Troubleshooting
_______________________________
MAIN MEMORY ERROR
After power up, the monitor remains blank, and there are beep
sounds indicating a main memory failure. In this case, turn off the
power and remove all SIMM modules. Carefully place the modules
back to the sockets and make sure that all the modules are locked by the
locking latches firmly.
In some other cases, the total memory found by the BIOS is
different from the actual amount of memory on board. ( Note that 128K
bytes memory is reserved for the shadow RAM function and will not be
counted by the BIOS). It is also a memory failure and you can follow
the instruction above.
IMPROPER SETTING OF WAIT STATE
If the system hangs after memory test, another possible cause is
the improper setting of the wait state for memory operation. The number
of wait state must match the speed of the DRAM. Reset the CMOS
RAM and set up the wait state. Try to increase the number of wait state.
