motherboard will have a card for the "motherboard" on slot 0.
eisa0: <EISA bus> on motherboard
mainboard0: <ASU5101 (System Board)> at slot 0 on eisa0
This should stop the probe "detecting" an EISA bus everywhere that has
a 'controller eisa0' line regardless of whether it's really there.
A very nice i/o board with 16 open collector outputs (capable of driving 5-40v)
and 16 inputs
Also has 2 16 bit cascadable counters (10Mhz clock) capable of
generating interrupts.
It is a PCI card, and emulates the Intel 8254 timer.
It uses the PLX PCI-9050 PCI bus interface to map the
8254 style hardware and the i/o registers into the IO space.

Change Intel GPIO mask to hopefully stop turning the Intel Camera off
Fixed tuner selection on Hauppauge card with tuner 0x0a
Replaced none tuner with no tuner for Theo de Raadt <deraadt@openbsd.org>.
Ivan Brawley <brawley@internode.com.au> added
the Australian channel frequencies.
Clean up the handling of failure modes in our attach so we don't free
resources twice. ahc_free() will do all of the work for us (as would
be required by an unload event) so we only need to handle resources that
the softc has not taken ownership of.
Fixed problems:
LS120 drives currupted data.
The workaround for drives not supporting upto 64K transfers
has been reworked. It works now both on LS120 & ZIP drives.
ISA only configs wont compile.
Fixed.
The ATA driver wont share interrupts.
Fixed.
The "unwanted interrupt" warning gave wrong controller.
Another lun<>unit messup from the newbus integration.
Some minor cleanups and rearrangements as well.
As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code.
Especially the DMA support can hose your disk real bad if anything
goes wrong, again you have been warned :)
Notebook owners should be carefull that their machines dont suspend
as this might cause trouble...
But please tell me how it works for you!
Enjoy!

Change reference count in struct ifaddr to a u_int, to be able
to handle more than 2^16 routes to the same interface.
Fix suggested by Andrew Bangs <andrewb@demon.net> in PR kern/10570.
Tested by <adrian@freebsd.org> and me under -current.
Remove a useless argument from vm_map_madvise's interface (vm_map.c,
vm_map.h, and vm_mmap.c).
Remove a redundant test in vm_uiomove (vm_map.c).
Make two changes to vm_object_coalesce:
1. Determine whether the new range of pages actually overlaps
the existing object's range of pages before calling vm_object_page_remove.
(Prior to this change almost 90% of the calls to vm_object_page_remove
were to remove pages that were beyond the end of the object.)
2. Free any swap space allocated to removed pages.
though, on systems (386 mostly) that still have a seperate fpu, but it
might be possible to find systems where the FPU coprocessor is wired to
a different IRQ pin.
docs don't seem to shed light on why this is needed, but reports from
the field indicate this helps prevent problems in this area. Ken's
changes seem to have exposed this bug, rather than caused it, as far
as I can tell.
Thanks to Jack O'Neill for tracking this down.

Very strong 3.2 merge candidate.
It never makes sense to specify MAP_COPY_NEEDED without also specifying
MAP_COPY_ON_WRITE, and vice versa. Thus, MAP_COPY_ON_WRITE suffices.

instances to a parent bus.
* Define a new method BUS_ADD_CHILD which can be called from DEVICE_IDENTIFY
to add new instances.
* Add a generic implementation of DEVICE_PROBE which calls DEVICE_IDENTIFY
for each driver attached to the parent's devclass.
* Move the hint-based isa probe from the isa driver to a new isahint driver
which can be shared between i386 and alpha.
Sync up device Ids with the master Adaptec list.
Add probe support for the 2940 Pro although it isn't obvious that
all of the termination support is correct for this adapter yet.
tell the sequencer to pause itself for a target msg variable update. This
avoids the pause race entirely as HS_MAILBOX can be accessed without

v1.19 (1999/04/15) updates the CEM56/REM56 support.
Current bugs & misfeatures
--------------------------
* CE2 cards still not working reliably. Unclear if this is related to
packet I/O code or interrupt handling.
* Autonegotiation support remains flaky. We're now OK with 10Mbit auto
hubs, but certain combination of hardware will fail to connect.

v1.17 (1999/03/28) has xperimental fixes to 10Mbit autonegotiation and
CE2 input lockup.
KNOWN BUGS
==========
* Media auto-negotiation is definitely not right. It will work in most
circumstances and seems to connect OK to most 100Mbit networks, however some
pathological combinations of hubs/networks/peers seem to confuse it.
* CE2 support is somewhat flakey (ranging from 'works perfectly' to 'hangs the
machine' so far). I've fixed the probe routine and a potential lockup in
the output routine, but a lot of people still report that they can't receive
or transmit.
* You won't be able to use the modem and Ethenet parts of a multifunction card
simultaneously. This is limitation the current FreeBSD PCMCIA support.
Likewise, there is no support for CardBus devices.

making our life considerably easier -- thanks Werner!
This driver supports:
* Intel EtherExpress(TM) PRO/100 PCCARD (16-bit version)
* Xircom CreditCard CE2 / CEM28 / CEM33 / CE3 / CEM56 Ethernet adapters.
* Toshiba Advanced Network 10/100 PCCARD
* Certain Compaq Netelligent 10/100 branded cards

inodes were synced every 15 seconds. This is now reversed as during

likely to be written by the time that the directory is written thus
reducing the number of directory rollbacks that are needed.
