Hi,
Oddly, I can't boot from a hard drive (-hda) when I use the coreboot/seabios I built though. It keeps failing at "Booting from Hard Disk...".
I see that with my builds too, but only with -vga std (where coreboot vgabios is used). Same bios image with -vga cirrus works fine. So it seems this is triggered by the coreboot vgabios too.
(2) color attributes don't work correctly. Result is that you can't figure which line in your boot menu is highlighted. Visible in Fedora live isos (which use isolinux as boot loader) I think.
This isn't surprising as the vgabios handling of attributes in text mode is different from the handling in graphics mode. It may be possible to tweak seavgabios so it tries to emulate the text mode attr handling.
Ok, so simply not implemented.
cheers, Gerd
