Warning Prompt screen capture reads: "Warning: This test utility, as part of its normal test processes, will automatically clear the System Event Log (SEL) upon exiting. We strongly urge you to save the SEL to a floppy diskette using the SSU Utility prior to running this test to maintain a permanent record of the SEL. The PCT, when run in continuous loop mode, is sensitive as to when the test is manually interrupted using the ctrl-break key combination. We recommend that the tests not be interrupted during the Hardware Probe or during the PMC test module. Aborting during the Hardware Probe or the BMC test can cause unpredictable results. Press ENTER to continue or ESC to exit."
