[Qemu-devel] 128Kb bios size and older machines?

[Michael Tokarev]

Since the "small" (128Kb) seabios is now built without
support of xen, does that mean that xen will be unable
to use qemu with -M 1.7 and before?  Does it _ever_ use
-M option like this?

I'm asking because I don't really understand how this works.
 We updated seabios in debian to 1.7.4 (with qemu 1.7), it
grew past 128Kb, and now I'm trying to understand what
exactly is broken and how to fix it.  I should either
build it w/o xen support for it to fit in 128Kb again,
or keep it at larger size and live with (migration) breakage
caused by different bios size.

BTW, recompiling seabios-1.7.4 without xchi and a few other
recently added stuff (pvscsi boot et al) with gcc-4.7.2 on
debian does not produce 128Kb binary, it is larger than 128k,
so I can't produce 128kb bios on debian anymore.. ;)

Thanks,
