Support for multiple BIOS passwords

[amitgulyani]

We have multiple BIOS passwords (different BIOS passwords for different sites), will this script support this scenario? If not, how can we get it working?

Since not every HP flash utility supports being passed a password, we ended up adding a password removal step in our task sequence before applying HP BIOS', then a password add step after the reboot.

We ended up finding not every model removes the password successfully, so we ended up forking the HP script and adding support for a password parameter that leverages the HpqPwd utility present in every BIOS package we've seen. This generates a password bin file on the fly from the supplied password and uses that with the HP upgrade tool.
