- SIMTEL offers five programs that have to do with CMOS reading and/or
- writing. However, not all of them worked properly on my AT clone
- including a Phoenix 80286 ROM BIOS V3.01 (1985 and 1986). If I
- believe my System Board manual (which gives incorrect information in
- at least one case), then I have a MC146818 CMOS.
-
- Anyway, one of the five programs (CMOSER11) wrecked my CMOS contents when
- I just tried to set date and time, ROM2 did not do better. I was lucky
- to have saved the CMOS contents before. (Actually, I was lucky to
- have made two copies, because in my first panic after the message
- "hard disk failure" I inadvertedly saved the faulty CMOS contents
- instead of restoring the good ones.)
-
- Finally, I achieved my original purpose of correcting my original CMOS
- setting (the curious out there who want to know why I did not use a normal
- SETUP to to the job can ask me by e-mail to explain the reason -- a
- lengthy story) with the program SETUP21.
-
- To summarize: saving and restoring worked with CMOS14 (and may have
- worked with other tools), editing my CMOS worked only with SETUP21!!
-
- So, be careful when you try to edit your CMOS contents. Also, if you
- do not completely trust your reflexes in a panic situation, get
- CMOSSAVE out of your way on your emergency diskette.

- CMOS editors).
