463d8c14c4 Autoconf is the one to realize that we are booted disk-less and start the
ball rolling.  locore is just moving some data from the boot-program.

de23562289 NFS-diskless works. Look in sys/i386/boot/netboot for some of the
explanation.  More doc needed, but not hard to do, if you want to.

A big hand to Martin Renters for the netboot program !

Anybody want to compete on who can "make world" in the shortest
amount of time ?  I have 127 i486DX2/66 and 5 P60's I can use
now.  And 3 times 66 Gb file servers to support it... :->

Anyway, NFS will be standard in the GENERIC kernel now, so that
people can use the bin-tarball to set up shop.

c6bdff3132 Make the diagnostics a little more useful.
A word of wisdom, don't do this:

|	cd /usr/bin
|	for i in *
|	do
|		cp $i /tmp/a
|		gzip -9 < /tmp/a > $i
|	done

It will compress files with multiple links several times.  do it this way:

|	cd /usr/bin
|	for i in *
|	do
|		gunzip -f < $i > /tmp/a
|		gzip -9 < /tmp/a > $i
|	done

ab856e27b3 I belive imgact_gzip is finally reentrant. It is also a whole lot more
readable.

inflate is now much more general, and is there if anybody feels like making
a uncompressing filesystem or something like that (hint hint !)

dd9d06bd3f Restrict fs_maxfilesize to 2^40, and check against this in ffs_truncate().
This is part of a bug fix from Kirk McKusick to work around problems in FFS
related to the blkno of a 64bit offset not fitting into an int. Note the
proper solution would be to deal with 64bit block numbers, but doing this
would require sweeping changes; some other day perhaps.

e8b2d4b14c Various changes to allow operation without any swapspace configured. Note
that this is intended for use only in floppy situations and is done at
the sacrifice of performance in that case (in ther words, this is not the
best solution, but works okay for this exceptional situation).

e0b2523cc3 From: hosokawa@mt.cs.keio.ac.jp (HOSOKAWA Tatsumi)
One of the alpha testers (ETO, Toshihisa <eto@osl.fujitsu.co.jp>)
of my APM driver sent me a very small patch to if_ze.c for using IBM
PCMCIA Ethernet card II.  There are only a few difference between
Ethernet card I and II.  So we can use them both with this patch.  It
also includes a patch for PCIC of ThinkPad 230Cs (As long as I
remember, this model is available in Japan only. But it is very
popular subnote in Japan).

945b826761 Checking for timeout at several critical calls to ``out_fdc()'' now,
so i hope i've finally removed all the occasions where the driver
got stuck when there's no floppy in the drive.
Also attemmpting to  omit the error mesage for ``recalib failed''
for the first time, since people tend to be confused about this.

2cf5e51b10 ATTENTION!
From now on, >all< swapdevices must be activated with "swapon".

If you havn't got it, add this line to /etc/fstab:
	/dev/wd0b	none	swap	sw	0 0
ne sec

Reason:
We want our GENERIC* kernels to have a large selection of swap-devices, but
on the other hand, we don't want to use a wd0b as swap when we boot of a
floppy.  This way, we will never use a unexpected swapdevice.  Nothing else
has changed.

942fc20db7 Don't check for IRQ conflicts before probing the device, so that
drivers have a chance to change their IRQ before it is checked.
This was implemented in revision 1.21 and broken in revision 1.26.
Drivers that can change their IRQ should probably be configured
with "irq ?".
