I could not find good instructions and had to try out things before it started working, but the process itself is fairly simple. Here are the steps:</p>https://jeltsch.org/en/how_to_boot_into_the_bios_of_a_dell_precision_workstation_410mt_to_change_to_scsi_booting/Tue, 06 Mar 2007 00:00:00 +0000https://jeltsch.org/en/how_to_boot_into_the_bios_of_a_dell_precision_workstation_410mt_to_change_to_scsi_booting/<p>Why do all hardware producers make up their own key combinations to access the BIOS?

Grub writes its guess of hard disk order to /boot/grub/device.map, but the guess was wrong in my case.</p>
