* Certain PCI motherboards will scan PCI devices from highest to lowest,

* the machine is very hard to detect. Most motherboards go from lowest
* PCI slot number to highest, and the first SCSI controller found is the
* one you boot from. The only exceptions to this are when a controller
* has its BIOS disabled. So, we by default sort all of our SCSI controllers
* from lowest PCI slot number to highest PCI slot number. We also force
* all controllers with their BIOS disabled to the end of the list. This
* works on *almost* all computers. Where it doesn't work, we have this
* option. Setting this option to non-0 will reverse the order of the sort
* to highest first, then lowest, but will still leave cards with their BIOS
* disabled at the very end. That should fix everyone up unless there are
