Test Descriptions

Prior to the execution of any of the EIDE tests, a validity check is

performed on the CLUN/DLUN pair specified by the EIDE “cf”

parameters. If either one of the values provided is invalid, the test aborts

and an error message is displayed.

General Configuration Description:

The EIDE diagnostics require some manual setup using the “cf” command

prior to execution. The default values are shown below:

Before running these tests, make sure that the CLUN/DLUN fields have

valid data as illustrated in Step 1 below. Additional parameters may be

changed as shown in Step 2 through Step 6.

1. EIDE CLUN and DLUN Fields.

The “EIDE CLUN and DLUN” fields are the most important fields in the

“cf” EIDE setup since they specify which drive is tested. The best way to

determine CLUN and DLUN field values for use in the “cf” setup is to run

the “ioi” command.

2. Test Sector Number Field.

The “Test Sector Number” field specifies a sector number to be used as a

starting location for several of the EIDE tests.
