Thread starter Xalalau; Start date Nov 13, 2014; Xalalau. Nov 13, 2014 #1. I would like to ask you for help to get the BIOS of Radeon HD 6470M 1 GB. It's been two years that my card stopped working and now I'm trying to resurrect it again. Now I understand: the bios is only one and it's good in my case.
Re: Radeon 6470m Project Ok well screwing around today I deleted the smbios and dsdt and I couldn't boot anymore. So I had to go into my backup partition to try and replace it and I couldn't even get into it using rBoot so I thought I was screwed.
Anyway I thought i'd throw in 1 of my old redundant non retail disks which used Chameleon v2.0-RC5 r1135. This is the only version that even remotely detected my ati card: FRAMEBUFFER @0xB0000000 MMIO @0xD4900000 I/O Port @0x0000 5000 Rom address@0xFFFE0000 ATI card POSTed, reading VBIOS from legacy space Unfortunately when it got to this point it restarted. NOTE dabeidl posted a similar outcome from some tweaks however my I/O port says 5000 and His says 3000 Maybe we should make a list of which boot loaders have been tried and which have had results.
