The bios can see it all right w/out necessarily being able to boot from it.
If you look at the IDE devices in your bios, I'm betting that they show up.
That doesn't mean they're all bootable. Older BIOSs may not boot from
anything other than the primary master.

I don't know how PCLinux's installation process works, so I can't say for
sure. You should attempt to install Grub (I wouldn't use Lilo, as there's
nothing it can do that Grub can't) on the MBR of your XP/Xandros drive. You
can then edit your /boot/grub/menu.lst file of your Xandros system to point
to the 2nd drive for PCLinux, allowing you to boot whatever you'd like.
There's no reason that I know of that it can't be made to do what you want.
You'll probably need to edit your menu.lst file to get it working though.

I hope you haven't clobbered your Xandros partition yet. There is a way to
simply install grub after you've installed PCLinux to get it all working.
There's a recipe for it in the Linux Cookbook by Carla Schroeder (O'Reilly),
which is a highly recommended book. If you still have your partitions
intact, let me know and I'll tell you the commands you need (from the book).
