Dependency between Xorg and VideoBIOS

[Eduard Fuchs]

Hello,

Currently, I have a PowerPC embedded system with PCI Radeon 9200 PRO 
graphic card (RV280) on it. At first, the Linux Kernel runs the 
VideoBIOS during x86emu and init the PCI-card. After this, the kernel 
radeonfb and the radeon driver from Xorg work very well.

Now we are making board redesign with new on-board graphic chip. Our 
choice is ATI E2400, unfortunately without VideoBIOS. The question is - 
how deep depends the Xorg on Video-BIOS?

We want try to init the E2400 during system boot (in u-boot or later in 
linux kernel) thru pushing some init values in the chip's registers.

Where can I find some more information about this problem?


Thank you very much in advance!

Best regards
