The generic kernel on NetBSD/alpha does enough to get booted, 7# etc., but not much more. For a more complete kernel see the ALPHA 8# machine description file. 9# 10# The machine description file can be customised for your specific 11# machine to reduce the kernel size and improve its performance. 12# 13# For further information on compiling NetBSD kernels, see the config(8) 14# man page. 15# 16# For further information on hardware support for this architecture, see 17# the intro(4) man page. For further information about kernel options 18# for this architecture, see the options(4) man page. For an explanation 19# of each device driver in this file see the section 4 man page for the 20# device. 21 22# If you add stuff to this, please add it to the ALPHA configuration, too. 23 24include "arch/alpha/conf/std.alpha" 25 26options INCLUDE_CONFIG_FILE # embed config file in kernel binary 27 28#ident "GENERIC-$Revision: 1.228 $" 29 30maxusers 32 31 32# CPU Support 33options DEC_2000_300 # "Jensen": 2000/300 (DECpc AXP 150) 34options DEC_2100_A50 # Avanti etc: AlphaStation 400, 200, etc. 35options DEC_2100_A500 # Sable: AlphaServer 2100 36options DEC_2100A_A500 # Lynx: AlphaServer 2100A 37options DEC_3000_500 # Flamingo etc: 3000/[4-9]00* 38options DEC_3000_300 # Pelican etc: 3000/300* 39options DEC_AXPPCI_33 # NoName: AXPpci33, etc. 40options DEC_EB164 # EB164: AlphaPC 164 41options DEC_EB64PLUS # EB64+: AlphaPC 64, etc. 42options DEC_KN20AA # KN20AA: AlphaStation 500 and 600 43options DEC_KN8AE # KN8AE: AlphaServer 8200 and 8400 44options DEC_KN300 # KN300: AlphaServer 4100 and 1200 45options DEC_550 # Miata: Digital Personal Workstation 46options DEC_1000 # Mikasa etc: Digital AlphaServer 1000 47options DEC_1000A # Corelle etc: Digital AlphaServer 800/1000A 48options DEC_ALPHABOOK1 # AlphaBook1: Tadpole/DEC AlphaBook 49options DEC_EB66 # EB66: 21066 Evaluation Board 50options DEC_6600 # EV6: 264DP OEM Board 51options API_UP1000 # EV6: Alpha Processor, Inc.
