How to configure Yubikey to use slot 2?

    The Yubikey I have has two slots in it. If I program it using PwSafe, it seems to put the configuration in slot 1.

    How can I put the configuration in slot 2, so that I can use Slot 1 for something else?

    I have the Yubico programming tool, and I have the 20 byte key needed for the programming, but the Yubico tool (Yubico OTP mode) wants 1-16 bytes public identity (6 bytes default), optional 6 bytes private identity and 16 bytes of secret key.

    Should I just used the first 4 bytes of the PwSafe key as the Private identity (prefixed with 2 bytes of zero) and the remaining 16 bytes as he secret key?
