Abstract: LOST HARDWARE INTERRUPTS RUNNING NOVELL NETWARE 3.12
SYMPTOM:
The NetWare Server Console displays the message - "Secondary
Hardware Interrupt Controller detected a lost hardware
Interrupt"
Some examples include: when a Windows 95 Client try's to run
applications from the Server, or when a large file copy
occurs to or from the Server over the Network.
PROBLEM ISOLATION AIDS:
FIX:
Eliminate use of Interrupt 15 by Adapters/Controllers.
Depending on the Server, this may require allocating another
Secondary Interrupt to a slot that was previously set to
"automatic", or to a adapter / controller that was previously
set to Interrupt 15, or reserve Interrupt 15 so that no devices
will use it.
NOTE: At this time, Only the PC Server 300 assigns one Interrupt
to the entire PCI Bus. The latest Version BIOS for that
server defaults the PCI Bus assignment to Interrupt 15.
Refer to the users manual for the Server on information about
Interrupt settings / assignments.
Detail:
This error may appear due to a load applied to any adapter that
is using Interrupt 15.
NetWare uses IRQ15 (Interrupt 15) to process lost Interrupts.
In some situations, setting a Adapter / Controller to use IRQ15
will cause conflicts. For more information, see the NetWare
troubleshooting Tip# 21620 located at the NetWare Website.
