Scheda di diagnostica per PC del POST-Code per bus ISA e PCI
Scheda di diagnostica delle operazioni di POST - ovvero delle operazioni di inizializzzione della scheda madre e del BIOS a seguito dell'accensione, utile per la ricerca di criticità in caso di malfunzionamento del PC. Dispone sia del vecchio slot ISA a 8 bit ormai scomparso, e del più moderno slot PCI. Sulla scheda sono presenti i LED che segnalano la presenza delle varie linee di alimentazione: + / - 12 Volt, +5 Volt, + 3,3 Volt - la rpesenza del clock di sistena, di Reset e di stato. E' presente inoltre un dis'play a 4 cifre che visualizza in tempo reale i vari codici di POST generati dalla scheda madre, le prima 2 cife mostrano il codice di errore corrente, mentre le ultime due cifre indicano il codice di errore precedente.
