/DRIVER (Windows NT Kernel Mode Driver)
Use the /DRIVER linker option to build a Windows NT kernel mode driver.
/DRIVER:UPONLY causes the linker to add the IMAGE_FILE_UP_SYSTEM_ONLY bit to the characteristics in the output header to specify that it is a uniprocessor (UP) driver. The operating system will refuse to load a UP driver on a multiprocessor (MP) system.
/DRIVER:WDM causes the linker to set the IMAGE_DLLCHARACTERISTICS_WDM_DRIVER bit in the optional header's DllCharacteristics field.
If /DRIVER is not specified, these bits are not set by the linker.
If /DRIVER is specified:
/FIXED:NO is in effect. For more information, see /FIXED (Fixed Base Address).
The extension of the output file is set to .sys. Use /OUT to change the default filename and extension. For more information, see /OUT (Output File Name).
