PCI Data Parity NMI enables the generation of a non-maskable interrupt when a PCI data parity error occurs. CPU-PCI Write Buffers enables the CPU to PCI write posting. SCSI ROM Address lets you specify the I/O address of the server′s imbedded SCSI controller. The PCI Master Latency Timer values can be set for both the primary and secondary buses.

2.1.2 BIOS Updates

The BIOS of PCI/EISA servers are located in a flash ROM on the motherboard. If necessary, it can be updated with a new version that can be obtained from the Web.

For more information on how to obtain BIOS updates, please refer to

Appendix A, ªSources of Drivers and Informationº on page147.

2.2 EISA Configuration Utility

This utility is used when you add or remove an ISA or EISA adapter. We use an example to illustrate the process. In our example, we add an Auto Token-Ring 16/4 ISA adapter in slot 3 of a PC Server 320. The steps to complete the process are as follows:

1.Boot with the EISA configuration utility diskette.

2.Answer Y to the following question:

Do you want to configure your system now [Y,N]?

3.The welcome panel will appear. Press Enter to continue. A panel similar to the one in Figure 3 on page 10 will then appear.
