Good afternoon.

I am new to PB. My primary language is not US/UK. I am using Google Translate.

I am practicing writing code to distinguish whether Windows is booting using FW MBR or UEFI.

Code: Select all

Enumeration FIRMWARE_TYPE
  #FirmwareTypeUnknown
  #FirmwareTypeBios
  #FirmwareTypeUefi
  #FirmwareTypeMax
EndEnumeration

Prototype.i Get_FirmwareType()

If OpenLibrary(0, "Kernel32.dll")
  FW.Get_FirmwareType = GetFunction(0, "GetFirmwareType")
  Debug FW()
EndIf

The functions return value is an error code. You need to specify your structure as parameter.

How? Can you explain it to me?

If you read what you post as link, then you will notice why it is not working.
This function has a parameter

The parameter is a pointer <-> integer

Code: Select all

Enumeration FIRMWARE_TYPE
  #FirmwareTypeUnknown
  #FirmwareTypeBios
  #FirmwareTypeUefi
  #FirmwareTypeMax
EndEnumeration

Prototype.i Get_FirmwareType(*FirmwareType)

If OpenLibrary(0, "Kernel32.dll")
  FW.Get_FirmwareType = GetFunction(0, "GetFirmwareType")
  
  Define FirmwareType.i
  
  If FW(@FirmwareType)
    Debug FirmwareType
  Else
    Debug "Error"
  EndIf
EndIf

Really, you need to understand what you are reading. And you need to read, read , ...
