PHYSICAL CHECK: Systems in the FEATURES section of this ECA containing DIMM adapter FRU P/N39H6229 (8MB) or DIMM adapter FRU P/N46H6023 that experience intermittent hangs when used with the following system boards and 1 or 2 of any manufacture's DIMMs. The number used to identify the system board is located on a label in the Ultra Bay compartment between the second battery connector and the Ultra Bay connector. It can be seen without using tools. Open the keyboard and remove the component in the Ultra Bay. It will be a diskette drive, CD Rom drive, Hard Drive Battery. NOTE: this is a Manufacturing part number NOT a FRU part number.

Check and install or notify customer of the need for this direct shipment CRU when applicable. CONCURRENT: NONE DETAIL: Customers experiencing solid or intermittent errors during POST or load of the operating system with one of the 9546 or 9547 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/N83H7124 or a new 8MB (soldered on memory) DIMM adapter FRU P/N83H7126 that has been released to correct this condition. Customers that are not having the above conditions can also receive a new level DIMM adapter card if their system board requires it. The new part number DIMM adapter will operate correctly in any level system, but its primary design is to correct intermittent or solid hangs that occur on the system boards identified in the PHYSICAL CHECK area of the ECA. The DIMM Adapter FRU will be sent directly to the customer. They are Customer Replaceable Units (CRUs) that are easily installed. NOTE: The Help Center Telephone numbers are listed at the end of the DETAIL section. NOTE: The above Help Center action does NOT require the use of this ECA. Systems with system boards that are not identified in the PHYSICAL CHECK area of the ECA can utilize the old or new level of DIMM adapters. These systems do NOT require this ECA. The following are examples of some of the failing conditions. o 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. o 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". o 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. =============================================================== |NOTE: This ECA should only be installed during the following | | situations: | =============================================================== This ECA can be installed by a CE or Dealer following normal ECA terms and conditions if it qualifies under the FEATURES and PHYSICAL CHECK areas and one of the following conditions occur: 1. The system currently being serviced has an intermittent or solid hang condition. 2. The customer requires servicer installation instead of a direct CRU (Customer Replaceable Unit) shipment. 3. The IBM geography does not support direct CRU shipments to customers. WORLD WIDE HELP CENTERS THAT SUPPORT CRU SHIPMENT TO CUSTOMERS.
