====== YAMON ======
YAMON è il PROM monitor fornito da MIPS technologies, ed adottato da SIGMA per la propria piattaforma.

Sul STB è presente una versione modificata da Pirelli, che ha aggiunto alcune funzioni per utilizzare YAMON come secure bootloader: prima di bootare un binario, verifica che sia firmato con una chiave privata Pirelli; questo significa che non è possibile far caricare una partizione flash non firmata.

Probabilmente è possibile sostituire la versione modificata, presente sull'HY100, con una standard, ad esempio [[http://hy100wiki.algasystems.net/files/unsigned_yamon.zip|questa versione]].

Questa è la lista dei comandi disponibili una volta [[yamon_break|ottenuto l'accesso al prompt]].
