ROM Memory Test
The ROM Memory Test is used to check the validity of the system
board code and fonts.
To run the ROM Memory Test:
1. Select ROM Memory Test from the menu. P and F represent
the same numbers for DRAM. The power indicator blinks
indicating the test is in process. The test runs continuously.
2. Press Return/Stop to exit the test.
Each time the test finishes, the screen updates with the result. If the
test passes, the Pass Count increases by 1, however if the test fails,
one of the following messages displays for approximately 3
seconds:
• ROM Checksum Error
• ROM Burst Read Error
Once the maximum pass count or fail count is reached, the test
stops with the power indicator on solid. The final results display on
the screen.
