The vidcontrol command now accepts the following video mode names:
VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600
The VESA_800x600 mode is a raster display mode. The 80x25 text will
be displayed on the 800x600 screen. Useful for some laptop computers.
vidcontrol accepts the new `-i <info>' option, where <info> must be
either `adapter' or `mode'. When the `-i adapter' option is given,
vidcontrol will print basic information (not much) on the video
adapter. When the `-i mode' option is specified, vidcontrol will
list video modes which are actually supported by the video adapter.

HARP | Host ATM Research Platform
===================================
HARP 3
What is this stuff?
-------------------
The Advanced Networking Group (ANG) at the Minnesota Supercomputer Center,
Inc. (MSCI), as part of its work on the MAGIC Gigabit Testbed, developed
the Host ATM Research Platform (HARP) software, which allows IP hosts to
communicate over ATM networks using standard protocols. It is intended to
be a high-quality platform for IP/ATM research.
HARP provides a way for IP hosts to connect to ATM networks. It supports
standard methods of communication using IP over ATM. A host's standard IP
software sends and receives datagrams via a HARP ATM interface. HARP provides
functionality similar to (and typically replaces) vendor-provided ATM device
driver software.
HARP includes full source code, making it possible for researchers to
experiment with different approaches to running IP over ATM. HARP is
self-contained; it requires no other licenses or commercial software packages.
HARP implements support for the IETF Classical IP model for using IP over ATM
networks, including:
o IETF ATMARP address resolution client
o IETF ATMARP address resolution server
o IETF SCSP/ATMARP server
o UNI 3.1 and 3.0 signalling protocols
o Fore Systems's SPANS signalling protocol
What's supported
----------------
The following are supported by HARP 3:
o ATM Host Interfaces
- FORE Systems, Inc. SBA-200 and SBA-200E ATM SBus Adapters
- FORE Systems, Inc. PCA-200E ATM PCI Adapters
- Efficient Networks, Inc. ENI-155p ATM PCI Adapters
o ATM Signalling Protocols
- The ATM Forum UNI 3.1 signalling protocol
- The ATM Forum UNI 3.0 signalling protocol
- The ATM Forum ILMI address registration
- FORE Systems's proprietary SPANS signalling protocol
- Permanent Virtual Channels (PVCs)
o IETF "Classical IP and ARP over ATM" model
- RFC 1483, "Multiprotocol Encapsulation over ATM Adaptation Layer 5"
- RFC 1577, "Classical IP and ARP over ATM"
- RFC 1626, "Default IP MTU for use over ATM AAL5"
- RFC 1755, "ATM Signaling Support for IP over ATM"
- RFC 2225, "Classical IP and ARP over ATM"
- RFC 2334, "Server Cache Synchronization Protocol (SCSP)"
- Internet Draft draft-ietf-ion-scsp-atmarp-00.txt,
"A Distributed ATMARP Service Using SCSP"
o ATM Sockets interface
- The file atm-sockets.txt contains further information
What's not supported
--------------------
The following major features of the above list are not currently supported:
o UNI point-to-multipoint support
o Driver support for Traffic Control/Quality of Service
o SPANS multicast and MPP support
o SPANS signalling using Efficient adapters
This software was developed under the sponsorship of the Defense Advanced
Research Projects Agency (DARPA).

were to be rebooted after installing the 3.0 binaries without the
new kernel, the system is hosed.
The addition of this config file reserves the name of the config file
that the upgrade procedure uses. If an upgrade is to be performed on
a 2.2.5/6/7 system system for which a GENERIC kernel is inadequate,
this config file must be replace with a suitable one before performing
the upgrade.
On systems which report 'uname -r' as 3.0-CURRENT, the kernel build
is not performed and this file is ignored.

(Also added an MLINKS entry for the ThunderLAN man page which I forgot

- ppbus now supports PLIP via the if_plip driver
- ieee1284 infrastructure added, including parallel-port PnP
- port microsequencer added, for scripting the sort of port I/O
that is common with parallel devices without endless calls up and down
through the driver structure.
- improved bus ownership behaviour among the ppbus-using drivers.
- improved I/O chipset feature detection
The vpo driver is now implemented using the microsequencer, leading to
some performance improvements as well as providing an extensive example
of its use.

_KPOSIX_PRIORITY_SCHEDULING options to work. Changes:
Change all "posix4" to "p1003_1b". Misnamed files are left
as "posix4" until I'm told if I can simply delete them and add
new ones;
Add _POSIX_PRIORITY_SCHEDULING system calls for FreeBSD and Linux;
Add man pages for _POSIX_PRIORITY_SCHEDULING system calls;
Add options to LINT;
Minor fixes to P1003_1B code during testing.
Highlights:
* Simple model for underlying hardware.
* Hardware basis for timekeeping can be changed on the fly.
* Only one hardware clock responsible for TOD keeping.
* Provides a real nanotime() function.
* Time granularity: .232E-18 seconds.
* Frequency granularity: .238E-12 s/s
* Frequency adjustment is continuous in time.
* Less overhead for frequency adjustment.
* Improves xntpd performance.

Uncommented css0. It compiles OK.
Moved trix0 so that it compiles OK when uncommented. Uncommented
it. Drivers with the same interrupt handler must be together in
config files so that config(8)'s simple avoidance of redundant
declarations of interrupt handlers works (config emits a declaration
unless it would duplicate the previous one).
Commented out NO_LKM. Negative options should not be configured
in LINT. There should be no negative options for subsystems.
LKMs should never have been standard or the default.
If you want to play with it, you can find the final version of the
code in the repository the tag LFS_RETIREMENT.
If somebody makes LFS work again, adding it back is certainly
desireable, but as it is now nobody seems to care much about it,
and it has suffered considerable bitrot since its somewhat haphazard
integration.

This introduce an xxxFS_BOOT for each of the rootable filesystems.
(Presently not required, but encouraged to allow a smooth move of option *FS

LFS is temporarily disabled, and will be re-enabled tomorrow.
This is Junichi's v1.0 driver.

playing with it. Please submit bugs to junichi and myself.

original BSD code. The association between the vnode and the vm_object
no longer includes reference counts. The major difference is that
vm_object's are no longer freed gratuitiously from the vnode, and so
once an object is created for the vnode, it will last as long as the
vnode does.
When a vnode object reference count is incremented, then the underlying
vnode reference count is incremented also. The two "objects" are now
more intimately related, and so the interactions are now much less
complex.
When vnodes are now normally placed onto the free queue with an object still
attached. The rundown of the object happens at vnode rundown time, and
happens with exactly the same filesystem semantics of the original VFS
code. There is absolutely no need for vnode_pager_uncache and other
travesties like that anymore.
A side-effect of these changes is that SMP locking should be much simpler,
the I/O copyin/copyout optimizations work, NFS should be more ponderable,
and further work on layered filesystems should be less frustrating, because
of the totally coherent management of the vnode objects and vnodes.
Please be careful with your system while running this code, but I would
greatly appreciate feedback as soon a reasonably possible.

XXX this uses some rather ugly PnP bootstrap code that is *NOT* compatable
with 'controller pnp0' or *ANY* other PnP devices. If you use some other
PnP devices, enabling css0 will burn your house down. :-] The
"simplified" PnP init sequence directly blats your config(8) settings onto
the chip. I'm pretty sure 'css0' will conflict with 'mss0', this whole
area desperately needs a cleanup.
I have been using the following with some success on the PR440FX:

device css0 at isa? port 0x534 irq 5 drq 1 flags 0x08 vector adintr
device opl0 at isa? port 0x388

Here are the remanding changes required to support the Ensoniq
Soundscape using FreeBSD 3.0-current.
Notes:
1) ad1848_init already has code to detect if DMA_DUPLEX should
be set so it is not necessary (and is in fact a mistake) to
hard code setting it. Not all soundcards (i.e. the current
sscape driver) are capable of using DMA_DUPLEX.
2) The other changes are hopefully self explanatory. Feel free
to let me know if you need additional information.

you don't want this (and the documentation explains why), but if you
use ipfw as an as-needed casual filter as needed which normally runs as
'allow all' then having the kernel and /sbin/ipfw get out of sync is a
