10 Technical Information PCI Installation Tips PCI computers are designed to automatically configure add-in cards each time the server starts. Your PCI server sets the I/O address and IRQ level for your network adapter when the server starts. The adapter software cannot change these values. If you experience a problem when the server starts, you may need to follow additional configuration steps. On some servers, manual configuration is possible through the server's PCI BIOS setup utility. Refer to your server's documentation. You may need to verify or change some BIOS settings. Some common PCI solutions are listed here: 1. Bus master-enabled slots. On some servers, not all slots are bus master enabled by default. Check your BIOS PCI bus setting. It will be set to either Busmaster or Non-busmastered. Choose Busmaster. 2. Reserve interrupts (IRQs) and/or memory addresses for ISA adapters. This prevents PCI cards from trying to use the same settings ISA cards are using. Check your PCI BIOS setup program. There may be IRQ options such as Enable for ISA, Reserve for ISA, or Disable for PCI. This option is sometimes in the Plug and Play area of the BIOS setup. 3. Enable the PCI slot. In some PCI servers, you must use the PCI BIOS setup program to enable the PCI slot. This is especially common in PCI servers with the PhoenixBIOS. 4. Update your PCI BIOS. An updated PCI system BIOS can correct some PCI configuration problems. Call your server manufacturer to see if an updated BIOS version is available for your server. 5. Configure the slot for level-triggered interrupts. The slot the adapter is using must be configured for level-triggered interrupts rather than edge-triggered interrupts. Check 41
