On certain UEFI systems, we may need to use an alternative method to
fetch the vbios, so we probably need to export it from the driver via
debugfs.

Asus U38N: Unable to get Video BIOS on Radeon HD 7600G

[Paul Menzel]

Dear Linux developers,


as reported in the channel #radeon on , I am not able
to dump the Video BIOS on my Asus U38N-C4010H with AMD Radeon HD 7600G
(Trinity A8-4555M).

I am using Debian Sid/unstable with Linux version 3.12-1-amd64
(3.12.6-2).

$ cd /sys/devices/pci\:00/\:00\:01.0/
$ echo 1 | sudo tee rom
1
$ sudo cat rom > /tmp/vbios.rom
cat: rom: Input/output error

Am I doing something wrong or is this an error in the code?


Thanks,

Paul
