Repeating High/Low CPU failure- Either the CPU is not seated properly or the CPU is damaged. Credit to John Palmer. Replace the motherboard 12 short CMOS RAM shutdown register failure THE real time clock/CMOS IC failed. Failure would indicates invalid CMOS setup, cache controller or chip failure NMI Unexpected Exceptions A final check for unexpected exceptions before giving control to the Int 19 boot loader.
You can use this location along with the memory map for your system to find and replace the bad memory chips Memory parity Error at... This beep pertains to Compaq Deskpro systems 1 long never ending beep Memory error- Bad RAM. Write CMOS The BIOS is waiting to write the CMOS values from Setup to CMOS RAM. If ESCD is valid, take into consideration of the ESCD's legacy information; Onboard clock generator initialization.
Replace the IC if possible 2-1-3 64KB RAM failure Bit 2; This data bit on the first RAM IC has failed. LED light flashes can provide indication. If failure does occur suspect the BIOS or RTC Video ROM Video ROM is initialized which performs an internal diagnostic before returning control to the system BIOS. Dma Controller You can use this location along with the memory map for your system to find and replace the bad memory chips.
Replace the IC if possible 2-1-4 64KB RAM failure Bit 3; This data bit on the first RAM IC has failed. Replace the IC if possible 4-2-4 Unexpected interrupt in protected mode- This is a CPU problem. Jul 13, 2008 #17 chypsas TS Rookie Posts: 16 Excellent work, thanks Sep 7, 2008 #18 Rolando TS Rookie Thanks This is absolutelly FANTASTIC.Thanks a lot and keep it up. Failure is normally due tot he ROM BIOS CMOS Test A test of the CMOS chip which should also detect a bad battery.
Press any key to reboot the system Press ESC to skip memory test You can press ESC to skip the full memory test PRESS F1 TO DISABLE NMI, F2 TO REBOOT Cmos Battery Replace the video adapter 1 long, 5 short 64KB memory failure A failure has occurred in the base 64KB of memory. Initialize DMA controller 0 and 1. If you haven't set the motherboard for burn-in mode, there is a short in the circuitry Initialize Chipset BIOS clears all DMA registers and CMOS status bytes 0E and 0F.
Disable video, parity checking, DMA. Some BIOS POST messages you will see in all UPPER CASE and some will be found in a mix of UPPER and lower case. Ami Bios Beep Codes Failure is normally the video controller (6845) or an improper setting of the motherboard or CMOS PIT BIOS tests the functionality of channels 0, 1, and 2 in sequence. Asus Beep Codes For example, in you insert a Promise Ultra-66 card but do not connect a hard drive to it, you will get the beep code.
