[solved] Black screen when booting installation

Question

The basic problem. I have a HD6870, my monitor is connected through DVI (& my second one through HDMI). No integrated graphics.
After I try to boot the x64_86 version, the screen goes black after 'booting kernel'.
Things I've tried:
radeon.modeset=0 (gives drm:radeon_init [radeon]] *ERROR* no UMS suppot in radeon module)
radeon.modeset=1 (black screen)
nomodeset (drm:radeon_init [radeon]] *ERROR* no UMS suppot in radeon module)
disconnected second screen (black screen)
video=SVIDEO-1:d (black screen)
i915.modeset=0 (I have no intel, but black screen)
acpi=off (doesn't work either).
It is driving me crazy. Can someone help me?
EDIT:
Solved by upgrading BIOS

Answer 1

Should this be on or off?
Edit: Only thing remotely close I could find was legacy USB settings, but those just disable my keyboard in the arch install.

1 videocard
Lone_Wolf wrote:Another possibility :
Maybe linux does send output to a wrong monitor. Could you try booting with only 1 monitor connected ?
I initially thought the same, tried with DVI, HDMI single and double monitor, but it didn't work.

See above.
EDIT 2: putting HD in AHCI mode makes just the screen black. Backlight stays on. In Knoppix and Ubuntu it makes the kernel hang at booting kernel _
