The original code just supported recording and displaying patterns suitable for use with the Linux BadRAM extension or GRUB badram command. With some minor changes it can be made to record address ranges and display them either in the format used by the Linux memmap boot command line option or as a simple list of memory page numbers (which can be used with the Windows bcdedit program).
