Using HalDisplayString for Custom Blue Screen of Death

I read for some time somewhere on the Internet that you can make your own BSOD. I don’t remember where, but I know that he has something with a HalDisplayString call, which will switch to bluescreen and print the message. I tried calling HalDisplayString from a simple driver, but nothing happens. I was wondering if anyone could point me in the right direction. Here is the code for the driver.

#include "ntddk.h"
#include "wdm.h"
NTSYSAPI VOID NTAPI HalDisplayString( PCHAR String );
NTSYSAPI VOID NTAPI NtDisplayString( PCHAR String );
DRIVER_INITIALIZE DriverEntry;
NTSTATUS DriverEntry( 
    __in struct _DRIVER_OBJECT  *DriverObject,
    __in PUNICODE_STRING  RegistryPath 
    )
  {

   HalDisplayString("Hello world!");
return 0;  
}

Thanks in advance!

You cannot show the BSOD with this function, it only displays text at boot time until the login screen appears. This link should provide you with some information.

InbvInstallDisplayStringFilter(0); //Not sure but nessecary
InbvEnableDisplayString(1); //Enables printing text to screen
InbvSetScrollRegion(0,0,639,475); //Not sure, would recommend keeping
InbvDisplayString("I print text!\n"); //Prints text
HalDisplayString("And so do I!!!"); //Prints text

return 0;
