The Flash memory will be in Read/Write mode when you boot into boot mode.  This will allow you to load a new image into the flash.

See below.  I suggest you check out the 2 URL's for more details on how to load a new image.  It can be tricky the first time.  

This can be done as follows:
   Router> enable
   Password: password
   Router#
   Router# conf t
   Enter configuration commands, one per line. End with CNTL/Z.
   Router(config)# config-register 0x2101
   Router(config)# ^Z
   Router#
   Router# wr mem

   Router# reload

   Router(boot)>

Take a look at the following - http://www.sdnp.undp.org/rc/areas/tech/setup/cisco-upgrade.html

Greenclock,

Thank you for your answer but maybe I should have worded my question differently. I have reloaded IOS images many times to different routers with the [copy tftp command]. I am looking for the command /s to change the flash from read to read/write when viewed with [sh ver]. I have seen it with the config. reg set to 0x2102. Thanks

No probs...

The very thing you were asking had me baffled for a while when I got hold of my first 25xx.  Just glad I could be of help.

Thanks for the points..
