I’m back and more informal than ever. It’s been a long time since I’ve made a post on this site, only because I haven’t had time nor the energy to upgrade my hackintosh, not that I gave up on OSx86. Also not to mention this is no longer my English Project here at Georgia Tech, rather just a hobby now so I devote time as I have it — Like now in psychology 1101 class (endless time here, rather time seems to halt in this room, it should be allotted for quantum physics 1101 instead!). Lion has been out and I absolutely Love it on my macbook. Now I want it on my hackintosh, but it has been impossible lately. I think I have found the culprit…..
….I recall what I stated earlier, I hereby deem ATI 5770 (ending in …ZNFC) no longer the supposedly “most compatible video card” for the hackintosh community. Love this card, but it is a pain in the ass to get it to work with Lion and 10.6.8 update. However, that is unless you are lucky ( I explain how lucky you must be below…) After a bunch of searching I think I have finally narrowed it down to the specific cause to the problem. First lets begin by analyzing my symptoms.
Following Multibeast tutorial:
- I am successfully able to update to 10.6.7 no hitches, just remember to roll back USB.
- I cannot, for the love of all things holy in heaven, boot into 10.6.8 after the combo update and proper re-kext. Even in safe mode, single user and graphicsenabler=no flags. I have tried Verbose mode however I cannot remember the exact error, I’ll post later if i try again anytime soon.
- Note, this error I get is consistent, even when trying Kakewalk’s tutorial and when trying to boot INTO lion’s installer.
- So I can’t update to 10.6.8, big deal. You can upgrade to lion anywhere form 10.6.6 and above. So I proceeded to do so exactly. No go. It seems after creating a partition for the installer, running xMove, and (on other trials) remove IntelHD next and power management next (exact ones I cannot remember, I should post more often while I’m doing these things….), it is impossible to boot INTO the lion installation. Since I cannot even boot into the installer partition (even with latest Chimera boot loader) I just am stuck with a 10.6.7 build for now.
- The problem, as I hinted above most likely has to do with the video card (I think, still not definitive). I found this blogger: x2jiggy who had the same problem/ symptoms as I did. He however could boot into the lion installer ONLY in safe mode with limited graphics support even after installation. This is what he had to say:
The only way many users were able to overcome this was to flash their graphics card with a different BIOS that allows native support. This made me a little nervous as flashing a device can brick it which renders it useless but determined to complete the lion upgrade I had run out of options and this appeared to be the only solution. Following the messages of forum users in this thread and the ATIFlash documentation, I flashed my HD 5770 with an alternative version of the XFX bios ( available here ) using ATIFlash. The basic process involves making a bootable DOS USB Drive ( I used the HP Boot Utility) including the BIOS file and ATIFlash. My current BIOS file was backed up using GPU-Z. I then booted into DOS and performed the flash.
- This seems promising however extremely risky. I have a bad tendency of braking things, so the last thing I have the balls for is to flash my video card, that too one I really like and don’t have money to replace if anything goes awry. I went around to google a bit more and found our man x2jiggy (autocorrected as piggly lol) wasn’t the only one the have success in flashing his video card. Here are some testaments:
I had first tried flashing my XFX 5770 with a Mac ROM (following instructions on Neowin forums). This was successful but the card (using a vervet framebuffer) still did not work using the 10.6.8 ATI kexts (had to go back to 10.6.7 ones).I then flashed the PC Bios mentioned above, and now the 10.6.8 kexts do work. I am only using the two DVI ports, so I can’t comment on the 3 monitor situation.I borked my Lion install (another problem) so I can’t test the newly flashed card on Lion for a few days.
The procedure in short was:
Download a Win95 boot drive iso
Burn the iso onto a CD
Verify that you can boot to the CD and get the DOS prompt
Back on the Mac, create a FAT partition on a drive (I used an old SATA drive and made a 20GB FAT partition)
Download the atiflash utility, put it on the DOS drive
Download the ROM file above, rename it to a DOS friendly name and put it on the DOS drive
Boot using the CD, change to C: to access the DOS partition
save the existing card ROM (in case you need it later)
upload the new ROM to the card
Reboot back to the Mac
Clearly not for the faint of heart- there is a danger of bricking your graphics card.-agrajag (a geek in training at Tonymac’s site)
