The host adapters are listed in the ISA and PCI 5256a8d6623SGarrett Wollman# device configuration sections below. 5266a8d6623SGarrett Wollman# 527265368d4SRodney W.

In earlier versions the unit numbers were assigned 530ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus. This 531ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite 532ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding 533ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device 534ebc1a0e2SPeter Dufault# configuration around. 535ebc1a0e2SPeter Dufault 536ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.
