Few days ago when I reloaded my Cisco 3725, it didn’t come up, I tried many times, I found that it can not be the IOS problem, though it could’t be found by the router, I finally recovered that problem, my Cisco Instructor, Charles, gave me useful hints to fix my problem.
Here I want to tell you about useful commands in ROMMON mode which help you to run your IOS from flash: memory, dir and boot , see the examples below:

rommon2> dir flash:
       File size         Checksum  File name
5358032 bytes (0x51c1d0) 0x7b16    c2600-i-mz.122-10b.bin
rommon3> boot flash:c2600-i-mz.122-10b.bin

You can find more information about those commands in here.
