For instance, the PC BIOS boot specification allows only one
disk to be bootable. If boot from disk fails for some reason, the BIOS
won't retry booting from other disk. It still can try to boot from
floppy or net, though.I want to know that if seabios support retry booting from other
SeaBIOS follows the specifications, and so only the C drive can be
booted. Unfortunately, once the C drive is assigned it can't be
changed reliably. So, ultimately SeaBIOS has the same limitation as
other BIOS here.
What is the problem here? Fall back to ide/sata hard disk when booting
from usb stick (which is treated as hard disk too) failed would be useful.
It certainly would be a non-trivial change to the boot order code as
this would involve changing the disk mapping, rewriting edd tables and
But on a quick glance I can't see why it wouldn't work reliably.
