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.

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

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.

Remove a redundant test in vm_uiomove (vm_map.c).

1. Determine whether the new range of pages actually overlaps

were to remove pages that were beyond the end of the object.)
2. Free any swap space allocated to removed pages.

v1.17 (1999/03/28) has xperimental fixes to 10Mbit autonegotiation and

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.

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

with malloc type at the tail of the list changed the list from

but it now causes weird output from `vmstat -m', probably because
a more important malloc type is now at the tail of the list.
Fix it by abusing ks_limit instead of ks_next as a flag for being
on the list. Don't forget to clear the flag when a malloc type is
uninit'ed. Uninit'ing is still fundamentally broken -- it loses
history.
udev_t in the kernel but still called dev_t in userland.
Provide functions to manipulate both types:
major() umajor()
minor() uminor()
makedev() umakedev()
dev2udev() udev2dev()
For now they're functions, they will become in-line functions
after one of the next two steps in this process.
Return major/minor/makedev to macro-hood for userland.
Register a name in cdevsw[] for the "filedescriptor" driver.
In the kernel the udev_t appears in places where we have the
major/minor number combination, (ie: a potential device: we
may not have the driver nor the device), like in inodes, vattr,
cdevsw registration and so on, whereas the dev_t appears where
we carry around a reference to a actual device.
In the future the cdevsw and the aliased-from vnode will be hung
directly from the dev_t, along with up to two softc pointers for
the device driver and a few houskeeping bits. This will essentially
replace the current "alias" check code (same buck, bigger bang).
A little stunt has been provided to try to catch places where the
wrong type is being used (dev_t vs udev_t), if you see something
not working, #undef DEVT_FASCIST in kern/kern_conf.c and see if
it makes a difference. If it does, please try to track it down
(many hands make light work) or at least try to reproduce it
as simply as possible, and describe how to do that.
Without DEVT_FASCIST I belive this patch is a no-op.
Stylistic/posixoid comments about the userland view of the <sys/*.h>
files welcome now, from userland they now contain the end result.
Next planned step: make all dev_t's refer to the same devsw[] which
means convert BLK's to CHR's at the perimeter of the vnodes and
other places where they enter the game (bootdev, mknod, sysctl).
Use colons instead of semi-colons in the default init_path to behave like
UNIX instead of DOS.

bad math: it does not handle page-boundary conditions, and will not
end up mapping all of the requested addresses. This will cause a panic:
page fault during probe on some systems. I have a machine that will
panic every time (when using the dpt driver) on kernel probe when there
are 5 drives installed. When there are 4 drives, it is fine.
Fix is to always allocate/deallocate an extra page.
