[SunRescue] Help with SS1000E

[Brian McCloskey]

the first two green led's are just to show if there are cpu's installed on 
the board. both off=no cpu's or no recognized cpu's. the amber led's you 
describe seem to signify that the tod and memory tests are being conducted. 
from the sparc hardware reference:


The eight LEDs are used for diagnostic purposes. In the chart
        below, a "1" indicates a lit LED, and a "0" indicates an unlit
        LED. The pattern is shown right to left, as it appears on the
        LEDs.

            Pattern     Status
            --------    ------
            11111111    Resetting
            00000001    PROM checksum test
            00000011    Context register test
            00000100    Segment map read/write test
            00000101    Segment map address test
            00000110    Page map test
            00000111    Memory path data test
            00001000    Nonexistent memory bus error test
            00001001    Interrupt test
            00001010    Time-Of-Day clock interrupt test
            00001011    MMU protection/status tests
            00001110    Parity error test #1
            00001111    Parity error test #2
            00010000    Memory test
            10000000    Self-tests have found an error
            01000000    An exception class error occurred

        "Marching ones" (cycling through 10000000, 01000000, 00100000,
        etc.) indicates that Unix is running OK. On power up, it cycles
        through the tests in the chart above, then boots Unix. If LED 7
        (10000000) lights up while the tests are being performed, it
        indicates that the test failed. If LED 6 (01000000) lights up
        with the tests are being performed, it indicates that an
        unexpected error (bus error, address error, unexpected
        interrupt, etc.) occurred during the test. When all tests are
        finished, LED 5 (00100000) starts blinking to indicate that the
        ROM monitor is running and/or Unix is booting.
