Shane 2 Posted January 12, 2013 Share Posted January 12, 2013 I got 10.8.3 booting without problem on my HD 5770. I installed my system with iATKOS ML2. So, it's hopefully clean enough, but when I put HD 7770 on, it gives me an error. Chameleon r2140, with boot flag: GraphicsEnabler = YES Here's what's on my screen: boot0: test boot0: error boot0: error boot0: donexv blah blah blah...... Not really explanatory to me. UPDATE: So, I tried booting with HD 5770 in the first slot, screen connected, then HD 7770 in the second slot. It boots without problem, and after it boots, I can plug my display to 7770 with no problem. Once I switched the slots, problem start. The problem with this setup is that slot 2 is a x16 slot. I can plugged 7770 on second slot with 5770 in first slot, but nothing shows up until login window. Link to comment Share on other sites More sharing options...
Onixs Posted January 12, 2013 Share Posted January 12, 2013 Its not your OS nor your setup. Its your HD being a 4k. Google on chameleon+4k to fix it Link to comment Share on other sites More sharing options...
iFIRE Posted January 12, 2013 Share Posted January 12, 2013 Edit your topic, your card is 7770 or 5770? ok, this is the second option for install it, download binarios chameleon folder i386 1. open the folder i386 and copy boot1h for your USBInstaller. 2. boot from USBinstaller and go for utilities and open app Terminal 3. type diskutil list for identified your disk and partition were you installed of system ML = "(i.e: disk0s2)" 4. type diskutil unmount disk0s2 5. type cd / 6. type dd if=boot1h of=/dev/disk0s2 bs=4096 7. reboot in steep 6 put your disk and partition "(i.e disk0s2 "), see your 1 Link to comment Share on other sites More sharing options...

eep357 Posted January 12, 2013 Share Posted January 12, 2013 It's due to larger vbios on 7xxx cards. It cause a bunch of alien looking text after Boot0:Done. Newest Chameleon helps for some, but for me the only way to get past this was to install Chameleon/Clover onto a mbr formatted drive instead of guid. I used a USB when first testing to get it working. Once you get past that, your next problem will be booting to a blank screen, the trick to get past this is to sleep and wake the computer. If you have automatic login enabled, disable it so you don't have to wait for all the desktop stuff to load before you can sleep and make screen work. Also make sure sleep works with your 5770 first so you know your system can sleep/wake. I had a 5770 I had to switch back to a few times while figuring all this stuff out 2 Link to comment Share on other sites More sharing options...

eep357 Posted January 13, 2013 Share Posted January 13, 2013 Difference is one works and the other doesn't. Really, there's no good reason, just the way it is at the moment. Link to comment Share on other sites More sharing options...
Sipheren Posted March 9, 2013 Share Posted March 9, 2013 Difference is one works and the other doesn't. Really, there's no good reason, just the way it is at the moment. Has anything further been done regarding this? I have installed the latest Chameleon but it still gives me a line of weird text. I have installed Chameleon onto a USB formatted with a MBR and I just boot from that. I have a HD7770, just upgraded from a HD5770, didn't realize their would be so many issues with it Link to comment Share on other sites More sharing options...
rayap Posted August 15, 2013 Share Posted August 15, 2013 Works on my guid formatted SSD with Chameleon. Edit: Works on normal GUID disks too. Used boot0af. Link to comment Share on other sites More sharing options...
