Need help adjusting old RAID Array

I have a couple very old servers that have HP Raid Express BIOS software on their raid controllers.  Currently I have 2 72GB drives in a Raid 1 configuration and I would, ideally, like to add a 3rd drive and convert to raid 5.  Is this possible without reinstalling the entire server?

The version of the software is HP NEtRaid Express Ver B.04.02 10-04-01.  I see selections for add configurations, format, clear configuration, etc... I just don't want to chance screwing something up.

In addition, there was an old drive in the server that I would like to remove from the list.  The drive isn't even physically there now, but using "clear configuration" scares me as does 'quick-configure" or "easy configure" or whatever.

Any advice here?

You will need to backup the drives and reinstall it with your new RAID config.
