Update-MyDellBios [[-DownloadPath] <String>] [-Force] [-Reboot] [-Silent] [-ProgressAction <ActionPreference>]
 [<CommonParameters>]
```

## Parameters

| Parameter       | Type              | Required | Description                                                                                                                              |
| --------------- | ----------------- | -------- | ---------------------------------------------------------------------------------------------------------------------------------------- |
| `-DownloadPath` | `String`          | False    | Specifies the directory used to cache the BIOS update and supporting files. The default location is the current user's temporary folder. |
| `-Force`        | `SwitchParameter` | False    | Forces the update workflow even when the installed BIOS version comparison would not normally trigger an update.                         |
| `-Reboot`       | `SwitchParameter` | False    | Adds reboot arguments to the BIOS installer so the system reboots after the silent update completes.                                     |
| `-Silent`       | `SwitchParameter` | False    | Runs the BIOS installer silently without automatically rebooting the system.                                                             |

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
