Introduction EP-P80P+ Overview of EP-P80P+ EP-P80P+ is a PCI based Diagnostic & Troubleshooting card for PCI local bus motherboards allowing realtime feedback of system boot status and current state of the PCI Byte Enable/Command signals. The EP-P80P+ can help IT professionals and system engineers in the troubleshooting and repair of nonresponsive systems by obtaining system status direct from port I/O 80H.
EP-P80P+ Diagnostic Card Usage Chapter 2 Diagnostic Card Usage System Voltages Detected These LEDs represent the voltages they represent being present on the PCI bus. The diagnostic card is capable of detecting +5, +3.3, -12, +12V and PCIRST from the PCI bus. PCI Bus C/BE[3::0] # Description Note: A binary 1 below would represent the diagnostic cards corresponding LED being enabled (on), while 0 would be the LED disabled (off).
Diagnostic Card Usage EP-P80P+ Circular Buffer The EP-P80P+ has a built-in circular buffer that contains 32 8-bit wide registers. The register are used for storage of data entries from the host chip. They are indexed 0 through 31, being organized in a form of circular buffer. The previous one to the index (i) register is indexed (i-1), at a lower location; the next one indexed (i+1), at a higher location. The last register index (31) is followed with index (0). All the registers make a cycle.
EP-P80P+ Diagnostic Card Usage Forward/Backword Button Interface The EP-P80P+ also provides two button inputs for use to move RP (Read Pointer) forward (S1 Switch) or backward (S2 Switch) via external push buttons. The RP (Read Pointer) is incremented or decremented and the trace buffer contents pointed by the updated RP (Read Pointer) will be selected for LED display.
Diagnostic Card Usage EP-P80P+ 7-Segment Decoder and Decimal Point (DP) Indicator Within the circular trace buffer, the register contents of the entry pointed by the read pointer (RP) are chosen for display. The 8-bit binary contents are further divided into low and high nibbles, 4 bits each. Alternate selection between both nibbles is periodically conducted according to an internal multiplexed timing clock.
