Is it possible to modify/inject some code into the bios of, say, an asus p2-99 (440zx-based, award bios) to make it send out either to vga or a serial port the registers that it programs on the northbridge, as it's doing it? Or can this info be obtained through reverse engineering? And as far as bricking the motherboard goes, if anyone may be concerned with that, I have a BIOS savior.
Or, could I somehow do this through QEMU or VMWare, since both of these emulate 440bx chipsets, use the p2-99's BIOS along with some userspace tool?
edit: Probably should have mentioned, I'm only interested in up until and including sdram initialization
