Title: Config.sys File Entries for EtherLink Cards

When the DMA, INT and base I/O addresses have been changed on an
EtherLink card, these changes need to be stored in the
config.sys file of the PC/Server or workstation that the card is
in.  Below are the correct config.sys file entries for various
types of EtherLink cards.


For the EtherLink 3C501 card with default settings (DMA=1, INT=3,
base I/O=300):

  device=eth.sys


For non-default 3C501 cards with a DMA of 3, an INT of 5, and a
base I/O of 320:

 device=eth.sys INT I/O DMA
 device=eth.sys 5 320 3


For the EtherLink Plus card 3C505 with default settings:

 device=eth505.sys INT I/O DMA
 device=eth505.sys


For the EtherLink Plus card 3C505 with a DMA of 5, INT of 10, and
a base I/O of 340:

 device=eth505.sys INT I/O DMA
 device=eth505.sys 10 340 5


If you are using the Link Plus Optimizer, enter the parameter
changes on the PSH.SYS line instead of the eth505.sys line.  For
example:

 device=psh.sys INT I/O DMA
 device=psh.sys 10 340 5


For the EtherLink II card 3C503 the only hardware-switchable
setting is the base I/O address for the card.  The DMA and INT are
set using the config.sys file only.  The config.sys file for
default settings would be:

 device=eth503.sys INT I/O DMA transceiver (internal)
 device=eth503.sys


For the EtherLink II card 3C503 with a DMA of 2, an INT of 5, a
base I/O of 340, and an external transceiver:

 device=eth503.sys INT I/O DMA tran
 device=eth503.sys /i:5 /a:310 /d:3 /t:2
