I am fairly new to the pix 501. I've lost my password and I want to default the pix. I've downloaded the tftp server on my PC.I've gone into the monitor mode (which allows me to reset the password). Please explain to can I download the np63.bin image (step by step please). There is a command that I can't find any information on. The command I am referring to is server command.
Question:
Does this command set the server ip address on the tftp that I downloaded on my PC or is there another way of configuring the tftp server Iloaded on my PC?

Review the Cisco CLI documentation found at:

Cisco PIX Firewall Command Reference, Version 6.3 - T through Z Commands  [Cisco PIX Firewall Software] - Cisco Systems

This is for version 6.3.

In Config mode,
tftp-server ip_address path
Show tftp-server
