ARCnet support
CONFIG_ARCNET
If you have a network card of this type, say Y and check out the
beautiful poetry in Documentation/networking/arcnet.txt in the
kernel source. If you get this driver to work or not, either way,
send mail to the author. You might also want to have a look at the
Ethernet-HOWTO, available via ftp (user: anonymous) in
sunsite.unc.edu:/pub/Linux/docs/HOWTO (even though arcnet is no true
ethernet). This driver is also available as a module ( = code which
can be inserted in and removed from the running kernel whenever you
want). If you want to compile it as a module, say M here and read
Documentation/modules.txt as well as
(arguably) beautiful poetry in Documentation/networking/arcnet.txt.

Enable arc0e (ARCnet "ether-encap" packet format)
CONFIG_ARCNET_ETH
This allows you to use "ethernet encapsulation" with your ARCnet card
via the virtual arc0e device. You only need arc0e if you want to
talk to nonstandard ARCnet software, specifically, DOS/Windows-style
"NDIS" drivers. You do not need to enable this option to communicate
with industry-standard RFC1201 implementations, like the arcether.com
packet driver or most DOS/Windows ODI drivers. RFC1201 is included
automatically as the arc0 device. Please read the ARCnet
documentation in Documentation/networking/arcnet.txt for more
information about using arc0e and arc0s.
Enable arc0s (ARCnet RFC1051 packet format)
CONFIG_ARCNET_1051
This allows you to use RFC1051 with your ARCnet card via the virtual
arc0s device. You only need arc0s if you want to talk to ARCnet
software complying with the "old" standard, specifically, the DOS
arcnet.com packet driver, Amigas running AmiTCP, and some variants of
NetBSD. You do not need to enable this option to communicate with
industry-standard RFC1201 implementations, like the arcether.com
packet driver or most DOS/Windows ODI drivers. RFC1201 is included
automatically as the arc0 device. Please read the ARCnet
documentation in Documentation/networking/arcnet.txt for more
