Dual-Booting XP/FC2 with Grub on MBR, SATA not in device.map

Ok i've asked this question at linuxquestions.org and had no luck there so i'll try here.

i'm currently trying to get grub (day 2 trying to do this) to boot win xp which is located on my sata hd, but i don't know how to get linux to detect my sata drive. The reason why it didn't detect it in the first place because i unplugged my SATA hd before i installed FC2 on my IDE hd.

Using fdisk -l i have:

************************************************** *************************************************

in my /boot/grub/device.map i have:

************************************************** *************************************************
(fd0) /dev/fd0
(hd0) /dev/hda
(no sata drive in here)
************************************************** ************************************************

Now i've plugged my SATA back to my computer and i'm trying to get linux to detect it in
device.map so i can edit my grub.conf to boot windows XP. I've tried editing the device.map by adding the line >> (hd1) /dev/sda but that trick didn't work =(.

i'm thinking of following the intructions from a HOWTO in this thread:
http://www.linuxforums.org/forum/viewtopic.php?t=3181 but i'm not sure whether to do it or not since i might cause damage to the computer.

Any ideas or help on how to go about this would be greatly appreciated.
