[comp.sys.ibm.pc.hardware] EMERGENCY! Friend uses CMOS___, manages to clobber system

mholtz@sactoh0.sac.ca.us (Mark A. Holtz) (04/04/91)

Boy, do I wish this was only an April Fool's joke.

I lent to a friend PC Magazine's "PC Power Tools" and the diskettes
with that book. This afternoon, I got one of those "URGENT: Call me
immediately, or else . . . " messages on my answering machine.
It turns out that he tried out some of the programs on the disk
without first consulting the book, and managed to rum CMOSPUT,
which clobbered his setup information. Now, when he boots up, he
gets "Wrong Version Number. Bad or Missing COMMAND.COM" (wording
not exact). No, he did not have backups. 

How do I get my friend going again? His system is a AT-286 clone
with AMI Bios and 640K of memory. He uses a 40MB hard drive,
partitioned into 2 - 20MB portions. The Video Card is a Hercules
clone.

This sounds like the same result he would get when the CMOS battery dies.
That shouldn't be a fatal event.  On the HP Vectras I work on I would just
run the SETUP program that comes with the hardware to redefine all the CMOS
parameters.

Your friend simply has to get into SETUP and make the correct settings. I don't
know how old his AMI BIOS is but the later 386 ones require (to the best of
my knowledge) hitting the Delete key while the system is booting up.  His may
be different, consult the manual.  The values that require changing are:
drive type, memory configuration, display, floppy drive configurations.  There
may be others but that should get him up & running.

Good luck.

Tell your friend to download a program called CMOS_RAM from his favorite
BBS.  When run the first time, it stores your CMOS battery-backed up
data to floppy.  Then, if the CMOS battery craps out, or something blows 
up the CMOS backup data, you run the program and it automatically restores
what was in CMOS memory.

You first format a floppy disk with the /S option.  This puts the system on
the disk.  Then copy CMOS_RAM.EXE to this floppy.  Run the program from the
floppy and answer the menu questions.  Put the disk away with your hard disk
backups (you DO backup your hard disk, don't you?) Then if the computer loses
it's CMOS brains, you boot directly from the floppy by putting it in the
drive and turning on the power.  (Since the CMOS data is gone, the computer
can't find the hard disk and therefore can't boot so you have to do it from
the floppy.)

CMOS_RAM was written by Thomas Mosteller.  Last known address was 1872
Rampart Lane, Lansdale, PA 19466.  His shareware fee is $5.00, well worth
the hassle of looking up the HD parameters, etc to rebuild SETUP.
