Text file for the Linux SysKonnect Token Ring ISA/PCI Adapter Driver.
	Text file by: Jay Schulist <jschlst@samba.org>

The Linux SysKonnect Token Ring driver works with the SysKonnect TR4/16(+) ISA,
SysKonnect TR4/16(+) PCI, SysKonnect TR4/16 PCI, and older revisions of the
SK NET TR4/16 ISA card.

Latest information on this driver can be obtained on the Linux-SNA WWW site.
Please point your browser to: 
http://www.linux-sna.org

Many thanks to Christoph Goos for his excellent work on this driver and
SysKonnect for donating the adapters to Linux-SNA for the testing and 
maintenance of this device driver.

Important information to be noted:
1. Adapters can be slow to open (~20 secs) and close (~5 secs), please be 
   patient.
2. This driver works very well when autoprobing for adapters. Why even 
   think about those nasty io/int/dma settings of modprobe when the driver 
   will do it all for you!

This driver is rather simple to use. Select Y to Token Ring adapter support
in the kernel configuration. A choice for SysKonnect Token Ring adapters will
appear. This drives supports all SysKonnect ISA and PCI adapters. Choose this
option. I personally recommend compiling the driver as a module (M), but if you
you would like to compile it statically answer Y instead.

This driver supports multiple adapters without the need to load multiple copies
of the driver. You should be able to load up to 7 adapters without any kernel
modifications, if you are in need of more please contact the maintainer of this
driver.

Load the driver either by lilo/loadlin or as a module. When a module using the
following command will suffice for most:

# modprobe sktr

This will produce output similar to the following: (Output is user specific)

sktr.c: v1.01 08/29/97 by Christoph Goos
tr0: SK NET TR 4/16 PCI found at 0x6100, using IRQ 17.
tr1: SK NET TR 4/16 PCI found at 0x6200, using IRQ 16.
tr2: SK NET TR 4/16 ISA found at 0xa20, using IRQ 10 and DMA 5.

Now just setup the device via ifconfig and set and routes you may have. After
this you are ready to start sending some tokens.

Errata:
For anyone wondering where to pick up the SysKonnect adapters please browse
to http://www.syskonnect.com
