VGABIOS for ATI Mobility Radeon 5470 needed (Virtualization)

[bug!]

Execute the following (replacing __PCI__ with your cards PCI, for example, 0000:02:00.0):

sudo su
echo "1" > /sys/class/drm/card0/device/driver/__PCI__/rom
cat /sys/class/drm/card0/device/driver/__PCI__/rom > ~/vgabios.bin
echo "0" > /sys/class/drm/card0/device/driver/__PCI__/rom

The VGABIOS will then be in your home folder.
(You should however check the vgabios with your favorite hex editor to make sure it's the vgabios in there, and not an error message, for example. Or "cat ~/vgabios.bin", you'll notice if it's the vgabios or not)

However, there are also other methods, for instance ATITool (Win64/Win32/Dos) etc..

thank you.
but that doesn't work, because my host does not recognize the card So there are no entries in /sys/ for the radeon card...

with gpu-z or the atitool it is also not possible to get the bios. Maybe sony did blocked the bios?

Forgive my ignorance, but can't you simply run those commands in the *guest* (with the FOSS radeon drivers loaded) to extract the VBIOS?

the problem is, that the *host* don't recognize the video card. Error message:
radeon 0000:16:00.0: Invalid ROM contents.
drm:radeon_get_bios] *ERROR* Unable to locate a BIOS ROM"

So I tought, if I can read somehow the bios, I could implement it as workaround in radeon_get_bios() function.
