#### System options that are the same for all ports

## Root device configuration: change the ?'s if you are going to use a
## nonstandard root partition (other than where the kernel is booted from)
## and/or nonstandard root type (not ffs or nfs).  Normally this can be
## automagically determined at boot time.

config		netbsd	root on ? type ?

## System call tracing (see ktrace(1)).
#options 	KTRACE

## Collect statistics on kernel malloc's and free's.  This does have a
## significant performance hit on slower machines, so it is intended for
## diagnostic use only.
#options 	KMEMSTATS

## System V compatible IPC subsystem.  (msgctl(2), semctl(2), and shmctl(2))
#options 	SYSVMSG		# System V message queues
#options 	SYSVSEM		# System V semaphores
#options 	SYSVSHM		# System V shared memory

options 	USERCONF	# userconf(4) support
options 	PIPE_SOCKETPAIR		# smaller, but slower pipe(2)
#options 	SYSCTL_INCLUDE_DESCR	# Include sysctl descriptions in kernel

## NFS boot options; tries DHCP/BOOTP then BOOTPARAM
options 	NFS_BOOT_BOOTPARAM
#options 	NFS_BOOT_BOOTP
options 	NFS_BOOT_DHCP

#### Debugging options

## The DDB in-kernel debugger runs at panic (unless DDB_ONPANIC=0), or at
## serial console break or keyboard reset, where the PROM would normally
## intercept.  DDB_HISTORY_SIZE adds up/down arrow command history.
#options 	DDB			# kernel dynamic debugger
#options 	DDB_HISTORY_SIZE=100	# enable history editing in DDB
#options 	DDB_ONPANIC=1		# see also sysctl(8): `ddb.onpanic'

## You may also use gdb, on another computer connected to this machine over
## a serial port.  Both KGDB_DEV and KGDB_DEVRATE should be specified;
## KGDB_DEV is a dev_t encoded device number of the serial port to use.
## (0xc01 = ttya, 0xc02 = ttyb.)
#options 	KGDB			# support for kernel gdb
#options 	KGDB_DEV=0xc01		# kgdb device number (this is `ttyb')
#options 	KGDB_DEVRATE=38400	# baud rate


## Compile the kernel with debugging symbols (`netbsd.gdb' is the debug file),
## such that gdb(1) can be used on a kernel coredump.

#makeoptions	DEBUG="-g"


## Adds code to the kernel that does internal consistency checks, and will
## cause the kernel to panic if corruption of internal data structures
## is detected.
#options 	DIAGNOSTIC	# extra kernel sanity checking

## Enable (possibly expensive) debugging code that may also display messages
## on the system console
#options 	DEBUG

#options 	MIIVERBOSE	# verbose PHY autoconfig messages

## Make SCSI error messages more verbose when explaining their meanings.
#options 	SCSIVERBOSE

## `INSECURE' turns off the kernel security level (securelevel = 0 always).
## This allows writing to /dev/mem, loading kernel modules while multi-user,
## and other insecurities good only for development work.  Do not use this
## option on a production machine.
options 	INSECURE

## `FDSCRIPTS' allows non-readable but executable scripts by providing a
## pre-opened opaque file to the script interpreter.  `SETUIDSCRIPTS',
## which implies FDSCRIPTS, allows scripts to be set-user-id using the same
## opaque file mechanism.  Perl calls this "secure setuid scripts."

#options 	FDSCRIPTS
#options 	SETUIDSCRIPTS

## Options for compatibility with previous releases foreign system binaries.
## In the cases of COMPAT_SUNOS and COMPAT_SVR4, you may need to set up
## additional user-level utilities or system configuration files. See
## compat_sunos(8) and compat_svr4(8).

## The following flags may be set for the NCR53c94 based esp driver:
##	bits 0-7:  disable disconnect/reselect for the corresponding target
##	bits 8-15: disable synchronous negotiation for target [bit-8]

## sun4/300, sun4c, sun4m on-board SCSI, and FSBE/S SBus SCSI cards.
## Both `dma' and `esp' are needed in all cases.
## Two kinds of additional SBus SCSI interfaces are available.  One uses
## "esp at sbus" like the sun4c on-board; the other uses "esp at dma".

## sun4/300 SCSI - an NCR53c94 or equivalent behind

## NCR5380-based "Sun SCSI 3" VME SCSI controller.
## This driver has several flags which may be enabled by OR'ing
## the values and using the "flags" directive.
## Valid flags are:
##
##	0x01		Use DMA (may be polled)
##	0x02		Use DMA completion interrupts
##	0x04		Allow disconnect/reselect
##
## E.g. the following would enable DMA, interrupts, and reselect:
## si0	at vme0 addr 0x200000 irq 3 vect 0x40 flags 0x07
##
## By default, DMA is enabled in the driver.

si0	at vme0 addr 0x200000 irq 2 vect 0x40
scsibus* at si?

## NCR5380-based "SCSI Weird" on-board SCSI interface found
## on sun4/100 systems.  The flags are the same as the "si"
## controller.  Note, while DMA is enabled by default, only
## polled DMA works at this time, and reselects do not work
## on this particular controller.
