The host adapters are listed in the ISA and PCI # device configuration sections below. # # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so # that a given bus, target, and LUN always come on line as the same # device unit. In earlier versions the unit numbers were assigned # in the order that the devices were probed on the SCSI bus. This # means that if you removed a disk drive, you may have had to rewrite # your /etc/fstab file, and also that you had to be careful when adding # a new disk as it may have been probed earlier and moved your device # configuration around. # This old behavior is maintained as the default behavior. The unit # assignment begins with the first non-wired down unit for a device # type. For example, if you wire a disk as "da3" then the first # non-wired disk will be assigned da4. # The syntax for wiring down devices is: hint.scbus.0.at="ahc0" hint.scbus.1.at="ahc1" hint.scbus.1.bus="0" hint.scbus.3.at="ahc2" hint.scbus.3.bus="0" hint.scbus.2.at="ahc2" hint.scbus.2.bus="1" hint.da.0.at="scbus0" hint.da.0.target="0" hint.da.0.unit="0" hint.da.1.at="scbus3" hint.da.1.target="1" hint.da.2.at="scbus2" hint.da.2.target="3" hint.sa.1.at="scbus1" hint.sa.1.target="6" # "units" (SCSI logical unit number) that are not specified are # treated as if specified as LUN 0. # All SCSI devices allocate as many units as are required. # The ch driver drives SCSI Media Changer ("jukebox") devices. # # The da driver drives SCSI Direct Access ("disk") and Optical Media # ("WORM") devices. # # The sa driver drives SCSI Sequential Access ("tape") devices. # # The cd driver drives SCSI Read Only Direct Access ("cd") devices. # # The ses driver drives SCSI Envinronment Services ("ses") and # SAF-TE ("SCSI Accessable Fault-Tolerant Enclosure") devices. # # The pt driver drives SCSI Processor devices. # # # Target Mode support is provided here but also requires that a SIM # (SCSI Host Adapter Driver) provide support as well. # # The targ driver provides target mode support as a Processor type device. # It exists to give the minimal context necessary to respond to Inquiry # commands.

Note that the D-Link DFE-530TX+ uses the RealTek # chipset and is supported by this driver, not the 'vr' driver. # sf: Support for Adaptec Duralink PCI fast ethernet adapters based on the # Adaptec AIC-6915 "starfire" controller. # This includes dual and quad port cards, as well as one 100baseFX card. # Most of these are 64-bit PCI devices, except for one single port # card which is 32-bit. # sis: Support for NICs based on the Silicon Integrated Systems SiS 900 and # SiS 7016 PCI fast ethernet controller chips. # sk: Support for the SysKonnect SK-984x series PCI gigabit ethernet NICs. # This includes the SK-9841 and SK-9842 single port cards (single mode # and multimode fiber) and the SK-9843 and SK-9844 dual port cards # (also single mode and multimode). # The driver will autodetect the number of ports on the card and # attach each one as a separate network interface. # sn: Support for ISA and PC Card Ethernet devices using the # SMC91C90/92/94/95 chips. # sr: RISCom/N2 hdlc sync 1/2 port V.35/X.21 serial driver (requires sppp) # ste: Sundance Technologies ST201 PCI fast ethernet controller, includes # the D-Link DFE-550TX. # ti: Support for PCI gigabit ethernet NICs based on the Alteon Networks # Tigon 1 and Tigon 2 chipsets.

Note that you will # probably want to bump up NMBCLUSTERS a lot to use this driver. # tl: Support for the Texas Instruments TNETE100 series 'ThunderLAN' # cards and integrated ethernet controllers. This includes several # Compaq Netelligent 10/100 cards and the built-in ethernet controllers # in several Compaq Prosignia, Proliant and Deskpro systems.
