during phk's staticize/cleanup commits. pstat needs it, the MAXCONS
option is not visible anywhere else, and pstat uses it to find the bounds
of the sccons[MAXCONS] array, which varies.
. preserve a multi-char sequence in a small static buffer inside
pccngetc(), so it won't be clobbered later (used to happen when
breaking into DDB user Ctrl-Alt-ESC), and
. simplify the ``keystroke is present'' determination in sgetc(), thus
making pccncheck() actually working without waiting for a keystroke.
for work regardless of whether there was an interrupt. This needs more
work, it should be able to run better when there are more than 3 host
cards present, ie: all cards in polling-only mode with no IRQ. (The
host cards have a choice of 3 irq's, 11, 12, or 15, or just polling)
little more reliably. So far I've received a couple of positive
responses and no objections to these changes.
There are two one-line changes:
- In wdprobe(), when testing the error status of drives, don't
unconditionally decide that there is no controller present if we
read back a value of 0x81 (drive 0 okay, drive 1 failed) twice
in a row. This may be caused by having an ATAPI CD-ROM jumpered
as a master on the controller with no slave.
- In wdgetctlr(), when checking for a status of WDCS_READY, check the
value twice. The first time may be bogus. This stops a phantom wd2
device from being detected when an ATAPI CD-ROM is attached to the
secondary controller alone as a slave. (This can cause installation to
fail when sysinstall attempts to open the phantom device and wedges the
system as a result. This has bitten me a couple of times on some
Gateway 2000 machines.)
. make pccncheck() work even when interrupts are disabled, so the
``Press a key on the console...'' procedure will work,
. make kernel colors #ifndef, so they can be overridden from the
config file,
. use shutdown_nice() instead of cpu_reset() if Ctrl-Alt-Del is
enabled,
. allow pccngetc() to return more than a single character, so the
arrow keys will work (and thus visual UserConfig!),
. fix a warning.
This closes all know PRs related to pcvt, in particular #845, #1236,
and #1265. PR #991 is a duplicate for 845, and PR #1283 has already
been fixed earlier in rev 1.11 of pcvt_conf.h.

This hack makes this 89.999928 Mhz clock correctly round to the closer

Changed i586_ctr_bias from long long to u_int. Only the low 32 bits
are used now that microtime uses a multiplication to do the scaling.
Previously the high 32 bits had to match those of rdtsc() to prevent
overflow traps and invalid timeval adjustments.
early enough when the dump device is specified in the config file.
Removed stale comment about configuration root and swap devices.
Don't bother clearing dumplo when dumpdev is set to NODEV. Everything
is controlled by dumpdev.
Fixed the kern.dumpdev sysctl. Writes were handle bogusly.
problem with the 'shell scripts' was found, but there was a 'strange'
problem found with a 486 laptop that we could not find. This commit
backs the code back to 25-jul, and will be re-entered after the snapshot
in smaller (more easily tested) chunks.
