installed Mandrake Linux 10.1 alongside Windows XP (on another hard drive).
So now I have a dual-boot system and everything seems to run perfectly...
except my mouse doesn't work. It just stays fixed in the middle of the screen.

It is really important that I get the mouse to work. I've tried usb mice and

ps2 mice, but none work. Installing another linux distro is not an option, and

I'd only do a kernel recompile as a last resort.

This shouldn't really be too hard for you linux gurus.
I'd really appreciate it if anyone could help me -- you'd save my life, and

have my eternal thanks!

system:
IDE ATA drives:
hda: 80GB - Windows XP Professional SP2
hdb: none
hdc: 80GB - Mandrake Linux 10.1
hdd: Sony CD/DVD-Rom

I use NTLDR (windows' bootloader) as my default bootloader, which in turn

chainloads LILO for Mandrake.

I don't get any error messages at boot.

My usb is a standard onboard usb 2.0 socket, and my motherboard is a Gigabyte

2004 GT model, if this helps.
