Check-out kexec and possibly grub.exe.
What you can do is build a RAM disk with grub.exe as the
kernel and boot it with command line options that will boot
any of your other disks. Kind of "neat" ....
I use it as part of anaconda / kickstart to re-flash the BIOS
by booting up a DOS system (when flashrom does not [yet]
work) and then boot back into the kickstart.
Unfortunately, kexec really only works in fairly recent
kernels, however. So, that may be an issue for you.

Given that I have a machine with possibly multiple disks, each of
which is bootable(has an MBR)....
Is there a command that will query the BIOS and tell me which disk
is the default boot disk. BTW - this is x86.
The goal is to remotely reboot the workstation into the desired
disk(which contain different centos versions).
