Not to go any deeper into the issue, probably when installing chameleon the boot sector on the second hdd got corrupted somehow for some reason.

HDD with OSX is booting fine so no reason to modify it. I would unplug that hdd leaving only the one with XP and boot with XP CD, to console mode, enter you admin pass and log to windows installation when promted.

Here you can do:

and

After doing this it should be booting fine. You can plug in your osx hdd again. Other good solution is to add chain0 to windows xp boot.ini. This way you will have your xp hdd as first booting drive with an option to boot into osx. You won't need to change drives boot order every time.

Hope it helps.
