|     Hi All,
|        Here's an odd question.  An office I do some stuff for has two
|     Leading Edge PCs (Model D).  BOth have real-time clocks.  Recently
|     the hard drive on one died completely and I replaced it.  However,
|     this machine was old enough that I used a DOS 3.3 that came with
|     an Epson Equity II+ instead of the DOS 3.1 that was on the Leading
|     Edge's dead hard disk.  Since that time the clock in the Leading
|     Edge whose hard drive died won't keep the time through a cold
|     boot.  I checked the CONFIG.SYS file on the other Leading Edge and
|     that only has the usual files and buffers lines - so there's no
|     clock driver in the config file.  It seems odd that the clock
|     should stop at exactly the same time as the hard disk, so I'm
|     prone to believe that there is a software answer.
| 
|        Assuming the version of DOS I installed is the reason for the
|     clock to stop working, is there an easy way to install an older
|     version of DOS over a newer one without re-formatting?  Can I just
|     delete the COMMAND.COM and the two invisible files and replace
|     them with the equivalent ones from the older DOS?
| 
|        Many thanks .... Adam

You really shouldn't have to change your version of dos.  I changed dos 
versions on my le without a hitch.  You do need to either have 

device=clkdvr.sys

in your config.sys, or a program in your autoexec.bat which reads the
le clock tho.  The standard way is to use CLKDVR.SYS, which is on the
Dos 3.1 distribution disks that came with the leading edges.  There is
also a program that will read the le clock, but it doesn't come with 
the leading edge, and I don't remember where I found it before (and
I've since misplaced that file)  

Anyways, try installing clkdvr.sys in your config.sys & see if it works.
You might also take another look at the config.sys & autoexec.bat on
your other leading edge (with the working clock).  There has to be something
there which handles the clock.

Hope this helps.
