PCI shared interrupts
Shared interrupts are normal in PCI servers, but not all PCI device drivers support them. Although these
adapters support shared interrupts, other PCI drivers used by your server may not.
If you are having problems with a shared interrupt, try one of the following:
• Use the BIOS setup program for your server to change the interrupt assigned to this adapter.
• Be sure that the adapter device driver loads AFTER the driver or any other device sharing this
interrupt.
• Contact the manufacturer of the other adapter or add-in card that is sharing this interrupt for a new
driver.
HP NC-Series Intel adapter diagnostics
Overview
The diagnostic software lets you test adapters to see if there are any problems with the adapter hardware,
cabling, or network connections. HP recommends that you run diagnostics every time you install an
adapter.
Prerequisites
The diagnostic utility runs under MS-DOS® v6.22 or later. It will not run from a DOS window in IBM
OS/2® or any Microsoft Windows products. This utility is designed to test hardware operation and
confirm the adapter's ability to communicate with another adapter in the same network, which primarily
confirms cabling status.
This diagostic utility is not a throughput measurement tool. The utility can test the adapter whether or not
there is a responder on the network; however, to conduct a thorough test you should set up a second
system on the network as a responder prior to starting a test.
Starting the DIAGS.exe tests
NOTE: If there is a DOS network driver present, such as NDIS2 or DOS-ODI, the test utility
and/or the network driver could become unstable. You should reboot and ensure that there are
no network drivers loaded.
