But grub knows which is hd0 by the entry in the /boot/grub/device.map file. We found that sometimes with SATA disks you have to fool around with the SATA options in the BIOS to make them work properly in a fedora - windows double boot. I admit I have never tried this with a SATA - IDE combination but I suspect you are ok as long as you don't depend on the IDE drive to be the one that is looked at to find the MBR by default. -- ======================================================================= Torque is cheap. ------------------------------------------- Aaron Konstam Computer Science Trinity University telephone: (210)-999-7484
