-2 integrated circuit (Ok, we would have to solder/desolder, but…)
    Does any of you have already opened the Canon FS4000 to read the reference number of the original USB-1 integrated circuit ?

  34. Hi,
    I have finally received my Adaptec 29320-LPE SCSI card, and I have successfully installed it on W10-64 with the (Microsoft certified) W7-64bits drivers.
    The board is OK in the Windows Device Manager and boots properly.
    But the problem is that it does NOT detect my Canon FS4000 scanner : so I can’t go further !
    The scanner is setup on SCSI channel 2 with Termination ON.
    Do you have any idea ?
    Thank you very much

      • I confirm that the Adaptec 29320-LPE card works perfectly under W10-64 bits v1903, with the W7 signed driver (as explained by Steve).

        In order to get the Canon FS4000 scanner recognized by the Adaptec SCSI board, the FS4000 should be configured with “Termination OFF”: this is achieved by selecting the appropriate position of a rotary switch located under the scanner. If you select an SCSI ID with “Termination ON”, the scanner will not be detected by the Adaptec board.
        The settings of the Adaptec 29320-LPE should all be let “by defaut”.

        I use Vuescan and it perfectly detects the scanner and communicate with it: for example it can eject the film holder…
        Unfortunately, my scanner does not work (it does not scan anything) but this seems to be a problem at the scanner level, because it is also faulty when connected with USB : so the problem should not have any link with the SCSI board.
        Hamrick from Vuescan currently studies the “Vuescan.log” files (both the log when connected with SCSI and the log when connected with USB) to be sure that the problem does not come from Vuescan.

        By the way, if one of you knows how to fix a FS4000, please tell me !!! Maybe a faulty capacitor due to the age ?
        Thank you for any help you could provide me with (regarding the hardware scanner problem)…

    • Hi René, sorry it seems to have a different chipset. See the comment from Kurt: “My AHA-2940U2W has another chip set, and I could not solve the problem. It uses the driver aic78u2.sys (instead of djsvs.sys)”

  35. Hi Steve,

    I have tried to get my AHA-2930CU/2930U working on Win 7 and Win 10 x64 as the old desktop running XP finally bit the dust. I can get the drivers installed but it lists the device with an ! beside it and says “This device cannot start (code 10)”. Rebooting doesn’t seem to resolve the issue either.

    Any ideas?

    • I’m not sure, you followed the steps exactly? The old computer I used to test my 2940 card with no longer works (failed power supply), so I’m not sure when I’ll be able to test this again. Hopefully windows hasn’t changed something that prevents the driver from working. My 29320LPE PCIe still works.

  36. FYI
    Recognised AHA-2940UW with Windows 7 x64, recognised Internally connected Panasonic LF-D101 drive as a CD Drive & Externally connected Epson scanner, but unable to communicate with the Scanner using epson S/W or TWAIN driver(which is prob. 32-bit) via gimp.

  37. I’m trying to use a Adaptec AVA-2902BE and for some reason when I physically install the card the computer turns on but I don’t get any signal from the GPU when the card is installed. When I remove the card the GPU functions fine. Anyone have any possible solutions?

  38. Windows tells me it can’t find a driver in that folder, despite it being there….
    trying to get an Adaptec AIC-7850 going…

    • Hi Scott, I haven’t personally tested the 78xx drivers, only the 24xx and ultra 320. I’m going to assume you’ve gone through all the steps so windows can find and install an unsigned driver? If so, I’m not sure why it’s not working. Unfortunately you seem to be one of the first people to try it.

      • Odd, I just tested the 320 driver again on my windows 10 pc (did a clean install a few months ago). I downloaded the driver, ran the .exe and it placed the drivers in c:\adaptec\scsi.
        I was able to select the card in device manager and update/install the driver (selecting c:\adaptec\scsi as the source folder), and Windows 10 recognized the card.

  39. Hello Steve, I came across this blog and could succesfully install the driver for my 2940au. I see in your pictures you have a jazz drive attached. Mine is a 1GB version but is not detected. I have Win10-1903 running. Any idea?

  40. I experimented with the cabling. Connected the internal Jaz drive via the back connector and it works! I will check my cables. Thanks for a working solution.

  41. Just upgraded my PC to Win 10-64 and used the AdaptecAic78xx_for_AHA_29xx driver with an Adaptec AVA-2903B and Nikon CoolScan III with VueScan. Thanks so much!

  42. You guys are great. Got my Minolta Dimage Multi scanner working again on Windows 10.
    SCSI card is AHA-2940AU.

    Thanks!

  43. Found the windows 2008 r2 drivers for adaptec 39160 scsi ultrawide card I have. Worked beautifully under Windows 10 using this method.

  44. Thanks a lot! I got my MO Drive Fujitsu M2513 up and running with WIndows 10 64-Bit on an AHA-2940AU Controller. Found some old disks with data from 2003 – all is safe!
    Great job, thank you for publishing and providing!
