Hi. We are using Adaptec's AIC-7770 chipset on our pentium system under
ODT 3.0. Does this chipset support scatter/gather operations? If so, how
to configure it to enable this feature?
About half an year ago I was forced to disable scatter/gather in the
/etc/conf/pack.d/Sdsk/space.c file, since the system crashed repeatedly,
probably because AIC-7770 didn't not operate scatter/gather.
Since then it have worked fine. But about 200 users work on our system
and I want to speed up disks if possible.
There are notes in efs140btldoc that tell that at least AIC-7870 can be
configured to use scatter/gather by editing /etc/conf/pack.d/alad/space.c.
Probably the same can be achieved by editing /etc/conf/pack.d/arad/space.c,
but there are no comments concerning scatter/gather in neither
/etc/conf/pack.d/alad/space.c nor /etc/conf/pack.d/arad/space.c.
What have to be changed?
I'll appreciate any help.
