In 32 and 64 bits it is forbidden (by the operating system) to directly access to memory addresses contents.

You have to use Windows API functions to access the information that you are looking for

You can use wmi to get these informations

Code (fw): Select all Collapse

TRY
    oWmi := CreateObject( "wbemScripting.SwbemLocator" )
  CATCH oErr
    oWmi := nil
    lError := .t.
    cError := oErr:Description
  END

  IF !lError
    objWMI:= ::oWmi:ConnectServer() // (strComputer, "root\cimv2")
  ENDIF

oBios := objWMI:ExecQuery( "Select * FROM Win32_BIOS" )

FOR EACH oData IN oBios
    cManufacturer  := oData:Manufacturer
    cName          := oData:Name
    cSerialNumber  := oData:SerialNumber
    dReleaseDate   := StoD (SubStr(oData:ReleaseDate,1,8))
    cVersion       := oData:SMBIOSBIOSVersion
    cRevison       := oData:Version
NEXT

kind regards

Stefan

You can read that info from the registry:

HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\

SystemBIOSDate
SystemBIOSVersion
VideoBIOSDate

All the source code in FWH\source\winapi*.c are example of calls to the Windows API functions
