Subject: WMI query with multiple and/or conditions?

I am using Ruby to write a format disk script.  I am using WMI to
differentiate local logical disks from virtual floppies, CD-roms, and
attached SAN disks.  The differentiation is in the win32_DiskDrive
class, under the "caption" section.  Since this script will be run on
VMs, HP, or Dell, I need it to look for multiple conditions, and I'm not
sure how to do it.  Here is a section of code that works when only
looking for VM disks:

require 'ruby-wmi'
logical_disks = WMI::Win32_DiskDrive.find(:all, :conditions => {
:Caption => 'VMware Virtual disk SCSI Disk Device' } )

Can I add multiple conditions to it, such as two other potential
:Captions?  Some way to do an 'or' in there so it will capture data from
either VMware Virtual Disks, or HP Logical Disks, or Dell Perc, etc?
