Microserver N54L Firmware 2013
Purtroppo l’accesso il firmware dei Microserver HP è stato ristretti ai sottoscritto di di un contratto di assistenza attivo.
Questo è chiaramente fastidioso e francamente incomprensibile.
Per questo motivo qui di seguito trovate i files originali più un firmware modificato che permette di avere un BIOS più personalizzabile e permette di sbloccare la velocità delle ulteriori due porte SATA presenti a bordo per chi vuole utilizzarle con set di dischi superiore a 4.
Una volta utilizzato il tool HP per creare l’USB stick con autoboot potete effettuare il flash del firmware (non viene richiesta interazione umana per cui è possibile effettuare l’operazione su di un NAS senza monitor e tastiera).
Potete anche sosituire sull’USB stick il file del Firmware con questo:
O41100113.ROM
presente nel file zip per avere le funzionalità aggiuntive (testato su un N45L).
