The only place I found with a printf("status %x") is in /sys/i386/isa/lpt.c,
and looks much like a left-over debugging printout...
And it was... I changed it to an lprintf (which is defined if debuggin is on)

Added STRIP=, DBSYM=, and LOAD_ADDRESS?=
Now use LOAD_ADDRESS for linking kernel and for dbsym, added strip -x to
cut kernel size.
Added machde.o: dependency, this will be needed in the future, and for
now it does not hurt anyone.
Cleaned out conf.o: dependency, mkdep does the right things. Same for
param.c:
This is really a Merge in of NetBSD's Makefile.i386, here is the relevant

This will allow you to compile and run a freebsd kernel with shared
memory support. I haven't tested the shm*() calls yet.
You run out of page table descriptors if you specify 4Mb of sharable
memory (SHMMAXPGS=1024). I don't know what the limit is, but
SHMMAXPGS=64 works. Rich

I think removing FINDWORK would make things clearer.
Nothing much is going to start work on the next item. However, it is
pointless to continue processing the queue for the same unready drive.
Aborting all reads and trying harder to perform all writes would be
better.

The fd driver reported the wrong cylinder/head/sector numbers after an
error (ST3 is only valid after a sense-drive command), and didn't report
fs block numbers (diskerr was not used).
There was an old problem with writes to block fd devices. Try this:
1. write protect floppy in fd0.
2. tar cf /dev/fd0a /dev/null. Repeat a few times. Later writes tend to
terminate earlier.
3. un-write protect floppy.
4. repeat step 2. The writes tend to return 0, 2048, 4096, ... and then
succeed.
This was caused by a bug in vfs__bios.c. (The bug is fixed in NetBSD's
vfs_bio.c.) fd.c sets bp->b_resid to nonzero after an error. vfs__bios.c
was not initializing bp->b_resid. This causes some writes to terminate
early (e.g., writes to block devices; see spec_write()).
Related funnies:
1. Nothing tries to write the residual bytes.
2. The wd driver sets bp->b_resid to 0 after an error, so there's no
way anything else could write the residual bytes.
3. I use the block fd device for tar because the raw device seemed to
have more bugs long ago, and because it ought to be able to handle
buffering more transparently (I don't want to have to know the
device size). But spec_write() always uses the size BLKDEV_IOSIZE
== 2048 which is too small. For disks it should use the size of
one track (rounded down to meet the next track boundary or the i/o
size). Here it would help if the DIOCGPART ioctl worked. But
DIOCGPART is not implemented for floppies, and the disk size is
ignored except for partitions of type FS_BSDFFS.

quite and works correctly. This is derived from notes in Bruce Evans

>Subject: fixes for fd driver
I think I've fixed some bugs in the 0.2.4 fd driver.
1. The main cause of hangs was that there was no timeout for seeks. So
attempting i/o with no floppy in the drive hung iff a seek was required.
2. Opens of unattached drives were allowed. The kernel usually paniced
soon after due to a bad pointer.
3. Some timeout functions ran at splclock() instead of splbio(). This
may not have mattered.
4. The state machine was left in a funny state after a timeout.
5. Some function headers were new-style.
6. I picked up some code posted the other day to implement label ioctls.
Now `disklabel fd0' works. See a comment for how to modify conf.c.
>Subject: Bad bug in kbdtables.h [FreeBSD]
I found a bug in /sys/i386/isa/kbdtables.h which contain the
different keyboard layouts for syscons. This regards all tables exept
the Danish and US. When compiling the kernel with any other keymapping
than Danish or none at all (US), you get an error that 'key_map' is undefined.
This is because there is a typo in the name of the struct containing
the tables, keymap intead of key_map.
That is because TIOCMGET was broken. Yes...this is known for some time
and no, we (Bruce and me) never posted it. Why? Simply because we choose
to post fixes when we fixed most of the bugs.
Anyway..now that the slip problems are coming, here is a fix for
correct TIOCMGET behaviour.

Note: this should be tested first (Rich?). Tested by rgrimes
1) fixed 3c503 lock-up if the thinwire cable was disconnected at boot time
2) 8013EBT boards now work (quite well!) in 16bit/16k mode
3) ED_NO_DOUBLE_BUFFERING flag now works
4) slightly higer performance (about 3%) with 16bit WD/SMC boards
5) support for WD8013WC (10BaseT) boards
Additionally, the probe code has been reorganized to be much cleaner. This
revision of the driver is 1.25. The release notes have been updated as well.
going to panic shortly after this anyway. Destroys less state, and
keeps the machine from waiting for someone to smash the return key
a few times before it panics!
Subject: Re: Some small errors in GAMMA
4. Move printf("\n"); at line 491 in "/sys/i386/isa/sio.c" to after
COM_MULTIPORT block at line 512.
From rgrimes:
The above would cause the word (multiport) with out a new line to
appear after the uart type message if you had COM_MULTIPORT enabled.
Added support of DONET({IMP,NS,ISO}) so you can now compile with options
NS and ISO, still missing some IMP code, but since the imp is old and
gone I doubt this will ever be used.
Subject: More information on "netstat -r
Date: Mon, 7 Jun 1993 11:57:33 +0100
Gentlemen,
I have been trying for some time now to get "netstat -r"
working from the 0.2.2 patchkit. I have the following solution to the
bug.
The symbol _radix_node_head needs to be added to the symbols.raw file
to enable the new routing table access. If this symbol is not present
then the old system us used which results in no routes being given. I
don't think that this justifies a patch in its own right but perhaps
could be added to a related patch sometime..

This fixes several problems.
It has almost everything that is in the FreeBSD version of Aug 22.
It is missing the bug for 2 drives and still prints <> around the
drive type. It handles BADEND144 less verbosely. It does wdgetctlr()
somewhat differently from NetBSD/FreeBSD.

Fixed printf's to be correct, since Bruce used the old ones. This driver
still prints phantom wd1's on some Maxtor and other IDE drives, I have
a patch I am sending to Bruce for checking.
wd80x3 class boards can be configured to the GENERIC kernels.
Entry was:
device ed0 at isa? port 0x280 net irq 9 iomem 0xd0000 vector edintr
Is now:
device ed0 at isa? port 0x280 net irq 5 iomem 0xd8000 vector edintr
FP and we try to call the emulator when it is not compiled in.
Removed the #if defined(i486) || defined(i387) that use to call the
panic if we did not have a math emulator.
Removed an extranious include of i386/i386/math_emu.h from math_emulate.c.
