Of course. You have to format a floppy disk, copy the software (blizzppcupdate or whatever is called) to the floppy disk, make the floppy bootable using the install command (install df0:), then reboot... enter to early startup, disable your hard drives (all partitions), insert the floppy disk in your DF0:, boot with no startup sequence and execute the program once on the CLI with the options you've been told before (force and such). That's it.
Hope that helps,
