Sure, OK. Here's the last one I've been using, before I did any editing. I have five scsi devices. The disks are wired down, the cd's are not wired down here, but they show up on ahc1 targets 5 & 6 (show them floating, for more variety in the example). ---------------------------------------------------------------------------- machine i386 cpu I586_CPU cpu I686_CPU ident CH maxusers 64 # Create a SMP capable kernel (mandatory options): options SMP # Symmetric MultiProcessor Kernel options APIC_IO # Symmetric (APIC) I/O # Optional, these are the defaults: options NCPU=2 # number of CPUs options NBUS=4 # number of busses options NAPIC=1 # number of IO APICs options NINTR=24 # number of INTs options SYSVSHM options SYSVSEM options INCLUDE_CONFIG_FILE options SYSVMSG options MSGBUF_SIZE=40960 options NETATALK #Appletalk communications protocols options NETGRAPH #netgraph(4) system options P1003_1B options _KPOSIX_PRIORITY_SCHEDULING options _KPOSIX_VERSION=199309L # Lets always enable the kernel debugger for SMP. options DDB options GPL_MATH_EMULATE #Support for x87 emulation via options INET #InterNETworking options INET6 #IPv6 communications protocols options FFS_ROOT options FFS #Berkeley Fast Filesystem options NFS #Network Filesystem options MSDOSFS #MSDOS Filesystem options CD9660 #ISO 9660 Filesystem options PROCFS #Process filesystem options COMPAT_43 #Compatible with BSD 4.3 [KEEP THIS!] options SCSI_DELAY=8000 #Be pessimistic about Joe SCSI device options UCONSOLE #Allow users to grab the console options USERCONFIG #boot -c editor options VISUAL_USERCONFIG #visual boot -c editor options SOFTUPDATES options VESA # needs VM86 defined too!! options COMPAT_LINUX # If you see the "calcru: negative time of %ld usec for pid %d (%s)\n" # message you probably have some broken sw/hw which disables interrupts # for too long.
