I meant what is the best way to debug the qemu and seabios interaction, I don't necessarily want to inspect instructions but rather just the function calls and trace the process so I can compare it for another case that isn't working.

At first, I guess "-s" a.k.a qemu gdb stub of Qemu could help
you...but uhm, on a second thought, I think it is the qemu itself that
you need to run under Qemu...
regarding seabios code, i have no idea how to debug that... is it a
binary blob only?

Can somebody give me some pointers on what the best way to debug the boot process in Qemu and seabios?
Seabios reports that no boot device is present even though I'm passing it the hda commandline argument.
What I'm looking for in particular is what Qemu does to map the path to a device and how it passes this on to seabios.
Any information on debug switches, general description of the process would be extremely helpful.
