GRUB and Windows XP

[Chamindu Ruwin Munasinghe]

Hi ,
        I dont know weather this is the correct place to ask this question. If not please indicate where i can post this.

        My problem is like this , my machine had red hat linux 8.0 installed on the first partition of my disk. then i installed windows xp onto a new partition. now the partitions are like this

        1 - linux
        2 - linux swap
        3 - NTFS (XP)
the windows xp setup has marked the 3rd partition as the active one. after the xp installation. i used the linux rescue mod to make partition 1 active again and install grub ( grub-install /dev/hda1) now how can i make a boot menu entry to boot onto Windows XP

Thanks
Chamindu
