- NREFRESH was copied from Micro C #35 p.30. The original was written
- by Larry Fogg. Micro C, by the way is one of the better Micro Magazines
- available. Micro C along with Programmer's Journal are the only PC
- magazines to which I subscribe.

- NREFRESH.COM is a small program which changes the PC's DMA
- refresh rate. The DMA controller issues refreshes less often and
- therefore more time is devoted to the execution of programs. It really
- works. My PPC with a V20 chip normally shows an old Norton SI of
- 1.7. With the speedup it shows either 1.8 or 1.9. Overall, the
- improvement is around 6%. Pretty good for a 14 byte program. I have
- been running for several days now without a crash. If you have a
- strange machine, you may not get as good results or your memory may
- die on you, but this seems to be about 100% workable on my Portable.

- The only bad thing I can say is that there is occasional snow on the
- CGA monitor. I suspect that IBM increased the refresh rate on
- purpose to slow the PC down a few percent to get rid of the CGA snow.
