I know, but I don't have access to this PIX, for using the recovery password procedure, I need to know the IOS version.

You don't need to be in enable mode to do a show version if that's what you mean. You will need to be connected to the console to do the password recovery as you probably know.

If you reboot/power off your Firewall and connected into the console it will show you what version it boots. From there you will be able to select the correct file for uploading to the PIX.

You all need to understand that when you're doing a password recovery that you're NOT deleting the configuration. You're simply going around the conventional method of loading it so that you may modify its settings. The setting you're concerned with during the recovery is the password. So, you'll change the password and reload the firewall. This will load up the configuration with your password modification.

Again, you're not removing the startup config, just modifying it with regards to the password.
