Introduction
------------
Hard Drivers Read Only is a TSR utility used to protect your hard disks
(and software floppy disks) against writing and formatting. The utility works
in protect or normal mode. Switch between modes is done by <CTRL+SCROLL LOCK>
key combination. The default mode is the protect mode. Change between the modes
is signaled by a beep through PC Speaker:
- protect mode is the high beep
- normal mode is the low beep
When you are formatting or writing to protected disk, the utility returns a
DOS write-protected message.

Note: Under new HDs and BIOSes witch uses DMA util not works.
