[<CommonParameters>]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 -DisableNumLockThis 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.
| Type: | CimSession[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ComputerName
Specifies one or more Hyper-V hosts for which the BIOS is to be configured. NetBIOS names, IP addresses, and fully qualified domain names are allowable. The default is the local computer. Use localhost or a dot (.) to specify the local computer explicitly.
| Type: | String[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Confirm
Prompts you for confirmation before running the cmdlet.
| Type: | SwitchParameter |
| Aliases: | cf |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Credential
Specifies one or more user accounts that have permission to perform this action. The default is the current user.
| Type: | PSCredential[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-DisableNumLock
Specifies that NumLock is to be disabled in the BIOS of the virtual machine to be configured.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-EnableNumLock
Specifies that NumLock is to be enabled in the BIOS of the virtual machine to be configured.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Passthru
Specifies that an Microsoft.HyperV.PowerShell.Bios object is to be passed through to the pipeline representing the BIOS to be configured.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-StartupOrder
Specifies an array of boot devices representing the boot order in the BIOS of the virtual machine. The boot devices are specified as members of the BootDevices enumeration (CD, IDE, LegacyNetworkAdapter, Floppy).
Note: The other BootDevices enumeration values of VHD and NetworkAdapter are for Generation 2 VMs only, and are not valid with this cmdlet.
| Type: | BootDevice[] |
| Accepted values: | Floppy, CD, IDE, LegacyNetworkAdapter, NetworkAdapter, VHD |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-VM
Specifies the virtual machine for which the BIOS is to be configured.
| Type: | VirtualMachine[] |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-VMBios
Specifies an array of BIOS objects. The cmdlet configures the BIOS that you specify for the virtual machines. To obtain a BIOS object, use the Get-VMBios cmdlet.
| Type: | VMBios[] |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-VMName
Specifies the name of the virtual machine for which the BIOS is to be configured.
| Type: | String[] |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
| Type: | SwitchParameter |
| Aliases: | wi |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
Outputs
None
Default
Microsoft.HyperV.PowerShell.Bios
If -PassThru is specified.
