The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly., 04h = FASTC, 20h = FASTX XMSsee Extended Memory Specification)

 14h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	total number of writes (only counted when staging enabled)
 18h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	number of physical disk writes (only when staging enabled)
