Detail :
Customers experiencing solid or intermittent errors during POST or load of the operating system with one of the 9546 models identified in the FEATURES section of this ECA should call the IBM PCCO Help Center. They will verify the failing condition and replace their current 0MB or 8MB Adapter with a new 0MB DIMM adapter FRU P/N 83H7124 or a new 8MB (soldered on memory) DIMM adapter FRU P/N 83H7126 that has been released to correct this condition.
Systems with system boards that are not identified in the tip can utilize the old or new level of DIMM adapters.
The following are examples of some of the failing conditions.
The system hangs during POST with a flashing cursor on a dark screen. The Fixed Disk icon may also flash on the LCD indicator Assembly.
The operating system starts, but encounters memory problems such as, "himem.sys has found bad ems memory @ location xxxx" with a following message that "himem.sys is not loaded".
The operating system starts, but hangs with the operating system logo screen displayed.
If the above conditions are met, remove the Memory DIMM(s) and reboot the system. Note: Intermittent conditions normally occur 3 out of 10 times during cold boots.
