| Code | Meaning (from Intel POST Code Reference) | |------|--------------------------------------------| | | Processor internal test – starting CPU initialization. If stuck, indicates CPU or power issue. | | 21 | OEM memory detection / initial memory sizing. Very common early step. | | b6 | Not standard Intel. Likely a vendor-specific or misread code. In AMI BIOS (used on some Intel boards), b6 is “Clean-up of NVRAM.” | | e1 | Not standard. Possibly “E1” meaning “Runtime APIC initialization” or in some boards, “Error in SMM (System Management Mode).” | | e2 | Could be “E2” – “Initialize multi-processor AP” or in some cases “Invalid password” (rare). | | er | Most likely an error display on a 2-character debug LED – meaning “ER” = General Error / Halt. Could be “E2” misread as “Er.” | Physical Inspection Look for a small barcode label
