CaptainNemo Posted September 18, 2008 Share Posted September 18, 2008 Hi guys, since I've got my Mac Pro I'm very with that, but - I have 2x 22" Displays and there are 2x 19" TFT unused. I've a GeForce 7600GS (passive) and I would love to flash it for my Mac Pro. I've a PC @home, so it's no problem to flash it, but I'm unsure how to do it and where to get the sources. Maybe this works: Flash Tool: http://themacelite.wikidot.com/nvflash-basics And the "GT" (it's a GS card!): http://campahunta.free.fr/Downloads/ROMs/7...MAC_EFI.rom.zip Anyone has tried it or knows a source for the 7600GS? Thanks in advance!!! Nemo Link to comment https://www.insanelymac.com/forum/topic/126729-flashing-geforce7600gs-for-mac-pro/ Share on other sites More sharing options...
CaptainNemo Posted September 18, 2008 Author Share Posted September 18, 2008 Hi guys, I tried it, but I can't flash the GS with the GT firmware. I get errors, what won't happen, if I restore the original backup-firmware. So... looks like I NEED a GS ROM-file Ciao Nemo Link to comment https://www.insanelymac.com/forum/topic/126729-flashing-geforce7600gs-for-mac-pro/#findComment-896300 Share on other sites More sharing options...
atzero. Posted September 18, 2008 Share Posted September 18, 2008 Found a site that had a bunch of ATI files, but no luck on Nvidia... I know for a fact that it has to be the exact file for the exact videocard, otherwise it doesn't work.

CaptainNemo Posted September 18, 2008 Author Share Posted September 18, 2008 Ok - it's a BAD idea to install the nvinject.kext :/ My Mac Pro starts into Kernel Panic with this... sssssssssssssshiiiiit!

CaptainNemo Posted September 19, 2008 Author Share Posted September 19, 2008 Hey guys, so... here's the solution if you had successfully killed your OS X on your "real" Mac Boot with pressed Command + S keys to the Single User Mode. Type /sbin/mount -uw / Type cd /System/Library/Extensions Remove the folder you used to mess up your sys. In my case it was nvinject.kext. Type rm -rf NVinkject.kext Type reboot and you should be able to login into your regular sys again Meanwhile - with still no luck getting the PC card working, I looked around for a cheap "Mac Pro" Ready graphiccard. There is a not that expensive GeForce 7300 GT, available for aroun 100 Euro. BUT - because I own a 2008 Mac Pro, it won't work. (Hey Apple - what kind of {censored} is that?!) So... after all, I would appreciate if someone has a GeForce 7600 GS 256MB ROM file. I think the card is a "colorware" or something similar to this name...

Reveeen Posted September 19, 2008 Share Posted September 19, 2008 Old guy scratches head............... The way I see it you have two choices: 1) you buy a card specifically to flash for your Mac (the EXACT card matching the .rom files available). 2) you follow the directions: http://themacelite.wikidot.com/nv-rom and after a LOT of trial and error (and learning, we must not forget the learning process) you end up with a working card. Yes it sucks. Link to comment https://www.insanelymac.com/forum/topic/126729-flashing-geforce7600gs-for-mac-pro/#findComment-897025 Share on other sites More sharing options...
BlackCH Posted September 19, 2008 Share Posted September 19, 2008 7600GS & 7600GT are not the same. The GT rom wont work on the GS. Your best choice is to get a 7600GT (but it has to have a 128kb rom chip in order to flash the EFI rom on it)....

CaptainNemo Posted September 21, 2008 Author Share Posted September 21, 2008 Hi guys, thanks for your replies. Meanwhile I've found the detailed information of my card, shown here. @reveen: I already started with this, but in the end I dunno where to get all these information (Option 2) To buy a new card.. well - if I would really buy a new card, I would directly get a GeForce 8800GT (like my 1st slot's one) from Apple. But in my mind it's damn too expensive.

Reveeen Posted September 21, 2008 Share Posted September 21, 2008 I already started with this, but in the end I dunno where to get all these information On a PC, you "dump" the original card's bios to the desktop (retaining a safe copy on the floppy you used for flashing), you would follow the instructions to turn it into a Mac bios. What I did was use a card there already a Mac bios for (FX5200) then I compared the two (the original PC bios, and the Mac bios, to see the areas they were talking about. Once I saw the differences, (and the stuff that was the same), and with the instructions, I felt confident I could "make" a Mac bios. At that point I ran out of time, and simply broke down, buying a supported card. It is possible, and I might get back to it this winter (snow seems to come in 2 foot amounts where I live), but when the weather is nice it is best to take advantage of it.

CaptainNemo Posted September 23, 2008 Author Share Posted September 23, 2008 Hi BlackCH, ok - so finally I give up with the GeForce 7600GS I already own. I will buy a 7600GT. I searched on eBay and tried to get information about the ROM size, but I can't find it anywhere :/ What I've found: Installed Memory: 256 MB Memory-Tech: GDDR3 SDRAM Memory bandwidth: 128 Bit This is a 7600GT "Point of View" - on the manufactures site I can't find more information. Do you have a hint for a good card? (Or another one which is 100% working and where ROMs exist for ) Nemo EDIT: Found a GeForce 8800GT with G92 Chip and 512MB RAM - and a tutorial for this on [url="http://forums.macrumors.com/showthread.php?t=434092&page=18[/url] So... I will do it! Link to comment https://www.insanelymac.com/forum/topic/126729-flashing-geforce7600gs-for-mac-pro/#findComment-902464 Share on other sites More sharing options...

I will do it! Is almost impossible to know the size of the rom chip until you have the card in your hands. That info doesnt comes on the regular hardware specs. Also there's no much information about how to reduce an EFI rom (which will be different than an old PPC rom I guess)... So is kind of a lotery, you see. You only can win if you gamble BTW I dont thing that method with the 8800GT will work on a real mac either. That is meant for a hackintosh and AFAIK efi strings are no good on Macs.... You wont be able to boot as your mac wont be able to 'see' the card ('cos it has a PC rom) Link to comment https://www.insanelymac.com/forum/topic/126729-flashing-geforce7600gs-for-mac-pro/#findComment-902542 Share on other sites More sharing options...
CaptainNemo Posted September 23, 2008 Author Share Posted September 23, 2008 Yes you're right but I searched and found this http://forums.macrumors.com/showthread.php...092&page=18 So hopefully I can put my Mac card (8800GT, too) into my PC, get a backup of the ROM, put the new card in, backup & falsh the mac card's ROM and it works. As I said: Hopefully Do you have a hint how to get this information (ROM-size) in OS X?

BlackCH Posted September 23, 2008 Share Posted September 23, 2008 Looks good. A way to know the size of the eprom basically is doing a rom dump and see how big is the file you get.... I guess you will need a PC to do the dump/re-flash... but by reading on the link seem there are good chances for this to work... Good luck!

CaptainNemo Posted September 23, 2008 Author Share Posted September 23, 2008 Well - the problem was, that I need a Powercable for mini 6pin PCIe onboard to PCIe 6pin @the card and I was unable to find it, so I canceled the order :/ Well... I think I should order the "original" Mac card... :/ Link to comment https://www.insanelymac.com/forum/topic/126729-flashing-geforce7600gs-for-mac-pro/#findComment-902999 Share on other sites More sharing options...
CaptainNemo Posted September 26, 2008 Author Share Posted September 26, 2008 Hi guys, I just want to give a feedback. I gave up and bought an ATI 2600 XT (256MB) 2x DVI-DualLink today for my 3rd & 4th TFT. Works great and costs 99 Euro.
