It's the Adaptec AHA-2490. I haven't changed the firmware on this card. I am using a HP 6300 scanner with the card, connected through SCSI. (The usb port on it is broken and has not worked for years)
I was previously Windows XP x86, and now I'm using Windows 7 x64. I did a clean install.
There are no x64 drivers for this card full-stop.
I was trying the AIC-7870 driver because i read somewhere its compatible with the 2940, but I can't find it in the windows 7 driver bank either.
I read somewhere else that the xp 64 driver would be accepted but I can't find any, after a long time searching.
Is there a way to force the windows xp 32-bit drivers to load and hopefully work?
Edit: I also have tried selecting that driver, but it doesnt come up in my list of drivers when i follow those steps.
