Purpose
*******

1. Naive users sometimes meddle with CMOS settings.  We need a
11111111111111111
fast way to put the scores of subtle CMOS configuration settings
back the way they were.
222222222222222
2. Power surges can corrupt CMOS.  We need a way for a naive
user to quickly restore all the CMOS settings.

3. If the battery fails, the contents will be lost.  We need a
way to restore a known working CMOS configuration.


Syntax
******

There are three utilities in the CMOS suite:

CMOSSAVE.COM  A:Myfile.Sav
IF ERRORLEVEL 1 GO TO Trouble

        - saves a copy of CMOS in a file on hard disk or floppy.

CMOSREST.COM  A:MyFile.Sav
IF ERRORLEVEL 1 GO TO Trouble

        - restores CMOS from a file on hard disk or floppy.

CMOSCHK.COM   A:MyFile.Sav
IF ERRORLEVEL 1 GO TO FixIt

         - checks that CMOS has not been meddled with since the
           last CMOSSAVE.  Compares CMOS with a file on hard disk
           or floppy.

Hints on Use
************

Do a CMOSSAVE both to hard disk and to floppy.  The hard disk
copy can be used for quick restores built into your AUTOEXEC.BAT
file.

CMOSCHK.COM  C:\MyCMOS.Sav
IF ERRORLEVEL 1 CMOSREST.COM  C:\MyCMOS.Sav

At that point you must reboot before the restored cmos settings
take effect.  See CHKSAVE.BAT for a realistic way to handle
this.

Sometimes CMOS will be so badly damaged the hard disk parameters
will be corrupt and your hard disk will stop working.  In that
case you will have to revert to using the floppy copy.
