The host adapters are listed in the ISA and PCI # device configuration sections below. # # Beginning with FreeBSD 2.1 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 "sd3" then the first # non-wired disk will be assigned sd4. # The syntax for wiring down devices is: # disk sd0 at scbus0 target 0 unit 0 # disk sd1 at scbus0 target 1 # disk sd2 at scbus0 target 3 # tape st1 at scbus0 target 6 # device cd0 at scbus? # "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 "unknown" device (uk? in pre-2.1) is now part of the base SCSI # configuration and doesn't have to be explicitly configured. controller scbus0 #base SCSI code device ch0 #SCSI media changers device sd0 #SCSI disks device st0 #SCSI tapes device cd0 #SCSI CD-ROMs disk sd0 at scbus0 target 0 disk sd1 at scbus0 target 1 disk sd2 at scbus0 target 2 disk sd3 at scbus0 target 3 disk sd4 at scbus0 target 4 disk sd5 at scbus0 target 5 disk sd6 at scbus0 target 6 tape st0 at scbus0 target 0 tape st1 at scbus0 target 1 tape st2 at scbus0 target 2 tape st3 at scbus0 target 3 tape st4 at scbus0 target 4 tape st5 at scbus0 target 5 tape st6 at scbus0 target 6 device cd0 at scbus0 target 0 device cd1 at scbus0 target 1 device cd2 at scbus0 target 2 device cd3 at scbus0 target 3 device cd4 at scbus0 target 4 device cd5 at scbus0 target 5 device cd6 at scbus0 target 6 # SCSIDEBUG: When defined enables debugging macros # NO_SCSI_SENSE: When defined disables sense descriptions (about 4k) # SCSI_REPORT_GEOMETRY: Always report disk geometry at boot up instead # of only when booting verbosely. #options SCSIDEBUG #options NO_SCSI_SENSE options SCSI_REPORT_GEOMETRY ##################################################################### # MISCELLANEOUS DEVICES AND OPTIONS # # Of these, only the `log' device is truly mandatory.

There should be. # Micro Channel is not supported at all. # # Mandatory ISA devices: isa, sc, npx # controller isa0 # # Options for `isa': # # ALLOW_CONFLICT_DRQ suppresses the DMA conflict checks. This option is # included so that people with sound cards that support multiple emulations # can setup different sound drivers on the same DMA channel. There are no # other known uses for this option. # # ALLOW_CONFLICT_IOADDR suppresses the I/O address conflict checks, so # that the PS/2 mouse driver doesn't conflict with the console driver. # # ALLOW_CONFLICT_IRQ suppresses the interrupt line conflict checks, so # that multiple devices can share the same IRQ, provided that the # hardware supports it (it usually doesn't). # # ALLOW_CONFLICT_MEMADDR suppresses the memory address conflict checks. # This option is not known to be good for anything. # # AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A # interrupt controller. This saves about 1.25 usec for each interrupt. # No problems are known to be caused by this option. # # AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A # interrupt controller. This saves about 1.25 usec for each interrupt. # Automatic EOI is documented not to work for for the slave with the # original i8259A, but it works for some clones and some integrated # versions. # # BOUNCE_BUFFERS provides support for ISA DMA on machines with more # than 16 megabytes of memory. It doesn't hurt on other machines. # Some broken EISA and VLB hardware may need this, too. # # DUMMY_NOPS disables extra delays for some bus operations. The delays # are mostly for older systems and aren't used consistently. Probably # works OK on most EISA bus machines. # # TUNE_1542 enables the automatic ISA bus speed selection for the # Adaptec 1542 boards.
