I'm wondering if there's a way to retrieve information on the BIOS from within Windows 7 without rebooting and going into the BIOS.

I've checked Control Panel\System and Security\System and Device Manager.

A registry key or a built-in GUI or commandline tool is fine, I would also settle for something I have to download if there is no included way.

The more info it can get the better. For instance American Megatrends / Phoenix / Award plus version numbers, dates, whatever.

UPDATE

I have now been able to find some settings in the registry...

  • HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\SystemBiosDate
  • HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\SystemBiosVersion
  • HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\VideoBiosDate
  • HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\VideoBiosVersion

Is there any more detailed information that can also be retrieved from within the OS?

By "information on the BIOS" do you mean information about the BIOS or actual settings within the BIOS? –  Tarek Fadel Aug 14 '11 at 9:05
    
@Tarek Fadel: The former, "information about the BIOS". –  hippietrail Aug 14 '11 at 16:58
    
You can't then. That's up to the manufacturer to implement (and provide software for). I've seen some (e.g. ASUS/Gigabyte) do this on their recent motherboards, but there is no use-for-all program. –  Breakthrough Aug 15 '11 at 0:18

If you don't mind a little vbscript, the code below will return everything that Windows knows about the BIOS. I can't take credit for the code - it comes directly from the Microsoft Scriptomatic app.

Copy the code below into a file called BIOS-Info.vbs (or whatever you want to name it), and then at a command prompt type: cscript BIOS-info.vbs

vbscript code follows:

On Error Resume Next

Const wbemFlagReturnImmediately = &h10
Const wbemFlagForwardOnly = &h20

arrComputers = Array(".")
For Each strComputer In arrComputers
   WScript.Echo
   WScript.Echo "=========================================="
   WScript.Echo "Computer: " & strComputer
   WScript.Echo "=========================================="

   Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
   Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_BIOS", "WQL", _
                                          wbemFlagReturnImmediately + wbemFlagForwardOnly)

   For Each objItem In colItems
      strBiosCharacteristics = Join(objItem.BiosCharacteristics, ",")
         WScript.Echo "BiosCharacteristics: " & strBiosCharacteristics
      strBIOSVersion = Join(objItem.BIOSVersion, ",")
         WScript.Echo "BIOSVersion: " & strBIOSVersion
      WScript.Echo "BuildNumber: " & objItem.BuildNumber
      WScript.Echo "Caption: " & objItem.Caption
      WScript.Echo "CodeSet: " & objItem.CodeSet
      WScript.Echo "CurrentLanguage: " & objItem.CurrentLanguage
      WScript.Echo "Description: " & objItem.Description
      WScript.Echo "IdentificationCode: " & objItem.IdentificationCode
      WScript.Echo "InstallableLanguages: " & objItem.InstallableLanguages
      WScript.Echo "InstallDate: " & WMIDateStringToDate(objItem.InstallDate)
      WScript.Echo "LanguageEdition: " & objItem.LanguageEdition
      strListOfLanguages = Join(objItem.ListOfLanguages, ",")
         WScript.Echo "ListOfLanguages: " & strListOfLanguages
      WScript.Echo "Manufacturer: " & objItem.Manufacturer
      WScript.Echo "Name: " & objItem.Name
      WScript.Echo "OtherTargetOS: " & objItem.OtherTargetOS
      WScript.Echo "PrimaryBIOS: " & objItem.PrimaryBIOS
      WScript.Echo "ReleaseDate: " & WMIDateStringToDate(objItem.ReleaseDate)
      WScript.Echo "SerialNumber: " & objItem.SerialNumber
      WScript.Echo "SMBIOSBIOSVersion: " & objItem.SMBIOSBIOSVersion
      WScript.Echo "SMBIOSMajorVersion: " & objItem.SMBIOSMajorVersion
      WScript.Echo "SMBIOSMinorVersion: " & objItem.SMBIOSMinorVersion
      WScript.Echo "SMBIOSPresent: " & objItem.SMBIOSPresent
      WScript.Echo "SoftwareElementID: " & objItem.SoftwareElementID
      WScript.Echo "SoftwareElementState: " & objItem.SoftwareElementState
      WScript.Echo "Status: " & objItem.Status
      WScript.Echo "TargetOperatingSystem: " & objItem.TargetOperatingSystem
      WScript.Echo "Version: " & objItem.Version
      WScript.Echo
   Next
Next


Function WMIDateStringToDate(dtmDate)
WScript.Echo dtm: 
    WMIDateStringToDate = CDate(Mid(dtmDate, 5, 2) & "/" & _
    Mid(dtmDate, 7, 2) & "/" & Left(dtmDate, 4) _
    & " " & Mid (dtmDate, 9, 2) & ":" & Mid(dtmDate, 11, 2) & ":" & Mid(dtmDate,13, 2))
End Function

I forgot about that, Ive even used that script before. –  Keltari Aug 14 '11 at 23:15

msinfo32.exe will give you some information about the BIOS.

Open Microsoft Word, click the help menu, and then click "About Microsoft Word", Then click "System Info". You will find everything there. Hope that helps.

Ah I see it just runs msinfo32.exe that Keltari talks about in his answer. –  hippietrail Oct 6 '11 at 17:07

I'm not certain but I think that cpuid may do it you can download it from here.
