SeaBIOS needs to write to the f-segment. So it needs to have some way to set that from read-only to read-write, write in it and when it's done set it to read-only again. On PCI we have a mechanism for that. The ISA machine does not though. To stay regression free and happily enable users to continue using the -M isapc machine let's just map it as RAM. The BIOS on PCI will set it to r/o later either way. Signed-off-by: Alexander Graf <address@hidden>
Thanks Alex. Figuring out what to do here has been on my todo and this seems like a reasonable solution.
