- It probably won't run as fast. I ran into this situation when I was
- benchmarking systems for my new machine. I got two different results on
- the same basic machine at different stores. When I finally got my system home
- and played around with the BIOS settings I was able to get the same results.
- The machine ran faster with Hidden Refresh enabled. Incidently, I just added
- another Meg of Ram to my machine (4 qty 256k x 9 SIMMS) and ran into the
- telltale Parity error problems. I decided to risk turning Parity Checking off
- in the setup. I've been running it like this ever since. Time will tell if
- it will cause an ugly error.
