Post Diagnostic Card Codes List
a POST card is a plug-in interface card that displays progress and error codes motherboard post card generated during power-on self-test (POST) of a computer. It is used to troubleshoot computers that do not start up. Contents 1 Working debug card error codes and solution pdf principle 2 Operation 3 Usage scenarios 4 See also 5 References Working principle[edit] At a minimum, if the CPU, BIOS, and the I/O interface upon which the POST card relies are all working, a POST card can https://www.youtube.com/watch?v=f_WhFDNL_z0 be used to monitor the system's Power-On Self Test (POST), or to diagnose problems with it. The system sends two-hexadecimal-digit codes to a specified I/O port (usually 80hex) during startup, some indicating a stage in the startup procedure, others identifying errors. The description for each code must be looked up in a table for the particular BIOS. For example, for the 1984 IBM PC/AT code 1D is issued when about to Determine Memory Size https://en.wikipedia.org/wiki/POST_card Above 1024K, and code 2D in the event of 8042 Keyboard Controller Failure, 105 System Error. If startup does not complete successfully, either an error code, or the code of the last operation, is available. POST cards provide information even when a standard display is not available, either because connecting a monitor is impractical, or because the failure occurs before the video subsystem is operational. Operation[edit] POST cards are inserted into an expansion slot, and are available in ISA (also supporting EISA), PCI, parallel port, and other variants (Mini PCIe, for laptop computers, is supported by some cards, but with restrictions). A typical card for desktop computers has both an ISA interface on one edge, and PCI on another; a card for laptop computers has both a miniPCI and a parallel port connector (plus USB to supply power). Information on the meaning of POST codes for different BIOSes is needed to interpret the codes. This is supplied with cards, but becomes dated as later BIOSes are issued; up-to-date information is available on manufacturers' and independent websites.[1] In addition to displaying numeric codes, many cards monitor power supply voltages, clock and oscillator signals, reset signal, and other parameters.[2] Usage scenarios[edit] Two POST seven-segment displays integrated on a computer motherboard POST cards for PCs, while originally high-priced, cost from just

Check the keyboard controller or clock generator if a failure occurs Initialize Chipsets Check the BIOS, CLOCK and chipsets Reset Determination The BIOS reads the bits in the keyboard controller to see if a hard or soft reset is required (a soft reset will not test memory above 64K). Failure could be the BIOS or keyboard controller ROM BIOS Checksum The BIOS performs a checksum on itself and adds a preset factory value card error codes that should make it equal to 00. If a failure occurs, check the BIOS chips Keyboard Test A command is sent to the 8042 keyboard controller which performs a test and sets a buffer space for commands. After the buffer is defined the BIOS sends a command byte, writes data to the buffer, checks the high order bits of the internal keyboard controller and issues a No Operation (NOP) command CMOS Shutdown byte in CMOS RAM offset 0F is tested, the BIOS checksum calculated and diagnostic byte 0E updated before the CMOS RAM area is initialized and updated for date and time. Check the RTC and CMOS chip or battery if a failure occurs DMA (8237) and PIC (8259) Disable The DMA and Programmable Interrupt Controller are disabled before the POST proceeds and further. Check the 8237 or 8259 chips if a failure occurs Video Disable The video controller is disabled and port B initialized. Check the video adapter if a failure occurs Chipset Initialized and Memory Detected Memory addressed in 64K blocks. Failure would be in the chipset. If all memory is not seen, failure could be in a chip in the block after the last one seen PIT Test The timing functions of the 8254 Programmable Interrupt Timer are tested. The PIT and RTC chips normally cause errors here Memory Refresh PIT's ability to refresh memory is tested. If an XT,
