A friend of mine purchased a 25 MHz '386 clone recently and has
been having an intermittent problem. Every now and then, with no
discernably pattern, the machine will boot up **very**
slowly (as if it is in 6MHz mode), and then say CMOS checksum error!
When the setup program is run, it appears that the configurations
have all been lost (hard disk, video controller etc) and must be
reset. Everything is fine once this has been done.

I suspect that the battery is flakey but am not sure. Does anyone
have any suggestions? If it is the battery, are there any special 
precautions that must be taken when changing it?

Cheers,

(P.S. - The machine is under warranty but, for some good reasons, it
is not convenient to return it to the store.)
