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. -rak-
