- * Certain PCI motherboards will scan PCI devices from highest to lowest,
- * others scan from lowest to highest, and they tend to do all kinds of
- * strange things when they come into contact with PCI bridge chips.  The
- * net result of all this is that the PCI card that is actually used to boot
- * 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
- * really strange cirumstances.
