Introduction

We have received reports that the AST 486 PREMIUM 486/33 may lose interrupts when used in NetWare v3.x server environments.

Refer to Cisco Technical Tips Conventions for more information on document conventions.

Q. How do I resolve lost interrupts with AST PREMIUM 486/33?

A. You receive a message similar to this (messages can vary with earlier NetWare releases):

Primary interrupt controller detected a lost hardware interrupt, or

Secondary interrupt controller detected a lost hardware interrupt

You can disable these messages with this SET command:
SET Display Lost Interrupt Alerts = OFF
The problem might not occur with all revisions of the motherboard and processor module. Novell has informed AST, and the problem is under investigation.

A similar problem was experienced when using an ALR VIESA 486/33. The workaround was to substitute an IDE.DSK driver for the standard ISA.DSK disk driver.
