Jordan K. Hubbard 1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

THIS FILE IS SERIOUSLY OUT OF DATE AND NO LONGER REFLECTS
REALITY. THE ULTIMATE REFERENCE IS THE SOURCE CODE ITSELF.

----------------
The enclosed driver should be considered as beta-test software. It
has run on exactly one machine. Therefore testing has been limited.
This driver is in no way supported by Digital Equipment. See the
disclaimers in the sources for more.
This driver the DEC DE435 PCI NIC. It should also work with other PCI
boards that use the 21040-AA chip (also known as TULIP). This
driver requires the 21040-AA to be pass 2.3 or later. If you are
using a eariler pass chip, you may encounter undetected transmit
corruptions. This driver also requires that 21040-AA use a serial
Ethernet address ROM as described in the 21040 specification.
The DEC DE425 EISA NIC based on the 21040-AA is not support at
this time. A future update will include support for it.
The driver includes full support for both BPF and IP Multicast.
If the autosensing of the driver fails, you can use ifconfig(8) to
switch the driver to the correct port.
ifconfig de0 altphys Thinwire/AUI port
ifconfig de0 -altphys 10baseT/UTP port
To enable this driver, you first need to add the following lines to
your config file (in i386/conf):
controller pci0
device de0
The PCI support code will automatically determine and enable the
correct IRQ.
Now you are ready to rebuild your kernel, reboot, and see if the
driver can configure your board. When the system boots, you will
hopefully something close to:
de0 <digital 21040 ethernet> int a irq 9 on pci0:7
reg20: virtual=0xf290a000 physical=0xc0001000
de0: enabling Thinwire/AUI port
de0: 21040 [10Mb/s] pass 2.3 ethernet address 08:00:2b:e2:1e:09
bpf: de0 attached
in the startup log. If so, the board configured properly and
should be ready to use.
