How to get Adaptec's latest ASPI update (V4.57) without having any Adaptec software or hardware? (thanks to Nicholas)

For the program to work perfect it seems you need the newest wnaspi32.dll you can get. Well I wanted the newest version. So I downloaded the upgrade ASPI32.EXE from http://www.adaptec.com/support/files/upgrades.html#ezscsi. Unfortunately, I have no Adaptec SCSI devices or programs, so the upgrade would not install...and you can't buy the upgrade from Adaptec. I have no need for any SCSI controllers or any of their programs (I'd much rather buy from the shareware market and not feed big business). So I improvised. This is what I did:

• I opened the Control Panel in Windows
• I opened Add New Hardware
• When it asked if I wanted Windows to search for the new hardware? I selected No.
• Then it asked what type of hardware did I want to install.
• I selected SCSI controllers.
• Then I selected a manufactures. I chose Adaptec
• Then I selected a model. I selected the "Adaptec AHA-150X/1510/152X/AIC-6X60 SCSI Host Adapter (Any of the non-Plug and Play cards will work for this task)
• So I installed the driver
• Then I restarted, and the controller was disabled in the Device Manager (obviously because it wasn't there)
• So I enabled it.
• Then restarted again.
• Now I have a Adaptec product installed on my machine.
• So I tried installing the ASPI upgrade again.
• And it worked.
• I have an updated version of ASPI (and the CD-DA Extractor works PERFECTLY)

Adaptec ASPI drivers under Windows 95 and Windows 98

How to recover the original 'wnaspi32.dll' from the Windows 95 CD-ROM:

• Open a DOS window
• Load your Windows 95/98 CD in the CD-ROM drive
• Go to the 'WIN95' or 'WIN98' directory on the Windows 95/98 CD
• Enter this command (WIN98): 'extract /y /a /e /l <tempdir> win98_22.cab wnaspi32.dll
  Or this command (WIN95): 'extract /y /a /e /l <tempdir> win95_02.cab wnaspi32.dll
  Where <tempdir> is a temporary directory on your harddisk (like: c:\windows\temp)
• Copy the wnaspi32.dll file from the <tempdir> directory to the 'windows\system' directory. If the system asks you to overwrite the existing file then answer 'yes'.
• Reboot the system

If you have Adaptec SCSI Adapter or Adaptec's software like EZ-SCSI, Easy CD-Pro, DirectCD, Easy CD Creator, etc. You can download the latest ASPI drivers from the Adaptec's WWW-site.
