but if not then try to boot "netbsd", "netbsd.bak", "netbsd.old", and

is exhausted.
machines with old firmware which doesn't pass it in the boot device

structure to allow netboot information to be hard-coded in network
boot blocks, so that they can be made to work even on systems with
firmware which doesn't support the new "ethernet address in boot device"
convention.
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.
add SysV Shared Memory support, since it can be used by the X server.
add 'ppp' to the list of pseudo-devices, and sort the list to recover
from the renaming of 'rd' to 'md'.
other slight cleanups.
__builtin_classify_type() into harmless values, so that lint doesn't
get confused, think they're real functions, and that they're being
invoked in the wrong ways.
using __weak_alias in libc, __indr_reference should probably be defined
to do nothing (but defined, so that duplicate functions/variables aren't
compiled). However, when not using __weak_alias, __indr_reference causes
them to be omitted completely, which is a lose. So, until weak aliases
are going to be used, don't define __weak_alias or __indr_reference.
for by crt0. Actually clear a1 and a2, because unless a shared loader (i.e.
_not_ the kernel) set them when invoking crt0, they should be zero, and
the kernel DEBUG code wouldn't necessarily have them be. Pass a pointer
to the proc's ps_strings structure in a3.
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:
Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.
Lets users over-ride with makeoptions COPTS="..." in kernel config files.
Leave `mandatory' flags (like -msoft-float which on m68k enforces no
FP in kernel) in CFLAGS.

the chipset space init functions multiple times, since that would clobber
extent allocations made between the two calls. Also, deal with the
fact that the APECS and LCA no longer shared common chipset functions.
the same things, but the extent maps have to be managed differently,
since the two chipsets provide different memory and I/O region mapping
possibilities.
and PC-ish keyboard controller. (Actually, on alphas, the built-in PPI
(in the SIO) appears to be a lobotomized version of the original, but
i'd not call that a bad thing.) This driver should eventually handle all
speaker tone requests and keyboard commands, but for now it just maps
the relevant ports and passes them on to the keyboard and mouse drivers,
which are now its children (rather than children of ISA).
