Hey guys,

So I got this Voodoo 3 3000 from ebay. It had an old bios v1.00.01. I wanted to update it to V2.15.12. I downloaded 3dFXflash 2.14, booted to command prompt. Ran "Flash V3_300~1.rom" from the 3dfxflash directory (as the file name was too long) and this message came up: "Eeprom could not be written, A valid image should still exist in ROM"

Obviously now the bios is gone so I will have to slap in a PCI card and try again. I was wondering, why I got this message? It was the correct bios for my card. A voodoo 3 3000 AGP with SDRAM. I downloaded the 2.15.12 bios for the V3 3000 with SD RAM so I don't understand why it didn't work.

Any help would be great,

thanks guys.

Did you backup the original BIOS ? What size is it ?
What size is the image that you tried to flash ?

Also, what is the EEPROM brand and part number ?

See also Any benefit to upgrading the BIOS on a Voodoo3?

EDIT: If you tried flashing a 64KB BIOS image into a 32KB EEPROM, it might explain what happened .

Yeah the original is backed up but I tried to blind flash it and it was a nogo. I will just have to install a PCI card and do it that way. I think maybe I might have an OEM Voodoo 3 (it came from Greece) so when I get the PCI card I'll go through the list of bio's until one of them works.

Success!!!

So I ordered an ATI Rage 128 XL from ebay (Cheapest PCI card I could find). Its an original chip on a new PCB made in China. Unfortunately the card only works on 3.3v PCI slots and my ASUS P2B slots are 5V. I knew this was probably going to be an issue once I did some research and a guy on Youtube made a video about this! He also explained how he added a 3.3v regulator to the card and *ding* it works in a 5V PCI slot with this modification. So I cannibalized a 3.3v regulator from a spare SD card to IDE adaptor I had laying around and would most likely never use.

Once this was done, It worked. I flashed the Voodoo 3 3000 with bios 21512SD.rom someone on this forum posted a few years ago and it worked great!

Its nice when things work out!
