We should fix qemu to re-read bios from flash.
Makes sense?
We have option_rom_setup_reset() already.
We don't, anymore :)
We are fast! Well, we surely have something similar instead.
Sure. Try 'info roms'. Everything listed there will be reloaded on
reset (unless mem=rom, in which case the guest should not be able to
modify the bits in the first place). That includes vgabios,
optionroms, -kernel images, ...
And what about bios? I don't see it there.
pc.c does some magic here to map the complete bios into high memory and
the legacy part at 0xe0000, thats why it is loaded in a different way.
It gets loaded to IO_MEM_ROM memory though, so the guest should not be
able to corrupt it.
cheers,
Gerd
