H136516 - NO VIDEO OR 210 POST ERROR IN PC 300 W/32MB SYMPTOM: IBM PC 300 Series 6577 and 6587 systems may exhibit either of the following symptoms on systems containing an IBM 16Mb DIMM and 2 IBM 8Mb Non-Parity EDO 60ns SIMMs: 1) 1 to 5 beeps during POST, no video and a system hang condition prior to loading the operating system. 2) The system displays POST and performs an incorrect memory count resulting in a 210 POST error code. Both failure symptoms are solid and recurring. This is not an intermittent failure. PROBLEM ISOLATION AIDS: Affected systems contain a total of 32Mb in the following combination ONLY: - One IBM 16Mb DIMM, FRU P/N42H2779 manufactured for IBM by Hyundai. Affected Hyundai 16Mb DIMMs contain the following bar code headers: J10CV or J11UW - Two IBM 8Mb 60ns Non-Parity SIMMs, FRU P/N42H2794, manufactured for IBM by IMD. If the system contains only the Hyundai 16Mb DIMM, there is no failure. If the system contains a pair or more of the 8Mb IMD SIMMs with no DIMM installed, there is no failure. No other combination of DIMMs or SIMMs regardless of size, parity or non parity exhibit this failure. NOTE - SOME SYSTEMS MAY CONTAIN A COMBINATION OF ONE 16MB DIMM AND TWO 8MB SIMMS FROM MANUFACTURERS OTHER THAN HYUNDAI AND IMD. THOSE SYSTEMS WILL NOT EXHIBIT THIS FAILURE. FIX: If the system is exhibiting the failure symptom stated above AND contains a combination of a 16Mb DIMM manufactured for IBM by Hyundai and two 8Mb SIMMs manufactured for IBM by IMD, replace the 16Mb DIMM, FRU P/N42H2779. If the failure persists, continue normal problem determination.
