Voodoo 4 mod from 32 to 64 MB RAM: finaly, succes!

Before:

After:

Post-screen (bootscreen):

Big thanks for Hanksemenec and Mikulaish, this project could never finalized whithout them helping and supporting. Mikulaish provided the extra 32 Mb RAM chips and the BIOS-hacking; Hanksemenec provided tech-info's; I just provided the Voodoo 4 4500 AGP and soldered the memory. After flashing to hacked BIOS I got myself to be the proud owner of this long waited 64Mb RAM single chip VSA 100 video card!
The card is perfect working; all 64Mb RAM are being used. I will post more details as soon as I can spare some free time (I am at work right now...).

I would just like to add that changing the strapping resistor configuration didn't help recognising the extra memory. The only modification needed is in the bios (stricly my opinion for now, don't shoot me if i'm wrong). There is a bit that defines the no. of memory chipsets. It has to be changed from 0 to 1, meaning 2 chipsets instead of 1.

I don't even own a v4 . But to be certain of the bios, yours, TM30, would really help. Could you dump and send it to me, please?
