Hi,
The option rom stuff has a number of short comings. Because we hijack int19, extboot doesn't get to run. That means that if you use -kernel to load a grub (the Ubuntu guys for their own absurd reasons) then grub does not see extboot backed disks. The solution for them is the same, generate a proper disk and boot from that disk.
Oh, having extboot + linuxboot + multiboot register a BEV (correct acronym?) entry instead of hijacking int19 would fix that too. Additional bonus will be that they are selectable in the boot menu.
cheers, Gerd
