This file contain the old documentation of the Wavelan
driver. This is kept here for historical reason. Look the wavelan man
page or in wavelan.p.h for a more up to date documentation...

1. At present the driver autoprobes for a WaveLAN card only at I/O address 0x390.
The version of the card that I use (NCR) supports four I/O addresses (selectable
via a pair of DIP switches). If you want the driver to autoprobe a different
subset of the four valid addresses then you will need to edit
.../drivers/net/wavelan.c (near line 714) and change the initialisation of the
`iobase[]' array. Normally, I use a LILO configuration file directive to
obviate the need for autoprobing entirely, a course of action I heartily
recommend.
2. By default, the driver uses the Network ID (NWID) stored in the card's Parameter
Storage Area (PSA). However, the PSA NWID can be overridden by a value passed
explicitly as the third numeric argument to LILO's "ether=" directive, either
at the LILO prompt at boot time or within LILO's configuration file.
For example, the following line from such a LILO configuration file would
auto-configure the IRQ value, set the I/O base to 0x390 and set the NWID to
0x4321, all on a WaveLAN card labelled "eth0":
..
append ="ether=0,0x390,0x4321,eth0"
..
3. The driver uses the IRQ stored in the card's PSA.
To change this you will need to use the configuration/setup software that
accompanies each WaveLAN device. Yes, the driver should use the value passed
in via LILO and it will, just as soon as I can work out why that part of the
code doesn't work :-(.
4. If you encounter any problems send me some email.
Good luck,
