Problem with boot loader

[badmagic]

Hi all,

I have 2 SATA drives - Windows on the sda and have just installed FC12 
on sdb. I installed
the boot loader on sdb.

Now, I'm using the XOSL boot manager (installed on its own dedicated 
primary partition
on sda).

If I change the boot sequence in the BIOS to boot from the disk that has 
the Fedora install
on it, it boots fine but if I try to boot from XOSL, I just get a black 
screen with the cursor
flashing in the top left corner. Does anyone know what's going on and 
how to fix it?

Regards,
Steve Laurie
