+ and read the Ethernet-HOWTO, available from
+ <http://www.tldp.org/docs.html#howto>.
+
+ Note that the answer to this question doesn't directly affect the

+ ---help---
+ Say Y here if you intend to attach a Fujitsu FMV-J18x or compatible
+ PCMCIA (PC-card) Ethernet card to your computer.
+
+ To compile this driver as a module, choose M here: the module will be
+ called fmvj18x_cs. If unsure, say N.

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