Win32_BIOS: Discovering Available Properties (Get-CimClass)
Uses Get-CimClass to list every real property and method Win32_BIOS exposes on the current system, instead of guessing from documentation.

.SYNOPSIS
WQL/CIM reference: discovering Win32_BIOS's available properties.
.DESCRIPTION
Before writing a WQL SELECT statement against an unfamiliar class,
use Get-CimClass to list every property and method it actually
exposes on this system — WMI classes vary slightly between Windows
versions, so this beats guessing property names from documentation.
.EXAMPLE
.\BIOSDiscover.ps1
