Grub Dual Boot Configuration

[ToonArmy]

I am having trouble dual booting my Ubuntu (which I have been loving since Hoary) with Windows XP. I have searched around this place and the mailing lists, and google, but haven't turned up exactly what I want.

I run Ubuntu from a SATA disc (sda) and Windows from an IDE disc (hda) both are installed in the first partition of the drive. Everyone else wants to know how to boot Windows from SATA and Ubuntu from IDE, I want the opposite and I am not having much success. I have tried various hacks at the instructions given nothing really works, my grub config for XP is included below.

Currently when I hit to boot XP from grub the screen flicks colour from a black to a more greyish black, I am guessing this maybe NTLDR taking over but thats all that happens.

I would like to avoid chaining grub from NTLDR and fiddling the BIOS everytime I want to go to Windows is getting rather annoying, then of course to get back (which I want to do ASAP ofc) is more annoying because I have to babysit until the Ubuntu disc is back in the driving seat.
