The host adapters are listed in the ISA and PCI 6736a8d6623SGarrett Wollman# device configuration sections below. 6746a8d6623SGarrett Wollman# 675265368d4SRodney W.

In earlier versions the unit numbers were assigned 678ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus. This 679ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite 680ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding 681ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device 682ebc1a0e2SPeter Dufault# configuration around. 683ebc1a0e2SPeter Dufault 684ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.
