[comp.unix.i386] Adaptec 2322B ESDI controller

neighorn@qiclab.UUCP (Steven C. Neighorn) (01/14/90)

Greetings,

   I am trying to find out whether or not the Read Ahead Cache on the 2322B
ESDI controller can be used with AT&T Unix V3.2?

   I have a 2322B/Maxtor 4380E hard drive combo. The 2322B is capable of
utilizing a read-ahead cache by removing J2-5 on my rev of the board. Does
anyone in netland have experience with this controller and 386 Unix?

   Any information will be greatly appreciated. Thanks...

The read ahead cache cannot be used with *ANY* version of UNIX/XENIX/Novell.
We are looking into what the problem may be, but do not have an answer yet.

As much as I hate to disagree with Roy, we have 2 systems running with
an ACB2322B, apparently with the read-ahead cache enabled, and both
are working perfectly well with both SCO Xenix 2.3.2 and SCO Unix V.

Roy, what do you think the problem is, are we living with a time bomb???

I am really curious about this, as the ACB2322B is the only ESDI controller
I have been using that has been relatively trouble free.

Really ?  I am running the Adaptec 2322B-8 hooked up to my
Miniscribe 9380E, and haven't had *any* problems since I
swapped out my unsupported DTC controller and put in the
Adaptec.  The read ahead cache is enabled.  If the Adaptec
*doesn't* work under UNIX with the read ahead cache enabled,
what sorts of problems/errors does it cause ?  BTW, I am 
running ISC 2.0.2 on a 33Mhz w/32k SRAM cache.
