Hello This is my first post and I found this forum incredibly helpful. I am currently working on an external hard drive that has Snow Leopard installed on it that works on most of the computers in my home. I currently have all of the Intel computers booting off the Hard Drive (Easy enough) But I'm having trouble getting it to boot off the AMD laptop. I am booting off Chameleon and using -v to see what the problem is and this is the error ATI Card posted, reading VBIOS from legacy space Frame buffer set to device's default: Nr of ports set to frame buffer's default: 0 It doesn't go any further. Just stops there. Help would be appreciated thanks! One of the main problems I'm running into is my computers motherboard is custom built by Samsung (305v4a/305v4a) so I'm not sure what Kexts to use because of compatibility. P.S My hardware specs are in my signature.
