My guess is that mucking with interrupts is not going to help. There is usually an option to affect the boot order, typically named something like "Boot Off-Board controllers first". If you can give the model number of the server, we can probably lookup the BIOS manual online and maybe give better advice. It should also be possible to write a boot sector to the IDE disk that will boot from the SCSI disk. If your /boot partition is /dev/sda1, something like this might work: #echo "(hd0) /dev/hda" >/boot/grub/device.map.ide #echo "(hd1) /dev/sda" >>/boot/grub/device.map.ide # grub --device-map=/boot/grub/device.map.ide grub> setup (hd0) (hd1,1) ... grub> quit But, fair warning, I've never tried this, so I'm not sure how well it will work. -Richard -- gentoo-user@gentoo.org mailing list
