.SYNOPSIS
  Retrieve an HP BIOS Setting object by name
 
.DESCRIPTION
  Read an HP-specific BIOS setting, identified by the specified name.
 
.PARAMETER Name
  The name of the setting to retrieve. This parameter is mandatory, and has no default.
 
.PARAMETER Format
  This parameter allows to specify the formatting of the result. Possible values are:
 
    * BCU: format as HP BIOS Config Utility input format
    * CSV: format as a comma-separated values list
    * XML: format as XML
    * JSON: format as JSON
 
  If not specified, the default PowerShell formatting is used.
 
.PARAMETER ComputerName
  Execute the command on specified target computer. If not specified, the command is executed on the local computer.
 
.PARAMETER CimSession
  A pre-established CIM Session (as created by [New-CIMSession](https://docs.microsoft.com/en-us/powershell/module/cimcmdlets/new-cimsessionoption?view=powershell-5.1) cmdlet). Use this to pass a preconfigured session object to optimize remote connections or specify the connection protocol (Wsman or DCOM). If not specified, the function will create its own one-time use CIM Session object, and default to DCOM protocol.

.SYNOPSIS
  Retrieve all BIOS settings
 
.DESCRIPTION
  Retrieve all BIOS settings on a machine, either as native objects, or as a specified format.
 
.PARAMETER ComputerName
  Execute the command on specified target computer. If not specified, the command is executed on the local computer.
 
.PARAMETER Format
  This parameter allows to specify the formatting of the result. Possible values are:
 
    * BCU: format as HP BIOS Config Utility input format
    * CSV: format as a comma-separated values list
    * XML: format as XML
    * JSON: format as JSON
    * brief: (default) format as a list of names
 
.PARAMETER NoReadonly
  When true, don't include read-only settings into the response. Default is false.
 
.PARAMETER CimSession
  A pre-established CIM Session (as created by [New-CIMSession](https://docs.microsoft.com/en-us/powershell/module/cimcmdlets/new-cimsessionoption?view=powershell-5.1) cmdlet). Use this to pass a preconfigured session object to optimize remote connections or specify the connection protocol (Wsman or DCOM). If not specified, the function will create its own one-time use CIM Session object, and default to DCOM protocol.
 
.EXAMPLE
  Get-HPBIOSSettingsList -Format BCU
 
.NOTES
  - Although the function supports BCU, note that redirecting the function's output to a file will not be usable by BCU, because PowerShell will insert a unicode BOM in the file. To obtain a compatible file, either remove the BOM manually or consider using bios-cli.ps1.
  - BIOS settings of type 'password' are not output when using XML, JSON, BCU, or CSV formats.
  - By convention, when representing multiple values in an enumeration as a single string, the value with an asterisk in front is the currently active value. For example, given the string "One,*Two,Three" representing three possible enumeration choices, the current active value is "Two".
  - Requires HP BIOS.

.SYNOPSIS
  Set the value of a BIOS setting
 
.DESCRIPTION
  This function sets the value of an HP BIOS setting. Note that the setting may have various constraints restricting the input that can be provided.
 
.PARAMETER Name
  The name of a setting. Note that the setting name is usually case sensitive.
 
.PARAMETER Value
  The new value of a setting
 
.PARAMETER ComputerName
  Execute the command on specified target computer. If not specified, the command is executed on the local computer.
 
.PARAMETER Password
  The setup password, if a password is active
 
.PARAMETER CimSession
  A pre-established CIM Session (as created by [New-CIMSession](https://docs.microsoft.com/en-us/powershell/module/cimcmdlets/new-cimsessionoption?view=powershell-5.1) cmdlet). Use this to pass a preconfigured session object to optimize remote connections or specify the connection protocol (Wsman or DCOM). If not specified, the function will create its own one-time use CIM Session object, and default to DCOM protocol.
 
.PARAMETER SkipPrecheck
  Skip reading the setting value from the BIOS, before applying it. This is useful as an optimization when the setting is guaranteed to exist on the system, or when preparing an HP Sure Admin platform for a remote platform which may contain settings not present on the local platform.
 
.NOTES
  - Requires HP BIOS.
  - Use single quotes around the password to prevent PowerShell from interpreting special characters in the string.
  - By convention, when representing multiple values in an enumeration as a single string, the value with an asterisk in front is the currently active value. For example, given the string "One,*Two,Three" representing three possible enumeration choices, the current active value is "Two".

.SYNOPSIS
  Clear the BIOS Power-On password
 
.DESCRIPTION
  This function clears any active power-on password.
 
.PARAMETER Password
  The existing setup (not power-on) password. Use Get-HPBIOSSetupPasswordIsSet to determine if a password is currently set. See important note regarding the BIOS Setup Password prerequisite below.
 
.PARAMETER ComputerName
  Execute the command on specified target computer. If not specified, the command is executed on the local computer.
 
.PARAMETER CimSession
  A pre-established CIM Session (as created by [New-CIMSession](https://docs.microsoft.com/en-us/powershell/module/cimcmdlets/new-cimsessionoption?view=powershell-5.1) cmdlet). Use this to pass a preconfigured session object to optimize remote connections or specify the connection protocol (Wsman or DCOM). If not specified, the function will create its own one-time use CIM Session object, and default to DCOM protocol.

.NOTES
  - Requires HP BIOS.
  - Use single quotes around the password to prevent PowerShell from interpreting special characters in the string.
  - On many platform families, changing the Power-On password requires that a BIOS password is active.
  - If BIOS Setup Password is not set, it's required to be first set in order to clear the Power-On password.

<#
.SYNOPSIS
  Check and apply available BIOS updates (or downgrades)
 
.DESCRIPTION
  This function uses an internet service to retrieve the list of BIOS updates available for a platform, and optionally checks it against the current system.
 
  The result is a series of records, with the following definition:
 
    * Ver - the BIOS update version
    * Date - the BIOS release date
    * Bin - the BIOS update binary file
 
  Online Mode uses Seamless Firmware Update Service that can update the BIOS in the background while the operating system is running (no authentication needed). 2022 and newer HP computers with Intel processors support Seamless Firmware Update Service.
  Offline Mode updates the BIOS after reboot and this mode requires authentication (password or payload).
 
.PARAMETER Platform
  The Platform ID to check. It can be obtained via Get-HPDeviceProductID. The Platform ID cannot be specified for a flash operation. If not specified, current Platform ID is checked.
 
.PARAMETER Target
  Execute the command on specified target computer. If not specified, the command is executed on the local computer.
 
.PARAMETER Format
  The file format (XML, JSON, CSV, list) to output. If not specified, a list of PowerShell objects is returned.
 
.PARAMETER Latest
  If specified, only return or download the latest available BIOS version between remote and local. If -Platform is specified, local BIOS will not be read and the latest BIOS version available remotely will be returned.
 
.PARAMETER Check
  If specified, return true if the latest version corresponds to the installed version or installed version is higher, false otherwise. This check is only valid when comparing against current platform.
 
.PARAMETER All
  Include all known BIOS update information. This may include additional data such as dependencies, rollback support, and criticality.
 
.PARAMETER Download
  Download the BIOS file to the current directory or a path specified by SaveAs.
 
.PARAMETER Flash
  Apply the BIOS update to the current system.
 
.PARAMETER Password
  Specify the BIOS password, if a password is active. This switch is only used when -flash is specified.
  - Use single quotes around the password to prevent PowerShell from interpreting special characters in the string.
 
.PARAMETER Version
  The BIOS version to download. If not specified, the latest version available will be downloaded.
 
.PARAMETER SaveAs
  The filename for the downloaded BIOS file. If not specified, the remote file name will be used.
 
.PARAMETER Quiet
  Do not display a progress bar during BIOS file download.
 
.PARAMETER Overwrite
  Force overwriting any existing file with the same name during BIOS file download. This switch is only used when -download is specified.
 
.PARAMETER Yes
  Answer 'yes' to the 'Are you sure you want to flash' prompt. To prevent flashing the BIOS accidentally it is recommended to not specify Yes by default.
 
.PARAMETER Force
  Force the BIOS to update even if the target BIOS is already installed.
 
.PARAMETER BitLocker
  Provide an answer to the BitLocker check prompt (if any). The value may be one of:
    stop - (default option) stop if BitLocker is detected but not suspended, and prompt
    ignore - skip the BitLocker check
    suspend - suspend BitLocker if active, and continue
 
.PARAMETER Url
  Alternate Url source to provide platform's BIOS update catalog (xml)
 
.PARAMETER Offline
  This parameter selects the offline mode to flash the BIOS instead of the default online mode. If specified the actual flash will only occur after reboot at pre-OS environment. This mode is selected by default when downgrading the BIOS version and requires authentication so either a Password or a PayloadFile should be specified.
 
.PARAMETER NoWait
  If specified, the script does not wait for the online flash background task to finish. If the user reboots the PC during the online flash it will complete only after reboot.
 
.NOTES
  - Flash is only supported on Windows 10 1709 (Fall Creators Updated) and later.
  - UEFI boot mode is required for flashing; legacy mode is not supported.
  - The flash operation requires 64-bit PowerShell (not supported under 32-bit PowerShell).
 
  **WinPE notes**
 
  - Use '-BitLocker ignore' when using this function in WinPE, as BitLocker checks are not applicable in Windows PE.
  - Requires that the WInPE image is built with the WinPE-SecureBootCmdlets.cab component.

.SYNOPSIS
  Check and apply available BIOS updates using Windows Update packages
 
.DESCRIPTION
  This function uses an internet service to get the list of BIOS capsule updates available for a platform family, and optionally install the update in the current system. The versions available through this function may differ from Get-HPBIOSUpdate since this relies on the Microsoft capsules availability. This can be delayed due to the Windows Update in-flight processes.
 
.PARAMETER Family
  The Platform Family to check. If not specified, check the current platform family.
 
.PARAMETER Severity
  If specified, returns the available BIOS for the specified severity: Latest or LatestCritical.
 
.PARAMETER Download
  Download the BIOS file to the current directory or a path specified by saveAs.
 
.PARAMETER Flash
  Apply the BIOS update to the current system.
 
.PARAMETER Version
  The BIOS version to download. If not specified, the latest version available will be downloaded.
 
.PARAMETER SaveAs
  The filename for the downloaded BIOS file. If not specified, the remote file name will be used.
  In order to use the downloaded file with Add-HPBIOSWindowsUpdateScripts the name must follow the standard: platform family (3 digit) + underscore + BIOS version (6 digits) + .cab, for instance: R70_011200.cab
 
.PARAMETER Yes
  Answer 'yes' to the 'Are you sure you want to flash' prompt. To prevent flashing the BIOS accidentally it is recommended to not specify Yes by default.
 
.PARAMETER Force
  Force the BIOS to update, even if the target BIOS is already installed.
 
.PARAMETER Url
  Alternate Url source to provide platform's BIOS update catalog (xml).
 
.PARAMETER Quiet
  Do not display a progress bar during BIOS file download.
 
.PARAMETER List
  Display a list with all BIOS versions available for the specified platform.
 
.NOTES
  - Requires Windows group policy support

 .SYNOPSIS
  Get platform name, system ID, or operating system support using either the platform name or its system ID.
 
.DESCRIPTION
  This function retrieves information about the platform, given a platform name or system id. It can be used to convert between platform name and system IDs. Note that a platform may have multiple system IDs, or a system ID may map to multiple platforms.
 
  Currently returns the following information:
 
  - SystemID - the system iD for this platform
  - FamilyID - the platform family ID
  - Name - the name of the platform
  - DriverPackSupport - this platform supports driver packs
 
  Get-HPDeviceDetails functionality is not supported in WinPE.
 
.PARAMETER Platform
  Query by platform id (a 4-digit hexadecimal number).
 
.PARAMETER Name
  Query by platform name. The name must match exactly, unless the -match parameter is also specified.
 
.PARAMETER Like
  Relax the match to a substring match. if the platform contains the substring defined by the -Name parameter, it will be included in the return. This parameter can also be specified as Match, for backwards compatibility.
 
  This parameter is now obsolete and may be removed at a future time. You can simply pass wildcards in the name field instead of using the like parameter.
  The following two examples are identical:
 
    Get-HPDeviceDetails -name '\*EliteBook\*'
 
  is the same as:
 
    Get-HPDeviceDetails -like -name 'EliteBook'
 
.PARAMETER OSList
  Return the list of supported operating systems for the specified platform.
 
.EXAMPLE
  Get-HPDeviceDetails -Platform 8100
 
.EXAMPLE
  Get-HPDeviceDetails -Name 'HP ProOne 400 G3 20-inch Touch All-in-One PC'
 
.EXAMPLE
  Get-HPDeviceDetails -Like -Name '840 G5'
