CrossBrand - Netware 3.12 lost hardware interrupt
Applicable to: World-Wide
Symptom :
NetWare 3.12 issues lost hardware interrupt errors (on the server console) when logging onto the Server or performing any network activity.
Problem Isolation Aids :
The system is a PC Server 310 (8639), a PC 300 (65xx), or a PC 700 (68xx) with BOTH an IBM Auto ISA 16/4 Token Ring Adapter FRU p/n 41H8452 (Option p/n 92G7632) and an Adaptec AHA-2940 PCI SCSI Adapter FRU p/n 06H5250 with BIOS 1.11, 1.16, or 1.19 installed.
Fix :
Ignore and disable the interrupt alerts by adding the following statement to the STARTNET.CFG file:
SET DISPLAY INTERRUPT ALERTS = OFF
-OR-
Install NetWare 4.x
-OR-
Install a PCI Token Ring Adapter.
This alert is actually a "spurious interrupt" warning message and does not cause any disruption in the network activity.
The alert is due to "extra level trigger to edge trigger conversion" pulse that the VLSI interrupt controller is generating. Normally, a PCI interrupt (two pulses internal to the VLSI Interrupt Controller Chip) is converted to an ISA interrupt. In this case, three(3) or more pulses are generated by the VLSI Controller after receiving an interrupt request from the Adaptec SCSI Adapter. This third pulse causes the "lost hardware interrupt " error message to appear.
