[coreboot] FILO loads image but, Linux doesnt boot

[Phani Babu Giddi]

Hi Uwe,

Thanks for the tip.

Actually Linux was starting and everthing was working fine. Its just that I
cannot see anything on the display. The messages that I get on the serial
console are just similar to what I would get when booting from the commerial
BIOS and GRUB.

What do you think is missing, I was under the impression that VGA ROM is
only required only for the BIOS and the kernel has its own driver.

Let me remove the vga=0x317 and make it normal and see how it goes.

Any other inputs are welcome.

Regards,
Phani
