91cdb9393a Changed delay mechanism to rely more on I/O spinning. If spinning on the
like this is bad news, it will have to be revised.
Shortened some verbose messages for when the kernel is loaded below 640k.
Updated version number.

f68251221d From Hellmuth Michaelis, reviewed by Bruce Evans: This enables
the keyboard clock rather than incorrectly disabling it.

7fb934835d make BOOTWAIT loopcount parameter available for tuning.
This changes nothing unless f.e. -DBOOTWAIT=0 or -DBOOTWAIT=640000 is used

0eadd3ea8c Touch the $Revision$ string to cause a cvs revision update of the boot
code (ie, should now print Revision 1.13).

6d2ef18502 Be paranoid about setting of %dl register for braindead BIOS's,
initializing it to 0 in the floppy boot case.  This allows my Toshiba
1910 laptop to finally boot, and may help out other machines cursed
with early Phoenix BIOS's as well.

2fdc4a4a0a This should fix up the absolute paths to /usr/mdec - just prepended
${DESTDIR} to all the right places (any reason why not?).

a94a714026 From Bruce:
*	If there is no 386BSD partition, initialize the label sector with
 *	LABELSECTOR instead of with garbage.
 *	Fixed reading of bad sector table.  It is at the end of the 'c'
 *	partition, which is not always at the end of the disk.

0dbe39ffd2 Change switch statement to two if statements. This saves 208 bytes in
the object file which is enough to bring the size down to the point
where the bootstrap fits into 15 sectors.

b2b233fcc4 Adding bootoption '-r' which is "use compiled in root". This allows me to
boot from a floppy and have root on wd2 for instance.

Subject: cache botch in bootstrap
Date: Sun, 20 Feb 94 18:14:35 +1100
The cache in the bootstrap loader didn't allow for the device changing.

This caused surprisingly little trouble - the cache is only for a single
track (or part of a track), and the first access to a new device is
always for an early sector, so there is no problem unless the last access
to the old device was for an early sector.  I saw the problem on a system
with BSD on wd1 and no label on wd0.  Everything worked if the the device
name wd(1,a) was specified before the default of wd(0,a) was tried, but
when the default was tried, it failed on the first sector because there
was no label, and then the first sector on wd0 was always used instead
of the first sector on wd1, so there was apparently no label on wd1
either.

b58557899d Deleted the private cleandir target. It didn't had a rule for the
obj symlink in it and the normal bsd.prog.mk cleandir target does
already the correct thing.

93f6cc5abd >From Charles Hannum
Change movl %es: -2(reg) to use a subl $2,reg when fixing up the IDT
entries for bdb.  This seems to be the best way to go.

Some day soon #ifdef BDB all of Bruces debugger code.

7b833e734d Removed all patch kit headers, sccsid and rcsid strings, put $Id$ in, some
minor cleanup.  Added $Id$ to files that did not have any version info, etc

3f11d4d9df Fixed the options hd(1,... to be more accurate (removed word options it
now reads:

printf("use hd(1,a)/386bsd to boot sd0 when wd0 is also installed\n");

I know the person wanted more explination, but there is little room in
the boot blocks for verbose text!

which drive he wants the root file system (A or B).

03aa455713 Remove the ``loader overlaps bss, kernel must bzero'' printf since that
is so often reported as an error condition when it is not.  We print the
size of things so for those who want to know if this happened they can
figure it out from the size information that is printed.

ae749d9344 New boot blocks, from Bruce Evans, and NetBSD fixes. Allows kernel to

etc etc etc. (I don't have much history on this, but then have been tested)
