Its much better to test it in the simple config of a motherboard with

Read the thread "meaning of 'rdisk()' in boot.ini file". I re-ran the
entire experiment with the 3 HDs connected to the motherboard IDE
controller, and exactly the results were found - rdisk(n) refers to the
hard drive having a displacement "n" from the head of the hard drive
boot order.

http://support.microsoft.com/default.aspx?scid=kb;en-us;q102873:

"Theoretically, this syntax could be used to start Windows NT on any drive
in the system. However, this would require that all drives are correctly
identified through the standard INT 13 interface; since support for this
varies from disk controller to disk controller and most system BIOS only
identify a single disk controller through INT 13, in practice it is only
safe to use this syntax to start Windows NT from the first two drives
connected to the primary disk controller, or the first four drives in the
case of a dual-channel EIDE controller."


Thinking about it (again :), it probably can't be the boot order. Aren't
there BIOS/controllers that don't boot from all disks connected to them,
yet these disks may still have rdisk numbers and allow starting Windows on
them?
