Western Digital Cards on MCA machines
Western Digital have produced a number of different types of card which
are currently causing confusion. The SCO Unix TCP/IP networking software due for release
in January fails to function with the X3 (Surface Mount) revision of the card. The X4 and
X5 revisions of the card work correctly.
The X3 card can be made to function correctly through a kernel patch
which can be supplied from Unix Support.
All Western Digital cards run on the following settings under Unix.
|
Base Address |
280H |
|
Interrupt |
3 |
|
BIOS ROM Space |
Disabled |
|
Shared RAM |
C4000H |
The use of interrupt 3 which is normally allocated to the serial ports
means that the following commands must be run before the network software.
|
cd /etc/conf/cf.d |
|
./configure -c -d -m 5 -v 3 |
This command frees interrupt 3 for use by the Western Digital card.
