It works only with Cyrix FPU, and this option 124# should not be used with Intel FPU. 125# 126# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning 127# CPU if CPU supports it. The default is double-clock mode on 128# BlueLightning CPU box. 129# 130# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1). 131# 132# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct 133# mapped mode.

The host adapters are listed in the ISA and PCI 539# device configuration sections below. 540# 541# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 542# that a given bus, target, and LUN always come on line as the same 543# device unit. In earlier versions the unit numbers were assigned 544# in the order that the devices were probed on the SCSI bus. This 545# means that if you removed a disk drive, you may have had to rewrite 546# your /etc/fstab file, and also that you had to be careful when adding 547# a new disk as it may have been probed earlier and moved your device 548# configuration around. 549 550# This old behavior is maintained as the default behavior. The unit 551# assignment begins with the first non-wired down unit for a device 552# type.
