need help in loading IOS on 3750

Hi all,

can anyone help me on what command i will execute on hyperterminal to copy the IOS from my pc to switch.

My problem is that the switch does not boot because the flash was not found.

I downloaded a flash but i dont know how to copy it from my pc to the switch using hyperterminal.

when i type this command:

switch: copy ?

this will show

usage: copy [-b <buffer_size>] <src_file> <dst_file>

what does buffer size mean and can someonegive me an example command on how to execute that command.

Please someone help me......

Re: need help in loading IOS on 3750

You can try to "download" the IOS via the console cable using XModem, particularly the switch command  "xmodem -r -s 115200".  This command means that the IOS will be loaded into the DRAM (-r switch) and the upload will be using high speed at 115200 bps (-s switch).

Hope this helps.

Please don't forget to rate useful posts.  Thanks.
