POST Code: A5A4 To resolve this issue, clear the SEL, then perform a CMOS Clear CMOS Clear Procedure: Power down the server; do not remove AC power. Open the server and move the jumper from the default operating position (pins1-2) to the “clear” position (pins 2-3). Wait 5 seconds. Move the jumper back to the default position (pins 1-2). Close the server system and power up the server. CMOS is now cleared and can be reset by going into the BIOS setup.

What generates an NMI? What does it mean? The first question is easy to answer but https://blogs.msdn.microsoft.com/oldnewthing/20070227-00/?p=27843 doesn't actually shed much light: Any device can pull the NMI line, and https://docs.oracle.com/cd/E19469-01/819-4363-12/A_error_handling_x4540.html that will generate a non-maskable interrupt. Back in the Windows95 days, a few really cool people had taken the ball-point pen trick one step further: They had a special expansion card in their computer with a cord coming out the back. At the end of the cord was a momentary switch like the hardware error one you might see on a quiz show. If you pressed it, the card generated an NMI. No fumbling around with ball-point pens for these folks, no-ho! (To be honest, I had two of these. One of them was a simple NMI card, triggered by a foot pedal! The other was really a card with a high-resolution real-time clock that could be used for performance computer hardware errors analysis. I used the NMI button far more often than the timer...) In practice, the only device that generates an NMI (on purpose) is the memory controller, which raises it when a parity error is detected. The non-geek explanation of a parity error: Your memory chips are acting flakey. Here's what a parity error looks like. It shows up as a mysterious "Hardware Malfunction" error. Now, it's possible that a device may be generating an NMI by mistake. For example, in Wendy's case, it may have been due to damaged caused by overheating. If you suspect your memory chips, you can run a memory diagnostic tool to see if it can find the bad memory. My colleague Keith Moore reminded me that paradoxically, on the IBM PC-AT, you could mask the non-maskable interrupt! This definitely falls into the category of "Unclear on the concept." The masking was done in hardware that could be configured via some magic port I/O. It prevented the NMI from reaching the CPU in the first place. (NMI is still not maskable in the CPU.)

Errors (PERR) System Errors (SERR) Handling Mismatched Processors Hardware Error Handling Summary Uncorrectable Errors This section lists facts and considerations about how the server handles uncorrectable errors. Note - The BIOS ChipKill feature must be disabled if you are testing for failures of multiple bits within a DRAM (ChipKill corrects for the failure of a four-bit wide DRAM). The BIOS logs the error to the SP system event log (SEL) through the board management controller (BMC). The SP's SEL is updated with the failing DIMM pair's specific bank address. The system reboots. The BIOS logs the error in DMI and SP event logs. Note - If the error is on low 1MB, the BIOS freezes after rebooting. Therefore, no DMI log is recorded. An example of the error reported by the SEL through IPMI 2.0 is as follows: When low memory is erroneous, the BIOS is frozen on pre-boot low memory test because the BIOS cannot decompress itself into faulty DRAM and execute the following items: ipmitool> sel list 100 | 08/26/2005 | 11:36:09 | OEM #0xfb | 200 | 08/26/2005 | 11:36:12 | System Firmware Error | No usable system memory 300 | 08/26/2005 | 11:36:12 | Memory | Memory Device Disabled | CPU 0 DIMM 0 When the faulty DIMM is beyond the BIOS's low 1MB extraction space, proper boot happens: ipmitool> sel list 100 | 08/26/2005 | 05:04:04 | OEM #0xfb | 200 | 08/26/2005 | 05:04:09 | Memory | Memory Device Disabled | CPU 0 DIMM 0 Note the following considerations for this revision: Uncorrectable ECC Memory Error is not reported. Multi-bit ECC errors are reported as Memory Device Disabled. On first reboot, BIOS logs a HyperTransport Error in the DMI log. The BIOS disables the DIMM. The BIOS sends the SEL records to the BMC. The BIOS reboots again. The BIOS skips the faulty DIMM on the next POST memory test. The BIOS reports available memory, excluding the faulty DIMM pair.

FIGURE D-1 DMI Log Screen, Uncorrectable Error Correctable Errors This section lists facts and considerations about how the server handles correctable errors. During BIOS POST: The BIOS polls the MCK registers. The BIOS logs to DMI. The BIOS logs to the SP SEL through the BMC. The feature is turned off at OS boot time by default. Solaris support provides full self-healing and automated diagnosis for the CPU and Memory subsystems.
