This should NOT go into 2.0.5 /phk
Support disk slices. This involves mainly replacing inline code with
function calls. Support for ST506 drives is temporarily broken since
the `setgeom' arg to dsopen() is not implemented completely enough to
use. The `setgeom' arg will go away and ST506 drives will be supported
in another way. A large amount of dead code is left in wdopen() as a
reminder of the problems here.
Close the device in wdsize(). Open tracking was broken on all drives
with a swap device.
Remove support for soft write protection. There are no ioctls to set
it. It was used to disable writing to unlabelled disks, but we want
to support writing to foreign partitions on unlabeled disks.
Use generic dkbad routines to do about 2/3 of the work for supporting
bad144.
Improve disk statistics: estimate 4MB/sec instead of 8MB/sec for
the transfer rate (ISA max is 4MB/sec, old IDE max is 3.3MB/sec);
fix dk_xfer[] (it counted sectors, not transfers); keep the estimate
dk_seek[] = dk_xfer[] (was sectors, is now transfers); only count
words actually transferred (the count is still too high after a
failed write and after retries). Remove wdxfer[].
Fix indentation in wdattach(). Fix resulting botched printing of the
disk size for ST506 drives. Print the disk geometry less cryptically.
o Fix the keyboard probe to properly wait for the ready bit before
sending a command to the keyboard controller. This should avoid the
problems some people are experiencing where the boot blocks hang the
system during keyboard probe. (It does solve it for me.)
o Fix a bug that effectively prevented the boot blocks from ever
passing control to the serial console. [while(--retries) instead of
while(retries--)]
o Gratuitously reduced the keyboard probe timeout from 500 to 5
seconds. :)
o Introduced a new option ``FORCE_COMCONSOLE'' as a commented-out
example in the Makefile, to force the usage of a serial console
regardless of a keyboard being connected or not.
o Moved all external declarations to boot.h, declared all functions
there, and ANSIfied all function declarations/definitions.
(printf() remains bogus, however -- i'm too lazy to fix this.)
We're in the ninetees, dunno why we should still support compilers
from the 70's.
of the plus or minus lists at all, reject him. This lets you create
a +@netgroup list of users that you want to admit and reject everybody
else. If you end your +@netgroup list with the wildcard line
(+:::::::::) then you'll have a +@netgroup list that remaps the
specified people but leaves people not in any netgroup unaffected.
and #if defined (I586_CPU) thingies into identifycpu() so that we only
compile in what's actually needed for a given CPU. So far as I can tell,
none of my 386 machines generate a cpu_vendor code, so I made the extra vendor
and feature line conditional on I486_CPU and I586_CPU. (Otherwise we
print out a blank line which looks silly.)
at least one user out there who's system won't autoboot from the
serial console because of what sounds like 'phantom keystrokes'
making the timeout timer trip. I've tried to solve this by
adding an extra call to init_serial() right before the 'Boot:'
prompt is printed (done only if RB_SERIAL is set) to hopefully
make sure that the input buffer is clear. Unfortunately, the fellow
is in Germany and I haven't heard back from him yet. I haven't
been able to duplicate this problem on my hardware, so this is
a stab in the dark. At the very least, it shouldn't hurt anything.
kernels with 'options I586_CPU.'
The declaration for pentium_mhz is hidden inside an #ifdef I586_CPU,
but machdep.c refers to it whether I586_CPU is defined or not. This
temporary hack puts the offending code inside an #ifdef I586_CPU as
well so that a kernel without it will successfully compile.
I must emphasize the word 'temporary:' somebody needs to seriously
beat on the identifycpu() function with an #ifdef stick so that
I386_CPU, I486_CPU and I586_CPU will do the right things.
