help istallazione ios su router Cisco 3620

[oloap88]

ciao a tutti,
ho recentemente comprato due router cisco 3620 su ebay.
Ovviamente è stata una sola, i problemi sono iniziati.
uno è in boot loop quindi ho deciso di concentrarmi sull'altro.

Il precedente possessore ha deciso di fare un bel

erase flash

prima di spedirlo... quindi mis ono trovato a dover istallare l'ios da rommon>
ovviamente non avendo connettività ho dovuto usare xmodem via seriale.
riporto quello che è successo:

rommon 11 > xmodem -r c3620-ik9s-mz.122-7b.bin

rommon 1 > ?



in pratica da quello che ho capito manca la memoria... ma quale memoria? la flash? o la nvram?
nel caso sia la flash il router ha due slot pcmcia sul fronte.
cosa posso fare per fare in modo di riuscire ad usare almeno uno dei due router? quello in boot loop è sacrificabile visto che l'ho pagato 1,5€...
grazie a tutti per l'aiuto!!!
