Well it's not that simple, to access the BIOS you switch into 16bit mode, and then issue an INT instruction. You don't want a real time OS, halting in the middle of everything, switching the processor so it can't see most of memory, including you
critical exception handlers and interrupts, and descend into the BIOS.
But if you search romInit.c code you'll see some mention E820 calls where VxWorks calls into the BIOS to get the memory map. (At least in recent IA BSPs)
You can copy that code to make other BIOS calls and save off whatever you like for later reference.
