Troubleshooting Check point A8 A9 AA AB AC B1 00 61-70 Diagnostic LED decoder G=Green, R=Red, O=Orange O Off R Off O Off R G O Off O Off O Off O G O G R Off R Off R O Off Off Off Off - - - - Description Prepare CPU for operating system boot, including final MTRR values. Wait for user input at config display, if needed. Uninstall POST INT1Ch vector and INT09h vector. De-initializes the ADM module. Prepare BBS in Int 19 boot. End of POST initialization of chipset registers. Save system context for ACPI. Pass control to OS Loader (typically INT19h). OEM POST Error. This range is reserved for chipset vendors and system manufacturers. The error associated with this value may be different from one platform to the next. Bootblock initialization code checkpoints The Bootblock initialization code sets up the chipset, memory, and other components before system memory is available. The following table provides the diagnostic LED code for these checkpoints and describes the type of checkpoints that may occur during the bootblock initialization: Check Diagnostic LED decoder Description point G=Green, R=Red, O=Orange Before R R Off O Early chipset initialization is done. Early super I/O initialization D1h is done, including RTC and keyboard controller, NMI is disabled. D1 R R Off O Perform keyboard controller BAT test. Check if waking up from power management suspend state. Save power-on CPUID value in scratch CMOS. D0 R R Off R Go to flat mode with 4 GB limit and GA20 enabled. Verify the bootblock checksum. D2 R R G R Disable CACHE before memory detection. Execute full memory sizing module. Verify that flat mode is enabled. D3 R R G O If memory sizing module not executed, start memory refresh and do memory sizing in Bootblock code. Do additional chipset initialization. Re-enable CACHE. Verify that flat mode is enabled.
