Hi Japamac,

Thank you. It doesn't look like that in fact it looks completly different. Is it possible to email you the pictures of it? Also it has a VGA and DVI and Svideo connections, how would I flash it to work in a Mac do you have steps for this?
Cheers,
Paul

Hi Japamac,

I going to asking you a stupid question but I'm new to this. I have an old PC which has a PCI and AGP slot. From the instruction to flash this card I understand I need to have a regular PCI video card to view what I'm doing. The Geforce card will go into the AGP slot. Now the stupid question the computer I have doesn't have a floppy drive is there another way to get to the command prompt? Then the files I need to do the flash how would I do it without a floppy drive?

Cheers,
Paul

Any of the AGP 6800 cards with 256 Meg of VRAM in either the GT or Ultra lines will flash fine for Mac.

The Ultra ones require some ROM device id surgery as Arti's ROMs were written for GT.

The BFG card linked in photos will be fine.

You will need a PC with DOS and NVFLash.exe.

Hi Folks,

I have run into a snag.

It Didn't work....

Any ideas? I followed this document to a tee..
http://themacelite.wikidot.com/nvidia-general-flashing

I tried
a:\>nvflash --index=0 -4 -5 -6 -j nvmac.rom
a:\>nvflash --index=0 -6 -j nvmac.rom

The PCI card I have is an Nvidia so for the index I orginally tried was 1 but it came back with an invalid display adaptor.

I have a G5 mac not sure why this isn't working I tried using the VGA and DVI ports same results. I don't need to tape the contacts since I have the G5 so I have ruled that out.
I did the nvflash --eraseeeprom as well and I'm using NVFLASH 5.77
Any ideas on what I'm doing wrong? do i need to do anything with the CWSDPMI. EXE file?

Thanks for you help.
