bochs bios required all 128kB, so this is probably a leftover.
This is apparently well defined in the PIIX spec. There is a bit
of a difference between the lower half and upper half of the BIOS
region though and I expect this is part of what the problem is.
FYI, the following patch works. Surprisingly, we only need to
restore the 0xe8000..0xe8fff region. Still trying to understand
what's happening.
SeaBIOS is currently using over 64K of space. So, it is extending
into the e-segment
and thus needs to have the e-segment copied properly (I missed that in my
earlier email).
Okay. So I assume this is something that SeaBIOS needs to do? I've
been trying to understand the origin of:
// Need to copy optionroms to work around qemu implementation
What is it that we're doing wrong in the qemu implementation? If it's
the lack of PCI option loading, then I guess we're okay post my changes
provided that SeaBIOS can take care of what it needs in the e-segment.
