The generic kernel does not include all options, subsystems 7# and device drivers, but should be useful for most applications. 8# 9# The machine description file can be customised for your specific 10# machine to reduce the kernel size and improve its performance. 11# 12# For further information on compiling NetBSD kernels, see the config(8) 13# man page. 14# 15# For further information on hardware support for this architecture, see 16# the intro(4) man page. For further information about kernel options 17# for this architecture, see the options(4) man page. For an explanation 18# of each device driver in this file see the section 4 man page for the 19# device. 20 21include "arch/amd64/conf/std.amd64" 22 23#options INCLUDE_CONFIG_FILE # embed config file in kernel binary 24 25#ident "GENERIC-$Revision: 1.211 $" 26 27maxusers 64 # estimated number of users 28 29# delay between "rebooting ..." message and hardware reset, in milliseconds 30#options CPURESET_DELAY=2000 31 32# This option allows you to force a serial console at the specified 33# I/O address. see console(4) for details. 34#options CONSDEVNAME="\"com\"",CONADDR=0x2f8,CONSPEED=57600 35# you don't want the option below ON iff you are using the 36# serial console option of the new boot strap code. 37#options CONS_OVERRIDE # Always use above! independent of boot info 38 39# The following options override the memory sizes passed in from the boot 40# block.
