Unusual boot.ini add boot device request.

[reboot]

Got a customer who insists on dual booting two copies of XP Pro.
He's spent a small fortune on Licenses, and hardware, but I'm trying to do this the easy way.
Scenario:
Two hard drives, both primary, active, both bootable, running XP Pro. Boot selection is currently made by going into BIOS setup and selecting boot device.
Both have identical boot.ini files.
Hard drive 1 is on an aTA100 controller card, bootable in BIOS by selecting SCSI, and disabling HDD-0.
Hard drive 2 is on the motherboard IDE, primary master, bootable by switching the boot device to HDD-0 in BIOS.
Boot.ini files identical as follows:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect

If I were to set BIOS to boot from the hard drive 1 on the controller, what would I add to the boot.ini to get a dual boot menu?
I'm thinking it's something like this:
multi(1)disk(1)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
but really haven't a clue.
He want's the boot loader menu to ONLY appear if booting from hard disk 1 on the controller, so he can still manually change it in BIOS as well, but does NOT want a boot menu to appear, when booting to hard disk 2 on the motherboard IDE controller.

The easy way is to add something to boot.ini
The hard way is to set boot to the CD-ROM first, controller second, disable HDD-0 and run a repair to get the correct boot.ini

Please give me the easy way

Hi 'boot,

I wouldn't know exactly how, but hopefully this link will help you out:

Nice link, but no help at all.
I suppose I could go through all the possible permutations, but...another thought...
In disk management, it's labeled drive "H".
So, would that boot.ini entry be:
multi(0)disk(1)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
or would it be:
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
Any ideas?

p.s. Welcome back Flopster!

Thanks reboot!

Heck if this were my situation I'd play with it until it works, but I can understand that you don't want to do that. With that I hope someone else who experience with this will jump in.
