Spec
|
5V PCI interface (not compatible with ALIX.1C / ALIX.1D).
During power on self-test (POST), most PC BIOSes will write diagnostic codes to port 80h or
port 84h (jumper selection). Use post4d to display these codes on a dual digit LED display.
Additional LEDs indicate the status of the power supply rails. Convenient business card size. |
