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

248 * strange things when they come into contact with PCI bridge chips. The
249 * net result of all this is that the PCI card that is actually used to boot
250 * the machine is very hard to detect. Most motherboards go from lowest
251 * PCI slot number to highest, and the first SCSI controller found is the
252 * one you boot from. The only exceptions to this are when a controller
253 * has its BIOS disabled. So, we by default sort all of our SCSI controllers
254 * from lowest PCI slot number to highest PCI slot number. We also force
255 * all controllers with their BIOS disabled to the end of the list. This
256 * works on *almost* all computers. Where it doesn't work, we have this
257 * option. Setting this option to non-0 will reverse the order of the sort
258 * to highest first, then lowest, but will still leave cards with their BIOS
259 * disabled at the very end. That should fix everyone up unless there are
260 * really strange cirumstances.
