Instead, you should start from GENERIC, and add options from 9# this file as required. 10# 11 12# 13# This directive is mandatory; it defines the architecture to be 14# configured for; in this case, the 386 family. You must also specify 15# at least one CPU (the one you intend to run on); deleting the 16# specification for CPUs you don't need to use may make parts of the 17# system run faster 18# 19machine "i386" 20cpu "I386_CPU" 21cpu "I486_CPU" 22cpu "I586_CPU" # a/k/a Pentium(tm) 23 24# 25# This is the ``identification'' of the kernel.

The host adapters are listed in the ISA and PCI 240# device configuration sections below. 241# 242# Note that, unlike most similar systems, the FreeBSD SCSI system 243# does not wire a particular device unit number to any specific 244# SCSI bus unit number. Rather, unit numbers are assigned in the 245# order that the devices are found on the SCSI bus. (This means that 246# if you remove a disk drive, you may have to rewrite your /etc/fstab 247# file.) It is expected that this will change for FreeBSD 2.1. 248# 249controller scbus0 #base SCSI code 250device ch0 #SCSI media changers 251device sd0 #SCSI disks 252device sd1 253device sd2 254device sd3 255device st0 #SCSI tapes 256device st1 257device uk0 #unknown scsi devices 258 259# 260# The `cd' (SCSI read-only removable disk) driver is special in that 261# the code dynamically allocates more units as they are required, with 262# no limit (other than memory) to the number available. 263device cd0 #SCSI CD-ROMs 264 265 266##################################################################### 267# MISCELLANEOUS DEVICES AND OPTIONS 268 269# 270# Of these, only the `log' device is truly mandatory.

There should be. 288# Micro Channel is not supported at all. 289 290# 291# Mandatory ISA devices: isa, sc, npx 292# 293controller isa0 294 295# 296# Options for `isa': 297# 298# ALLOW_CONFLICT_DRQ suppresses the DMA conflict checks. This option is 299# not known to be good for anything. 300# 301# ALLOW_CONFLICT_IOADDR suppresses the I/O address conflict checks, so 302# that the PS/2 mouse driver doesn't conflict with the console driver. 303# 304# ALLOW_CONFLICT_IRQ suppresses the interrupt line conflict checks, so 305# that multiple devices can share the same IRQ, provided that the 306# hardware supports it (it usually doesn't). 307# 308# ALLOW_CONFLICT_MEMADDR suppresses the memory address conflict checks. 309# This option is not known to be good for anything. 310# 311# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A 312# interrupt controller. This saves about 1.25 usec for each interrupt. 313# No problems are known to be caused by this option. 314# 315# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A 316# interrupt controller. This saves about 1.25 usec for each interrupt. 317# Automatic EOI is documented not to work for for the slave with the 318# original i8259A, but it works for some clones and some integrated 319# versions. 320# 321# BOUNCE_BUFFERS provides support for ISA DMA on machines with more 322# than 16 megabytes of memory. It doesn't hurt on other machines. 323# Some broken EISA and VLB hardware may need this, too. 324# 325# DISKSLICE provides support for slicing up a disk into virtual disks. 326# It isn't really ISA-specific, but the on-disk slice table is currently 327# required to be a DOS partition table. 328# 329# DUMMY_NOPS disables extra delays for some bus operations. The delays 330# are mostly for older systems and aren't used consistently. Probably 331# works OK on most EISA bus machines. 332# 333# TUNE_1542 enables the automatic ISA bus speed selection for the 334# Adaptec 1542 boards. Does not work for all boards, use it with caution. 335# 336#options ALLOW_CONFLICT_DRQ 337#options ALLOW_CONFLICT_IOADDR 338#options ALLOW_CONFLICT_IRQ 339#options ALLOW_CONFLICT_MEMADDR 340options "AUTO_EOI_1" 341#options "AUTO_EOI_2" 342options BOUNCE_BUFFERS 343options DISKSLICE 344#options DUMMY_NOPS 345#options TUNE_1542 346 347device sc0 at isa? port "IO_KBD" tty irq 1 vector scintr 348 349# 350# Options for `sc': 351# 352# NCONS specifies the number of virtual consoles.
