 Please enable DEBUG_BIOS so that the information that is sent

[Replying to an old bugreport]

Current qemu has another debugging feature, which is enabled
by a special chardev, like this:

 -chardev stdio,id=seabios \
 -device isa-debugcon,iobase=0x402,chardev=seabios

This is for seabios itself, but probably not for vgabios.
Is that chardev not enough for your needs?

Upstream is now in process of removing the code around
this (parts in hw/pc.c which are enabled after #defining
DEBUG_BIOS), and the next version of qemy most likely
will use vgabios from the seabios sources, not from
the bochs project -- and that one will most likely
have different (and simpler) debugging provisions.

Thanks,

/mjt
