GRUB and W2K/XP on IBM T41p Thinkpad

[Hose]

I have FC2 running on an IBM Thinkpad T41p as well as additional HD with Windows 2000. Rather than shutting down and swapping HD's, I'm trying to use GRUB to boot the second HD (w2K) when inserted into the Ultrabay with an IBM IDE HD adapter.
After researching the web, the windows portion of my GRUB config file that looks like:

title W2K
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd0,0)
chainloader +1
makeactive

When I select W2K from the GRUB menu, I get:

"Error 13: Invalid or unsupported executable format"

fdisk shows that /dev/hda is FC2, /dev/hdc is W2K.

I've tried removing the mapping, but no change, anybody out there has any suggestions ???
Any thoughts

take out the last line "make active" and it may work.....and make sure is also setup in your bios.

Hey imdeemvp, thanks for the quick response, tried your suggestion and still NG. my BIOS is setup to boot from Hd0, Hd1, ....

[imdeemvp]

/dev/hdc is W2K in the grub lines replace the numbers with 2 or 3 because /dev/hdc IS NOT one for sure....may be for #3 or 2

Nah, tried that too without success. Is there any changes to the W2K bootloader needed ???
