Move the relocated boot1 and arg transfer space from 0x600/0x800 to
0x700/0x900. In theory this should make no difference, apart from the fact
that Buslogic controllers happen to use a few bytes at 0x600 for some sort
of scratch space for it's int 0x13 hook (!!!), causing the machine to crash
badly when the boot2 code makes it's callbacks into boot1 for disk IO.

+ 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.
It was nay'ed before committing on the grounds that this is not
the way to do it, and has been decided as such several times in
the past.
There is not point in loading gobs of ascii into the kernel when
the only use of that ascii is presentation to the user.
Next thing we'd be adding all section 4 man pages to the loaded
kernel as well.
The argument about KLD's is bogus, klds can store a file in
/usr/share/doc/sysctl/dev/foo/thisvar.txt with a description and
sysctl or other facilities can pick it up there.
Proper documentation will take several K worth of text for many
sysctl variables, we don't want that in the kernel under any
circumstances.
I will welcome any well thought out attempt at improving the
situation wrt. sysctl documentation, but this wasn't it.

bzero to MEMZERO (portability with **nux). Use memcpy for same reason.
Finally detect QUEUE FULL conditions and return this as an error that

the answer.
If we later get a descriptor exception from select(), we know
that it's a tty (isatty() returns 0 after the exception on a
tty) and remember to call modem_LogicalClose().
The upshot of it all is that descriptor exceptions dont leave
the tty locked any more.
than ".so". The old extension conflicted with well-established
naming conventions for dynamically loadable modules.
The "clean" targets continue to remove ".so" files too, to deal with
old systems.

on the ASIX AX88140A chip. Update /sys/conf/files, RELNOTES.TXT,
/sys/i388/i386/userconfig.c, sysinstall/devices.c, GENERIC and LINT
accordingly.
For now, the only board that I know of that uses this chip is the
Alfa Inc. GFC2204. (Its predecessor, the GFC2202, was a DEC tulip card.)
Thanks again to Ulf for obtaining the board for me. If anyone runs
across another, please feel free to update the man page and/or the
release notes. (The same applies for the other drivers.)
FreeBSD should now have support for all of the DEC tulip workalike
chipsets currently on the market (Macronix, Lite-On, Winbond, ASIX).
And unless I'm mistaken, it should also have support for all PCI fast
ethernet chipsets in general (except maybe the SMC FEAST chip, which
nobody seems to ever use, including SMC). Now if only we could convince
3Com, Intel or whoever to cough up some documentation for gigabit
ethernet hardware.
Also updated RELNOTEX.TXT to mention that the SVEC PN102TX is supported
by the Macronix driver (assuming you actually have an SVEC PN102TX with
a Macronix chip on it; I tried to order a PN102TX once and got a box
labeled 'Hawking Technology PN102TX' that had a VIA Rhine board inside
it).
devices dynamically. That means,
+ only one /dev/iic or /dev/smb device for each smb/iic bus to access
+ I2C/SMB device address must be given to any ioctl
+ new devices may be plugged and accessed after boot, which was
impossible previously (device addresses were hardcoded into
the kernel)
getvfsent() in most cases. (The main exception is when /etc/fstab
still hasn't been converted to use a slice for the root device, the
root device is a SCSI device, and the /dev/sd* inode for this device
still hasn't been renamed to /dev/da*.)
