I am new to the cisco family, and am presently attending the 3rd semester of Net Academy, so apologies for perceived ignorance. Last night working on Chapter 6 Switch Config, I attempted to boot to a second OS in flash that happens to be of a newer version than the one running on the labs 2950.
the running os was:c2950-3ch2s-mz.120-5.3.wc.1.bin
I change the boot parameters to point to the other file as such...
boot system flash:c2950-6q412-mz.121-19.ea1.bin
Here is the problem, as I have id'd  should have been an 'i'. As a consequence the boot process FAILS!!! CAN'T find the file "DUH" schmuck me!!. The process halts with 'switch:'
I have attempted numerous ways to rectify this problem, BUT to no avail.
Dir flash: reveals that both os are still present....
thanks in advance for any hints on how to restore would be most welcomed... and this schmuck can save a little face..
