My guess is that mucking with interrupts is not going to help. There |
| 22 |
is usually an option to affect the boot order, typically named |
| 23 |
something like "Boot Off-Board controllers first". If you can give |
| 24 |
the model number of the server, we can probably lookup the BIOS manual |
| 25 |
online and maybe give better advice. |

It should also be possible to write a boot sector to the IDE disk that |
| 28 |
will boot from the SCSI disk. If your /boot partition is /dev/sda1, |
| 29 |
something like this might work: |
| 30 |
|
| 31 |
#echo "(hd0) /dev/hda" >/boot/grub/device.map.ide |
| 32 |
#echo "(hd1) /dev/sda" >>/boot/grub/device.map.ide |
| 33 |
# grub --device-map=/boot/grub/device.map.ide |
| 34 |
grub> setup (hd0) (hd1,1) |
| 35 |
... |
| 36 |
grub> quit |
| 37 |
|
| 38 |
But, fair warning, I've never tried this, so I'm not sure how well it will work. |
