should work as long as the boot ini on the primary drive looks like this
code:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(1)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(1)partition(0)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn
partition needs to be changed if your install of xp is on your d: not your c:
but that probally won't happen
that last bit isn't actually taking a new line
