           TITLE:  Access Server INT 4Bh Conflict
    DOCUMENT ID#:  TB.P.299
            DATE:  3 October 1991
         PRODUCT:  NetWare Access Server
PRODUCT REVISION:  v1.2
      SUPERSEDES:  N/A

         SYMPTOM:  Access Server Crash

ISSUE/PROBLEM

Novell Labs' testing of the Adaptec 1740 disk controller with the
NetWare Access Server v1.2 found an interrupt conflict (INT 4Bh)
between the Access Server and the Adaptec 1740 that caused the
Access Server to crash.  In particular, the conflict occurred when
the Access Server and Adaptec 1740 were configured for 1740
(Enhanced) mode.  No conflict existed when the selected
configuration was 1540 (Normal) mode.

SOLUTION

Novell engineering has changed the NetWare Access Server to correct
this conflict.  This patch (PTF274.ZIP) is available in the Network
Support Encyclopedia and on NetWire in downloadable library 9.
