I wrote a boot sector for the NT boot loader to do exactly that two days ago.
What it does is relocate itself, load the boot sector from the second disk
(actually the next bios disk) and pass the control over. You might be able to
use booteasy instead, but I haven't tried.

Save the attached file, uudecode, copy to NT's root directory and add a line
to NT's boot.ini like,
	C:\BOOTSECT.NXT="Next Disk"
I can post the source if anyone is interested.
