Sorry for reviving this topic, but I have exactly the same post code and have found no information about POST-sequence.
In TPS for S5000PSL there is only a table "Diagnostic LED POST Code Decoder", but flow-chart of test sequence is not given!
My server is running more the 6 years, and all happened after CPU upgrade attempt from 5110 to L5335 (SLAEN). I've checked PBA and BIOS/FRU/BMC versions before - all OK (BIOS101, BMC66, FRUSDR48). After I changed CPUs, the server was working for several hours (see BIOS photo after upgrade). Then I reconnect AC cable to put server into closet and it did not boot even to BIOS. The last POST-code - 0x98h Resetting the mouse. I can switch-off server by front-panel button, it means chipset is programmed by BMC. Several procedures ran indicate CPU/memory/buses are working properly.
What I checked:
- switched to alternative BIOS bank by jumper
- leave first CPU (old one, Xeon 5110) and single DIMM in A1 slot (several DIMMs tested in this slot)
- disconnected all SATA, IDE, PS/2, VGA, USB cables
- check if it boots in BMC force update mode (by corresponding jumper)
nothing helps
What I need is at least POST flowchart, cause I even do not know if 0x98h code is set after or before mouse initialization procedure. If after, then I need to know what should be the next test. By the way, I can see keyboard reset in previous test 0x95h. 0x94h. AFAIK it means CPU is executing procedures properly.
Please, help with info about S5000PSL POST procedures or, may be there is a way to use BMC (evidently it works OK - I can see solid green led). I tried to connect to EPM-com port, but there is no any debug messages or codes. All I had was code 0x98h with funny failure reason "Mouse reset"...
My decoding of startup sequence:
Time Code Procedure
0:33 0x21h Initializing a chipset component
0:37 0xA4h undocumented ??
0:37 0x21h Initializing a chipset component
... many "blinkings"
0:43 0xB0h Resetting fixed media device
0:55 0x11 Host processor cache initialization (including AP)
1:00 0xE4h Entered EFI driver execution phase (DXE)
1:03 0x13h SMM initialization
1:05 0x50h Enumerating PCI busses
1:06 0x95h Instructing keyboard controller to run Self Test (PS/2 only)
1:07 0x94h Clearing keyboard input buffer
1:08 0x98h Resetting the mouse

PS yes, I know it's too late for S5000PSL
