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.

Update the if_ep driver for the 3C579 and bring over some of the

This is not complete: the detection of the irq in the eisa does not
work and sometimes the reset for the 3C509 in ISA in an EISA bus system
don't work ( Need a hard reset to be found again == reset knob).
DIOCGDINFO, DIOCGPART, DIOCWDINFO, DIOCSDINFO, CDIOCPLAYMSF, CDIOCRESET,
CDIOCEJECT.
CDIOCPLAYBLOCKS removed (old implementation completely wrong and I don't
know how to implement it correctly).
All routines now detects media change correctly.
DELAY_GETREPLAY increased for long time access from first track
to last.
mcd_waitrdy() now use MIN_DELAY=15 as minimal delay which independs
of machine speed.
mcd_doread() now uses real status (old code uses obsoleted soft copy of it).
clear XBSY on error in mcd_doread()
mcd_statrt(): add missing splx(s), cause dead hang with unmatched slpbio()
optimize mcd_doread(), don't set CD mode each time, keep soft copy of mode.
call getdisklabel() _after_ mcdsize() for proper sizes
mcdopen(): old code forget to set MCDREADRAW in flags when open RAW
partition, doread check it for setting RAW CD mode.
Do nothing on stray interrupt (which sometimes occurse, because driver
read data block too slow, DOS driver use 'insb' here). Old stray code
cause timeouts.
Read toc entries code rewritten to return many requested entries
(as supposed) instead of one entry with incorrect structure.
CMDREAD2 requests covered with disable_intr()/enable_intr()
(from DOS driver)
Read junk code added after read block code in doread (from DOS driver)
mcd_read_toc() code fixed to read all needed entries, old code cause
some audio tracks is not played.
mcd_playtracks() code fixed to proper check valid track range.
New binary read modes implemented (from DOS driver).

bogus dependency was used for machdep.c and there was never anything
special about the others.
Add locore.s, but commented out. It's still special.
Remove com.c and lpa.c.
SYSTEM_OBS. They are now normal objects.
Remove stale dependencies for the above now-normal objects and for
locore.o and generate dependencies using mkdep. Config doesn't
generate lists of assembler source files so the lists to be mkdep'ed
have to be given explictly. Only the standard *.s files are given,

would be handled right if config put them in CFILES.
Don't define NPX. It was replaced by NNPX > 0 years ago.
Define LOAD_ADDRESS in COPTS so that compiling machdep.c isn't a special

Moving around the dependencies exposed a bug in make. It doesn't

Several examples of connection initiation follow. Although these
examples do not show connection synchronization using data-carrying
segments, this is perfectly legitimate, so long as the receiving TCP

connection reaches the ESTABLISHED state).

the code.
Merged changes from 2.0 version (revisions 1.46-1.50) by hand.
Finished conversion to clists: removed flush of tty output buffer
in comflush() (most writes were truncated to 256 bytes) and restored
bypass of ttyinput() in siopoll().
Finished conversion to 2.0 types - more void *'s, less caddr_t's,
less casts, no Dev_t's.
Only these things are seriously broken now compared with 1.1.5:
waiting for output complete is impossible so ttywait() can deadlock;
sioclose() isn't called enough so sioopen() sometimes returns EBUSY
unnecessarily; input flow control is not implemented.

forgot to declare them as extern and gcc-2.6.0 treats "extern int x[];"
slightly different from "int x[];" (this is probably a bug). The new
versions will cause RR warnings from gcc-2.4.5 because it does not
understand that the second declaration in "extern int x[]; int x[1];"
is not redundant. The variables don't actually need to be declared
in a header file because they are used in only one C source file and
one assembler source file, but I want all public variables and
comments about them to be findable by grepping *.h.

2) Replaced list of boot files with /kernel
3) Changed disklabel use in Makefile to conform to 4.4
4) Added size command in Makefile to get close estimate of bootblock

overestimated since a.out header subsequently gets stripped.

Hack is to define RCSID() to null macro so that new msun stuff

to talk about what our RCSID story is supposed to be. We talked about
supporting RCSID() one day, and everyone seemed to like the idea
reasonably well of making it a macro you could just no-op this way,
but we never did anything. Now I see that JTCs code has it and I'm
loath to remove it or do anything until we've discussed it some more.
Well, so how about it? What's our story vis-a-vis RCSID() going to

ALLOW_CONFLICT_IRQ is not supported. IRQ conflict checking is

o Prepare to register interrupt handlers as fast.
/usr/src/sys/i386/isa/vector.s:
o Generate entry code for 16 fast interrupt handlers and 16 normal
interrupt handlers. Changed some constants to variables:
# $unit is now intr_unit[intr]. Type is int. Someday it should
be a cookie suitable for the handler (e.g., a struct com_s for
sio).
# $handler is now intr_handler[intr].
# intrcnt_actv[id_num] is now *intr_countp[intr]. The indirection
is required to get a contiguous range of counters for vmstat
and so that the drivers depend more in the driver than on the
interrupt number (drivers could take turns using an interrupt
and the counts would remain correct). There is a separate
counter for each device and for each stray interrupt. In
1.1.5, stray interrupt 7 clobbers the count for device 7 or
something worse if there is no device 7 :-(.
# mask is now intr_mask[intr] (was already indirect).
o Entry points are now _XintrI and _XfastintrI (I = intr = 0-15),
not _VdevU (U = unit).
o Removed BUILD_VECTORS stuff. There's a trace of it left for
the string table for vmstat but config now generates the
string in one piece because nothing more is required.
o Removed old handling of stray interrupts and older comments
about it.

Added my if_lp TCP/IP driver to lpt.c.
I have (surprise) not been able to test it on a 2.0 machine yet. Connect the
machines with a parallel "lap-link" cable, and get rates from 35 kbyte/sec
up to 75 kbyte/sec. (when ftp'ing foo: dev/zero -> bar:/dev/null).
The same lpt.c file should compile under 1.1.5.1 without problems.
I think we should promote this feature when we dump 2.0 on the expectant
public, because it provides a cheap and efficient way to move data to and
from notebooks &c. It is not a replacement for ethernet, but a cheap
substitute sometimes.
