Yes, also happens with the PCI Voodoo3 1000. I didn't see a PCI version of the Velocity.

I suspect they gutted out the VRAM detection from the BIOS but kept the 4 MB and 8 MB strings, since these two cards came with 16 MB soldered memory.

There are 8mb versions of the V3 1000 probably for OEMs.

There's a collection of BIOS'es here: https://3dfxbios.cl-rahden.de/index.php?title=Voodoo3. But no Voodoo 3 1000 PCI BIOS.

OK, did a test binary comparison of an AGP and a PCI BIOS of the same Voodoo card and BIOS version, and aside from a random string, they're 100% identical, so I conclude the AGP and PCI BIOS'es are fully interchangeable.
