LXETH (The HP200LX Ethernet Packet Driver) is an open-source freeware packet driver for ethernet cards that are compatible with the HP200LX palmtop.
Currently, the Accton EN2216-1 ethernet card is fully supported. Other NE2000 compatible cards are reported to work with the same driver.
LXETH is available from SourceForge.
Please note that I no longer support LXETH.
If you would like to become the LXETH maintainer, then please contact me.
