287911bd50 Go back to separate tests for configuration mechanism 1 and mechanism 2.
Require the state of the configuration enable bits to be OFF assuming
that the BIOS left them that way, as it should anyway to avoid bad things
to happen.

The tests themselves are copied from the previous release, with the
exception of CONF1_ENABLE_MSK1 having the LSB set. This bit should be
read back as '0', since only DWORD addresses are legal.

9b3e7ec49d Latest fixes from Serge:
I tried to solve the problem of IDE probing compatibility in this version.
When compiled without an ATAPI option, the wd driver is
fully backward compatible with 2.0.5.  With ATAPI option,
the wdprobe becomes strictly weaker.  That is, if wdprobe works
without ATAPI option, it will always work with it too.

Another problem was with the CD-ROM drive attached as a slave
in the IDE bus, where there is no master.  All IDE CD-ROM
drives are shipped in slave configuration, and most users
just plug them in, never thinking about jumpers.
It works fine with ms-dos and ms-windows, and this
version of the driver supports it as well.

The eject op can now load disks.  Just repeat it twice,
and the disk will be ejected and then loaded back.

The disc cannot be ejected if it is mounted.

e2d4b1f051 Reduce jitter of Pentium microtime() implementation by letting the counter
free-run and doing a subtract in microtime() rather than resetting the
counter to zero at every clock tick.  In combination with the changes to
kern_clock.c, this should eliminate all the immediately obvious sources
of systematic jitter in timekeeping on Pentium machines.

edeea08413 1) Fixed irq logic so that it uses the kernel configured irq if it doesn't
match the board setting.
2) Fixed the warning message to properly print the irq mismatch (as opposed
   to the bit encoded value).
3) Add irq autodetection if the kernel has "?" or no irq specified.
4) Add missing splimp protection in ixioctl().

0134f4737b o Support for CDIOCPREVENT and CDIOCALLOW ioctls that xcdplayer
were making and were no-brainers.  However, the xcdplayer
    eject button didn't work because xcdplayer gave up and didn't bother
    to try the EJECT ioctl anyway when CDIOCALLOW was not available.
    This all works now.

o   A change so that xcdplayer gets TOC entry data for the lead-out area
    on the disc.  Xcdplayer can now play the last track on a CD, which
    it would not do in earlier versions (but no one reported).
    Cdplayer gets the TOC data differently and it works in old and new
    versions.

o   Eliminated a race condition that caused the driver to sleep forever
    on very slow and heavily loaded systems on rare occasions when
    the system was doing lots of audio-related ioctls to the drive.

o   Fixed a problem where a locked drive could be unlocked by accessing
    one of the non-locking devs.  Door locking now follows the documented
    rules.

o   Made all wait channel strings unique to matcd.

2b76bec4e6 if_ze.c was derived from if_ed.c about 42 (!) versions ago. It is now
scheduled for demolition.  This is a first step: get rid of if_zereg.h,
by adding the five extra definitions to if_edreg.h.
Also add some definitions which will become needed when if_ze.c gets
replaced entirely by pccard and if_ed.c.  (this is a 2.1.0 candidate)

832e06d4dc From Bruce Evans: (prototype related changes, other cleanups)
Add prototypes.  Use static for function definitions to match existing
prototypes.  Otherwise leave functions that should be static as extern.
TODO: declare everthing except sidriver and siintr as static.  I use
some new cdevs registration functions to do this for syscons and pcvt.

Fix siintr() to match its prototype in ioconf.c (don't return anything).
This may break the eisa support, but Julian says that eisa interrupts
never worked anyway.

(EISA support was never tested anyway - Peter)

e7451974bb Make pcvt and syscons live in the same kernel. If both are enabled, then
the first one in the config has priority.  They can be switched using
userconfig().

i386/i386/conf.c:
Initialize the shared syscons/pcvt cdevsw entry to `nx'.

Add cdevsw registration functions.

Use devsw functions of the correct type if they exist.

i386/i386/cons.c:
Add renamed syscons entry points to constab.

i386/i386/cons.h:
Declare the renamed syscons entry points.

i386/i386/machdep.c:
Repeat console initialization after userconfig() in case the current
console has become wrong.  This depends on cn functions not wiring down
anything important.

sys/conf.h:
Declare new functions.

i386/isa/isa.[ch]:
Add a function to decide which display driver has priority.  Should be
done better.

i386/isa/syscons.c:
Rename pccn* -> sccn*.

Initialize CRTC start address in case the previous driver has moved it.

i386/isa/syscons.c, i386/isa/pcvt/*
Initialize the bogusly shared variable Crtat dynamically in case the
stored value was changed by the previous driver.

Initialize cdevsw table from a template.

Don't grab the console if another display driver has priority.

i386/isa/syscons.h, i386/isa/pcvt/pcvt_hdr.h:
Don't externally declare now-static cdevsw functions.

i386/isa/pcvt/pcvt_hdr.h:
Set the sensitive hardware flag so that pcvt doesn't always have lower
priority than syscons.  This also fixes the "stupid" detection of the
display after filling the display with text.

i386/isa/pcvt/pcvt_out.c:
Don't be confused the off-screen cursor offset 0xffff set by syscons.

kern/subr_xxx.c:
Add enough nxio/nodev/null devsw functions of the correct type for syscons
and pcvt.

2bf07b2bd7 Patch to the atapi driver, by Serge V.Vakulenko, minor changes
by me...

Original message:

This patch upgrades the ATAPI CD-ROM driver to version 1.3.

It has three bugs fixed:

1) The `controller not ready' message at startup and later.
   It was caused by staled media change bit.

2) Incorrect shuffling of model string for some drives (NEC, Mitsumi).

3) Handling of drives which report itself as been of direct-access type,
   instead of CD-ROM type.

There is one known bug which is not fixed yet -- probing
in absense of IDE disks. A work-around exists though (thanks Steve!).
If you have no IDE disks attached, then remove them from the kernel
config file to make the CD-ROM attach correctly.
Unfortunately, there is no way to disable them from the kernel
interactive config mode.
