starting the remainder of the boot process. If the computer passes the POST, the computer may give a single beep (some computers parity circuit failure may beep twice) as it starts and continue to boot. However, dram refresh failure if the computer fails the POST, the computer will either not beep or generate a beep code that asus beep codes tells the user the source of the problem. If your computer has an irregular POST or a beep code not mentioned below, follow the POST troubleshooting steps to determine

PCI Error Messages Error Message FRU/Action PCI device(s) removed 1. One or more PCI add-in devices since last power up: appears to have been removed since PCI vendor ID=xxxx, device the last execution of POST ID=xxxx previously in slot x This could be due to a catastrophic failure of the PCI device rather than its actual physical removal. PCI device(s) added 1. One or more PCI add-in devices since last power up: appears to have been added since PCI vendor ID=xxxx, device the last execution of POST ID=xxxx previously in slot x It may have been moved from another slot. This is not an error. The device was enabled and had resources assigned. Unable to assign requested 1. A req
POST code of 01 means that processor 1 is being tested. Most of the POST diagnostic http://www.etcwiki.org/wiki/Motherboard_2_Digit_BIOS_POST_codes_in_hex cards have 2 digit readouts, corresponding to the list of codes below. Some of these motherboard POST diagnostic tools are based off of the PCI slot (also known as EISA). Other cards have the PCI slot AND a parallel port + USB port (used in conjunction), which allows for most laptops to be tested. Some of the cards that use beep codes these codes: POST Diagnostic Hardware Usage Power down the computer Plug in the POST diagnostic card For the PCI version, just plug into PCI slot For the USB/Parallel version, plug both USB and parallel in (not the PCI part) Power up and read the codes POST Diagnostic Hex Codes The code simply shows you where the computer is in its pci post error startup process. It is the most general codes for general POST and BIOS setups. These POST hex codes will be correct for most computers Code Meaning 01 Processor test 1: Verify CPU status flags?aset, test, clear, and test the carry, zero, sign, overflow flags (fatal) 02 Processor test 2: Write/read/verify all CPU registers, except SS, SP and BP with data patterns FF and 00. 03 Calculate BIOS EPROM and sign-on message checksum; fail if not 0 04 Test CMOS RAM interface and verify battery power Is available. 05 Initialize chips: Disable NMI, PIE, AIE, UEI, SQWV; disable video, parity checking, and DMA: reset math coprocessor, clear all page registers and CMOS RAM shutdown byte: Initialize timers 0, 1 and 2, and set EISA timer to a known state: initialize DMA controllers 0 and 1: initialize interrupt controllers 0 and 1; initialise EISA extended registers. 06 Test memory refresh toggle to ensure memory chips can retain data. 07 Set up low memory; Initialize chipset early; test presence of memory; run OEM chipset initialization routines, clear lower 256K of memory; ena
