Bootrom Diagnostics
Bootrom Memory Test
While the Bootrom Memory Test is active, the status LEDs on the CPU
board indicate which phase of the test is running. The power-on LED is
actually bit 0 of the CPU LEDs. For the information in Table B-1, the Power-
on LED is ignored, making Bit 1 the lowest (bit 0), bit 2 is 1, and so on.
