This puppy is in good shape now.
It is a fully blown SCSI-driver, but it isn't a high performance one. It is
implemented entirely with polled I/O, and is intended to drive CD-ROM's, not
disks and tapes. It will run disks and tapes if asked to, but it isn't a
very good idea to do so. Transfer-rates max out at 600-700 kbyte/sec.
There is one problem: when write-requests get over 8192 bytes, the pseudo-DMA
stalls. This is only a problem if you dd(1) to a raw-device of some kind,
for mounting a disk it is ok. I have circumvented this by disabling the
pseudo-DMA in those cases.
It's very unlikely that I will spend more time on improving the performance
of this driver, it can do what I want it to now: install from a CD-ROM, and I
don't see any benefit in actually adding interrupts to the driver, considering
that performance never will be better than 700 kbyte/sec anyway.
You can install it under 1.1.5 too, by adding the lines to files.i386, your
config-file and copying pas.c and ic/ncr_5380.h over.
I will fix any bugs I can get a handle on.

otherwise the machine will overflow the stack in a recursive fault loop
(causing the machine to spontaneously reboot because of the stack fault
that ultimately happens).

(Eventually the code should be dynamically loadable.)
Also, allow for Pentium CPUs in GENERICBT kernels.
Add an `install' rule to Makefile.i386, which looks like this:
mv /kernel /kernel.old
install -c -m 555 -o root -g root -fschg kernel /
I'd like comments on whether or not you think it's a good idea to have
the kernel be immutable by default; I'm happy either way.

cd9660_readdir was incorrectly casting a pointer to the d_namlen field of a
struct dirent to a (u_short*) which caused the directory entries "." and ".."

if KERNEL is not defined. lib/msun/i387/*.S include asmacros.h to
get the definitions of ENTRY(), etc. This is bogus since asmacros.h
is only supposed to give definitions suitable for the kernel. The
current definitions for the kernel almost worked but are missing
the ".type" declarations. This caused the linker to print warnings
about doubtful relocations for almost anything linked to libm[sun].

the Mach/i386 version of the BSD/vax(?) <machine/psl.h>. The Mach

to something more recent than the ancient 1.2 release contained in
4.4. This code has the following advantages as compared to
previous versions (culled from the README file for the SunOS release):
- True multicast delivery
- Configurable rate-limiting of forwarded multicast traffic on each
physical interface or tunnel, using a token-bucket limiter.
- Simplistic classification of packets for prioritized dropping.
- Administrative scoping of multicast address ranges.
- Faster detection of hosts leaving groups.
- Support for multicast traceroute (code not yet available).
- Support for RSVP, the Resource Reservation Protocol.
What still needs to be done:
- The multicast forwarder needs testing.
- The multicast routing daemon needs to be ported.
- Network interface drivers need to have the `#ifdef MULTICAST' goop ripped
out of them.
- The IGMP code should probably be bogon-tested.
Some notes about the porting process:
In some cases, the Berkeley people decided to incorporate functionality from
later releases of the multicast code, but then had to do things differently.
As a result, if you look at Deering's patches, and then look at
our code, it is not always obvious whether the patch even applies. Let
the reader beware.
I ran ip_mroute.c through several passes of `unifdef' to get rid of
useless grot, and to permanently enable the RSVP support, which we will
include as standard.

Add initialization to the if_ie driver for the Micom Interlan NI5210 card.
This is a very old 82586 based card with only 8Kb or 16Kb on board memory.
Also only 8-bit wide instead of 16-bit like the AT& or 3COM card.
Warning: this thing is only tested so far that it detects all bits
correctly but is not yet on an ethernet. Will do that tomorrow.

Theo de Raadt, Charles, and Michael V. may have contributed to it.

actually have a printer connected or online:
- MAKEDEV: remove all signs of lpa
add lpctl? devices (minor # = unit + 128)
- usr.sbin/Makefile add lptcontrol
- sys/i386/isa/lpt.c implement the LP_BYPASS flag: when a unit is
opened with this flag set, the printer is
not primed, and no check is made to see that
the printer is online. This can only be used
to pass ioctls. (giving us /dev/lpctl?)
- lptcontrol.c use /dev/lpctl? (LP_BYPASS)
-f flag removed, -u flag added
- lptcontrol.8 document changes in lptcontrol
