Reconfiguring the NIC 4-3
You can configure an ISA NIC for EISA mode only if it is 
in an EISA slot.
If you have configured an ISA NIC for an EISA PC, the 
PROTOCOL.INI file looks for the parameter SLOT=number 
rather than the I/O base address. The SLOT number is 
required only if you have multiple NICs installed.
The following procedures are general. Refer to the 
configuration documentation provided with your PC for 
more details.
Changing NIC Configuration from ISA to EISA
To configure the NIC for an EISA PC:

2 When the main menu appears, select Configuration 
and Diagnostic Program.
3 If necessary, use the arrow keys to select the NIC 
you want to configure. Tab to the Select button 
and press [Enter].
4 If you have multiple NICs installed, use the arrow 
keys to select a NIC and press [Enter].
5 A screen identifying the NIC appears with the Test 
menu bar item highlighted.

the Configure NIC option. Press [Enter].
