[LinuxBIOS] VGA Support on AMD DB800

[Omar Esteves Duarte Filho]

Hello!

I'm trying to use LinuxBIOS with AMD Geode DB800 platform. However, until
now, I could not manage to get VGA output working.

Here is a summary of what i've tried:

- built a LinuxBIOS rom image without VGA support.
- downloaded a brand new kernel from www.kernel.org (kernel version:
2.6.23.9).
- configured this kernel, enabling these options:
 [*]   AMD Geode family framebuffer support (EXPERIMENTAL) 
 <*>     AMD Geode LX framebuffer support (EXPERIMENTAL)

- editted GRUB's menu.lst file to include the following entry:

title		Ubuntu, kernel 2.6.23.9-geodelx-fb
    root		(hd0,1)
    kernel		/boot/vmlinuz-2.6.23.9-geodelx-fb
root=UUID=b40ebb15-49bd-4042-ab40-5437c0caa1ba ro quiet splash pnpbios=off
    initrd		/boot/initrd.img-2.6.23.9-geodelx-fb
    quiet
    savedefault

- compiled fbcon as a module.

However, if I try to modprobe fbcon, i get nothing. Running startx also
gives me no result... Does anyone have any idea or clue about this?

Thanks!

Regards,

Omar.

Hi Omar,

There is no Geode graphics support in LinuxBIOS. You need to install the
  Geode framebuffer driver for console graphics and the X driver for X
support on your Geode Linux image. Until the driver loads there is only have
serial console output.
