Keep loading custom roms (e.g. from -option-rom)
starting at 0xc8000. Modify SeaBIOS to scan the memory range for
pre-deployed option roms before deploying PCI roms. SeaBIOS will
find the last pre-deployed rom and have a starting address for
deploying PCI roms. This will keep ISA option roms working.
Unfortunately, if the SeaBIOS post entry gets called again (eg, on
ctrl+alt+del), it wont know which roms were originally present, and
which roms were deployed by SeaBIOS on the first boot.
option roms loaded by seabios via pci seem to care only about the pci
device they where loaded from. So this optionrom <=> pcidevice
relationship must be stored somewhere. Can SeaBIOS use that to figure
which option roms where loaded by seabios itself?
