Hi-

Welcome to Discussions!

I the card looks like This then it is a Mac edition and is plug and play.
If it doesn't look like that, then it must be flashed to Mac ROM (using a PC) before use in a Mac.

Hi-

I am sure that it is a PC version just from the port description.

If it has fancy graphics on the fan cover, then that seals the deal.

Here are instructions:

Most PC flashing tools I've seen have saving the present ROM as an option.

do you know how I can back up the PC Rom in case the Mac flash fails?

C:\NVFLASH\nvflash --save BACKUP.ROM
which will dump the ROM to file BACKUP.ROM

Under "How to Mod your own ROM"

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

Hi,

Here are some pictures of the card I'm going to buy. From the videos I have seen this card looks nothing like it. Will it still flash?

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.
