Title:
sgabios outputs incorrect video modes
Status in QEMU:
New
Status in sgabios package in Ubuntu:
New
Bug description:
When run with a bootstrap loader that uses int 0x10 with 0x1301 in
%ax, incorrect video modes are output to the serial port. I believe
the VGA image will be correct. This might also affect the returned
values for some interrupts.
This is caused because the set_cursor_position routine fails to save
and restore %bx.
I'm working on a fix for this.
