+----------------
+
+This driver is in no way supported by Digital Equipment.  See the
+disclaimers in the sources for more.
+
+This driver supports all the DEC EtherWORKS III NICs (DE203, DE204,
+and DE205) and the later DEC EtherWORKS II NICs (DE200, DE201, DE202,
+DE422).  DEPCA-style boards prior to the DE200 have not been tested
+and may not work.  
+
+This driver is not ESIA aware.  If you are using a DE422 or have
+configured the EtherWORKS III in EISA mode, make sure you specify
+the I/O port properly as this driver will *not* probe for it.
+(The I/O port should be 0xNc00 where N is the EISA slot number).
+
+This driver does not yet use the full 128KB allowed by the DE422.
+Someday, it might. For EtherWORKS III NICs, the driver will override
+the EEPROM setting of MemoryMode and *always* use the 2K for best
+results.
+
+The driver includes full support for both BPF and IP Multicast.
+
+[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_le.c	   -->	i386/isa
+	am7990.h   -->	i386/isa/ic
+	lemac.h	   -->	i386/isa/ic
+
+You will need to apply the patch provided in pat.files.i386 to
+i386/conf/files.i386 file.
+
+After that is done you will need to edit your config file (in
+i386/conf) and a line similar to:
+
+device le0 at isa? port 0x300 net irq 5 iomem 0xd0000 vector le_intr
+
+[The above line assumes the board is still at the factory defaults.]
+Change the port, irq, and iomem value if needed to 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:
+
+    EtherWORKS II:
+
+	le0 at 0x300-0x30f irq 5 maddr 0xd0000 msize 65536 on isa
+	le0: DE202 ethernet address 08:00:2b:2d:c8:45
+	bpf: le0 attached
+
+    EtherWORKS III:
+
+	le0 at 0x320-0x33f irq 5 maddr 0xd0000 msize 2048 on isa
+	le0: DE205-AB ethernet address 08:00:2b:bb:23:e0
+	le0 attached
+
+in the startup log.  If so, the board configured properly and
+should be ready to use.
