PCI POST diagnostic card

This PCI POST card displays four-digit error codes during the system power-on self-test. It is designed for technicians and enthusiasts who need to troubleshoot motherboards that fail to boot or show no video output. The card plugs directly into a PCI slot and provides immediate visual feedback without requiring a working display or operating system.

Red LED display and plastic-metal build

The unit measures 80×60 mm and features a red LED readout of 50×20×7 mm for clear code visibility. A CE-marked plastic and metal construction handles repeated insertion and removal during bench testing. The package includes the analyzer card and an English user manual that lists the error-code definitions for supported BIOS types.

Check PCI slot availability and BIOS compatibility

Verify that the target motherboard has a free PCI slot — not PCI Express — before ordering. The card supports Phoenix BIOS 4.01 to 6.0, AMI BIOS 6.24 and Award BIOS 4.51 on desktop platforms, plus specific Dell and Toshiba models listed in the specifications. Systems using newer UEFI-only firmware or lacking a legacy PCI slot will not work with this tool.
