Hi.
I checked some of the download links on first page, and the file on dropbox doesn't exist anymore.
I guess that all of the files on dropbox aren't there, so where can I get those files?
Thanks.

You should find almost all stock Apple ROMs in TechPowerUp database.

Hi all looking for an EFI Bios for an 8800GT VBios 62.92.20.00.16 10DE/0611. If anyone has it in your archives that would be great trying to revive an old Mac Pro 3,1 and don't want to waste money on another video card. Thanks in advance.

You want the EFI64 version of 8800GT rom.
The tricky part is 8800GTs are hit or miss as to whether they have 64K eprom or 128K.
EVGA brand usually have 128K, other brands usually did not.

Hi, Rominator.
Is there any way to extract the efi gop (or how is it called) from the efi32 8800gt rom to insert in a 8400gs rom?

Yeah, I no longer remember how but it can happen. I did a bunch of G80 and G92 EFI roms and seem to recall it was pretty easy. Don't remember if you have to decompress the EFI. Good luck, but it can be done |

The card seems to be a G86 chip, I tried to ask in win-raid forum, where they use gopupd, but since yesterday I didn't get any answer. I understand that maybe I'm bothering you, but can't you help me a little bit at least telling me what software should and/or can I use to do the task? Thanks in advance. |

Ok, so I managed to get the compressed mac efi32 gop extracted from the 8800gt efi32 rom, and I merged it to the original 8400GS rom, but now it's too large for the eeprom chip: should I change the chip unsoldering the old one and soldering a newer one with more space?

Using GOPupd, I tried to merge the EFI32 gop from the 8800gt, extracted with GOPupd itself, with the original bios of a Palit GTS250 1Gb, g92 based, but it don't work on the Mac Pro 1,1/2,1 as it doesn't show the bootscreen.
Maybe I did something wrong?
Tha card works perfectly, on El Capitan, and under GPU-Z (on windows) it shows the "UEFI" support check.
What did you use, Rominator, can you try to remember or find back your past works, please?
It's very important to me.
Thanks.

just correct device id in header of EFI to GTS250
Where this gets messy is that G92 uses soft straps to change dev id, so in all likelihood could make card appear as 8800GT, I'm even recalling now that soft strap tricks depended on whether card was closer to 0x0602 or 0x0611
Yopu have to understand, this is a bunch of stuff for a $25 card
Needs 128K chip as well
And then DCB tables and last rom indicator fix
good luck

Yopu have to understand, this is a bunch of stuff for a $25 card I know, I'm sorry to bother you about this, but I need to use what we already have  Needs 128K chip as well The GTS 250 already have a 128K chip, that's why I tried. And then DCB tables and last rom indicator fix Now I'm lost @_@ good luck Thanks ^^; |
