SCO Xenix 2.3.4 & XEN-LS II with Adaptec
154* SCSI Cards
To configure Adaptec 154* SCSI cards on SCO Xenix 2.3.4 the following
must be done:-
- Alter the hardware interrupt via the jumpers on the card on bank J9 (for
B revision cards) to be interrupt 9.
- We recommend disabling the Audio from the XEN-LS II setup as this will
allow DMA channels 1 or 3 to also be used. The Adaptec default of channel 5 should however
work.
- Change the software interrupt of the card from 11 to 9. Under Xenix
change the following line in /usr/sys/conf/master
ad0 1 0337 014 ad0 0 34 34 1 5 33 0 0 0
to
ad0 1 0337 014 ad0 0 34 34 1 5 31 0 0 0
- Rebuild the kernel by running the following command in the directory
/usr/sys/conf
|
./configure -r |
|
./link_xenix |
|
./hdinstall |
- Now reboot the machine and the card should be seen correctly.
