+----------------
+
+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 DC21040-AA chip (also known as TULIP).  This
+driver requires the DC21040-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 DC21040-AA use a serial
+Ethernet address ROM as described in the DC21040 specification.
+
+The DEC DE425 ESIA NIC based on the DC21040-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
+
+This driver requires the NCR 53C810 PCI SCSI package to be installed.
+This can be obtained from FTP.Uni-Koeln.DE:~ftp/packages/FreeBSD.
+
+[All paths are relative to the top of sys source area, usually
+/usr/src/sys.]
+
+The following files need to be moved into their respective
+directories:
+
+	if_de.c	   	-->	i386/pci
+	dc21040.h	-->	i386/pci
+
+You will need to apply the following patches:
+
+	pat.files.i386  -->	i386/conf/files.i386
+	pat.pci		-->	i386/pci/pci.c, i386/pci/pci_config.c
+
+After that is done you will need to edit your config file (in
+i386/conf) and lines similar to:
+
+	controller pci0 at isa? irq 9
+	device de0
+
+The above assumes the board is configured to use IRQ 9 by your
+BIOS.  Change the IRQ if need to match your configuration.
+
+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:
+
+	on pci0:7 <digital dc21040 ethernet> irq a isa=9 [1] as de0
+	          memory size=0x1000 virtual=0xf25e9000 physical=0xc0001000
+	de0: enabling Thinwire/AUI port
+	de0: DC21040 pass 2.3 (TULIP) 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.
