[CentOS] Dual-boot with WinXP, CentOS already installed

Hi all,

I'd like to deploy a solution with dual-booting systems where CentOS 5.3 is 
already installed and WinXP will be installed to a separate disk.

I found 
http://apcmag.com/how_to_dual_boot_linux_and_windows_xp_linux_installed_first.htm?page=1 
and it seems straight forward enough, although the description is for Ubuntu.

The problem as I see it, is that the how-to differs from how CentOS looks in 
/etc/grub.conf and the boot-loader in Ubuntu with respect to making grub work 
again after the Windows install.

I found Tldp.org mentioning dual-boot plenty, but most or all articles listed 
are using lilo as a boot-loader, which seems a bit obsolete and besides I 
can't quite translate the instructions from lilo to grub. 8-/

Basically, what would I need to change in the how-to from apcmag.com above?? 
Thanks for any pointers.
