For example, even though EGA and
VGA video adapters are installedand
potentially can use IRQ 2, most ap-
plications do not; hence, IRQ 2 may be
available for use with the Ethernet
adapter Likewise, even though you
have a printer installed at LPTl, using
IRQ 7 may not create a problem. This
is because most applications do not
use LPTl with intermpts.
The Ethernet adapter has been
designed for maximum configuration
flexibility using a minimum number of
jumpers. This is achieved primarily
through the use of the Wl jumper
block.
Wl jumper block allows you to
choose among three options: two
preassigned hardware configuration
settings and one setting which .
enables you to select any valid con-
figuration via the software setup pro-
gram that comes with the adapter
The setup program provides a variety
of additional configuration settings
from which to choose.
Note: The factory-configured I/O
base address associated with the soft
jumper setting is 240, and both the
RAM base address and the IRQ set-
tings are disabled to avoid conflicts.
In addition to jumper block W l , there
is a W2 jumper block. W2 enables
you to select memory space for an op-
tional ROM device. See Figures 1,2,
and3 inthe Introduction. •
W l :
The W1 jumper block sets the .
adapter's I/O base address, IRQ level,
and on-board shared memory base ad-
dress (RAM). Table 4 shows the set-
tings associated with the three
possible jumper configurations.
If the factory default setting (I/O base
address 280, IRQ 3, RAM base ad-
dress D0000-D3FFF) conflicts with
the configuration of another board or
computer function, use the other
jumper setting (1/0 base address 300-
31F, IRQ 10, RAM base address .
