Corrupt bin fails to boot

We have an cisco soho 91 at my office wich stopped responding when we got back to work one morning.

All leds on it was lit on the "lan side" (it has four lan ports) but it was not allowing any traffic to get through. After shutting the router on/off without positive effect I connected my pc to the console port and saw that the router was in rommon.

I did a reset and saw this:

The result of "dir flash:":

Does this mean that the bootfile is corrupt? Is the only way to fix this by downloading another bin? How could it happen?

Ronsta,

Clearly your software is corrupted. You need to load a new software using the X-modem procedure. Check the following links for the procedure details:
