[coreboot] Help required to boot DUET (Seabios floppy mechanism)

[Anthony Ross]

Hello Coreboot Folks,

Well Thanks for the suggestions. It seems that  DUET boots but now a major
problem has cropped up. It freezes at the main DUET-BIOS page not allowing
to perform any further operations, like booting a HDD image or fingering
around the EFI BIOS options. Similarly If I had the .lzma to the cbfs file
name I face the same problem like earlier so having it as myfloppy.img
makes it take effect.


Any further Ideas about these problems.....


Regards..


Neo
