Thanks for reporting this.
After compiling seabios with CONFIG_DEBUG_SERIAL set in src/config.h
and running:
qemu -M isapc -serial file:foo
I see:
Unable to unlock ram - bridge not found
SeaBIOS stores global variables in the f-segment. This greatly
simplifies the code, but it does require the ability to write to the
f-segment. Since the f-segment can't be unlocked in "isapc" mode, the
boot fails.
I'm not really sure what to do about this. Maybe some kind of non-pci
method of unlocking the f-segment could be implemented.
Anthony, what do you think?
