That package can not be used to install on a blank harddrive. It can only be used to upgrade an existing recovery partition from a running application partition.
You will need a Recovery CD and will have to boot from the CD.
To get a CD you would need an active Cisco Service for IPS maintenance contract on the sensor, and then you could order the $0 Recovery CD.
Understand that the IDS-4230 is not supported with version 5.0 and higher IPS versions. It is only supported under IDS 4.1. And IDS 4.1 is no longer supported for new Signature Updates.
I am not sure it is worth spending your time to get an IDS version 4.1 image running on your IDS-4230 sensor.
Check just to make sure it is an IDS-4230 and not an IDS-4235. The IDS-4235 is a newer model, and is still supported and receiving signature updates.
You would still, however, need an up to date Cisco Service for IPS maintenance contract for the sensor in order to get recent updates for the sensor.
