|
A fmvj18x (and its compatibles) PCMCIA client driver
|

TDK LAK-CD021 and CONTEC C-NET(PC)C support added by

|
|
The PCMCIA client code is based on code written by David Hinds.
|
Network code is based on the "FMV-18x driver" by Yutaka TAMIYA
|
but is actually largely Donald Becker's AT1700 driver, which

carries the following attribution:
