> Roda RK886EX have LCD 15.1 XGA (1024x768) - works perfect.
> Roda RF8 - 17'' WXGA 1440x900 - blank (but lightened) screen (other init and OS
> booting is perfect with external LCD)
> The log file says nothing - when coreboot or seabios calls vga.bin - all is ok,
> like on Roda RK886EX.
> Please, help me. Where and how i can fix that?
> I build coreboot, choosing Roda motherboard, adding compiled SeaBIOS image (I

> I include my log from COM1.
it looks like your option rom does not match the graphics device
PCI: 00:02.0 [8086/27ae]
Your option rom seems to be for 8086/27a2 ...
Please also increase the log level of SeaBIOS.
