4.Set the test parameters:

a.Select YES for the CPU Speed Comparison, and press Enter.

b.Select Expected CPU Speed, and press Enter.

c.Select Run Test parameters, and press Enter.

To make sure the system configuration is not damaged, complete the following steps:

1.From the AMIDiag main menu, select System, and press Enter.

2.Select Processor Tests, and press Enter.

3.Select CMOS Validity Test, and press Enter.

To make sure that the PCI adapter slots are functioning correctly, complete the following steps:

1.From the AMIDiag main menu, select System, and press Enter.

2.Select Processor Tests, and press Enter.

3.Select PCI Test, and press Enter.

System Board Test

Select this choice to run a DMA controller test or a CMOS validity test.

DMA controller test: This test is a series of read and write tests on the memory address registers and page registers of direct memory address (DMA) controllers 1 and 2. The DMA controller manages the flow of information directly to and from system memory and an intelligentperipheral device, without passing through the microprocessor. On error, the AMIDiag program displays the register number, data written, and data read. To perform this test, complete the following steps:

1.From the main menu, select System, and press Enter.

2.Select DMA Controller Test, and press Enter.

CMOS Validity Test: Use this test to check the validity of the data in CMOS RAM, to make sure that the CMOS RAM checksums are correct, and to make sure that the battery is in good condition. To perform this test, complete the following steps:

1.From the main menu, select System, and press Enter.

2.Select CMOS Validity Test, and press Enter.

PCI System Test

Use the PCI System Test to make sure that the PCI bus and all PCI devices in the server are working properly.

Multiprocessor Test

Select this test when running the AMIDiag program in a server that has more than one microprocessor. This test performs a variety of diagnostic tests on all microprocessors. To perform this test, select Multiprocessor Test from the System menu, and press Enter. Follow the directions on the screen.
