----------------
|
|
|
|
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 EISA 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
|
|
|
|
[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.
