Doesn't speedsys do this?

DOS versions of Aida or Astra?

Speedsys just says "Generic VGA".
Good idea, will try Aida.

Is it PCI or ISA? If its PCI it has a device and vendor IDs, but for ISA cards I don't think there is a standard way of detecting. Dumping the video BIOS and looking for any strings can be an option. Other than that, if you put it on a monitor that syncs fast enough, doesn't it say anything on the video "POST" screen? (the one before the actual BIOS stats doing stuff, normally just displaying the graphics card's copyright information)

Try looking in the video BIOS with debug.exe. Just type D C000:0 and keep pressing enter, usually you can find some text strings in there to identify the card.

I should type faster next time.

AIDA helped me:

Thank you 😀

HWiNFO (http://www.hwinfo.com/) has a DOS version as well.
