Description
The Set-VMBios cmdlet configures the BIOS of a Generation 1 virtual machine. Note: This cmdlet does not operate with Generation 2 virtual machine. If attempted, the cmdlet throws an error.
Examples
Example 1
PS C:\> Set-VMBios TestVM -DisableNumLock
This example disables the NumLock key by default on virtual machine TestVM.
Example 2
PS C:\> Set-VMBios TestVM -StartupOrder @("Floppy", "LegacyNetworkAdapter", "CD", "IDE")
This example configures virtual machine TestVM to check for a boot device in the following order: floppy disk, network, CD drive, hard disk.
Parameters
-CimSession
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
