keyboard and video card drivers.
Because of the changes, you are required to update your kernel
configuration file now!
The files in sys/dev/syscons are still i386-specific (but less so than
before), and won't compile for alpha and PC98 yet.
syscons still directly accesses the video card registers here and
there; this will be rectified in the later stages.
+ ECP parallel port chipset FIFO detection
+ DMA+FIFO parallel I/O handled as chipset specific
+ nlpt updated in order to use the above enhanced parallel I/O.
Use 'lptcontrol -e' to use enhanced I/O
+ Various options documented in LINT
+ Full IEEE1284 NIBBLE and BYTE modes support. See ppbus(4) for
an overview of the IEEE1284 standard
+ Detection of PnP parallel devices at boot
+ Read capability added to nlpt driver to get IEEE1284 compliant
printer status with a simple 'cat /dev/lpt0'
+ IEEE1284 peripheral emulation added to BYTE mode. Two computers
may dialog according to IEEE1284 signaling method.
See PERIPH_1284 option and /sys/dev/ppbus/ppi.c
All this code is supposed to provide basic functions for IEEE1284 programming.
ppi.c and nlpt.c may act as examples.

here (for translate_bytes()) is now an interesting example of one
that needs to be volatile to work.
Fixed missing "memory" in the clobber list for translate_bytes().
Submitted by: "John S. Dyson" <dyson@iquest.net> but rewritten by me
from sc, vt and sio drivers. Use instead a linker_set to collect them.
Staticize ??cngetc(), ??cnputc(), etc functions in sc and vt drivers.
We must still have siocngetc() and siocnputc() as globals because they
are directly referred to by i386-gdbstub.c :-(

few days while this has been sitting ready to go.
(Part 1 was committed to the config files, but cvs aborted grrr..)

in cyopen() were done in a different order than in sioopen(), partly
to (ab)use a side effect of comparam() and partly because I didn't
understand what the reset was doing (it flushes the fifos). This
turned out to be more than a cosmetic problem. Flushing the fifos
quite late is good for discarding input that arrived while the line
state was being initialized, and in the cy driver it also seems to
reduce a problem with input that arrived long ago during the previous
close (the UART loses sync too easily and for too long).
change the original code but add an extra option "ALI_V" to check the
precise IDE port.(especially, secondary) Use the same option "ALI_V" on
the kernel config file to prevent generic DMA check causes wrong result.
(It seems buggy even on PIIX4 chipset, and I don't know when this bug start)
Should I add the option "ALI_V" into /sys/i386/conf/LINT ?
