Hello,
I am looking for a BIOS for Hercules/Guillemot 3D Prophet II GTS 32 MB, the one from VGA Legacy (https://www.vgamuseum.info/index.php/cpu/item … ia-geforce2-gts) does not work. Perhaps the card is damaged, but I would like to try again. The card is detected under Windows 98 and the wfflashe program detects it, so it seems to be a problem with the BIOS.

i dont have any hercules BIOSs but, one idea i have used recently is unload your BIOS from the card to a file in dos, using debug.exe, and then use that BIOS as virtual BIOS to boot up the 86box virtual machine. You can verify if the BIOS was good or not that way. i would start by checking if 86box supports that particular card first.

Unfortunately, the original bios is damaged and nothing can be done with it.
