- Then it's not the problem I was having. Sorry, then I don't know what it is.

- Well, on my 486, the CMOS RAM setup allows to to set "memory timing" to
- "slow" or "fast", and a bunch of other stuff. WHen I was trying to get
- "0.0newer" to run, I set all the CMOS RAM setups to the slowest, "most
- conservative" values, and created a problem for myself with the Adaptec... ;-}
-
- But again, it sounds like your problem is different.
