Padahal lagi nggak ada file IOS yang cocok. Cisco yang laen juga nggak ada. Seharian berburu dapetnya cuma broken link di rapidshare.de. Tapi Alhamdulillah, dapet juga lewat kejelian oom google.

Ubah dulu ahh console baud rate-nya dari default 9600 ke 115,2kbps

Trus downlod deh IOS-nya ke si Cisco. Berhubung masuk ROMMON, downloadnya pake xmodem.
