Hello Ignacio.

Upgrading your BIOS when needed is an harmless procedure that if 
observed with a little attention (dl the correct image and follow ALL 
instructions) is very simple.

That said your boot setup has nothing to do with BIOS. You would greatly 
simplify your life if you installed GRUB (or LILO) to your /dev/hda 
master boot and let it handle the situation.

In case of GRUB these lines will flawlessly boot your XP if you have one 
(in my case on /dev/hda1) and Linux (in my case two different kernels on 
/dev/hda7). Note that (hd0,0) in GRUB parlance means first disk, first 
partition or /dev/hda1) since it's notation is zero based.

HTH,
Bob
