- I recently bought an ICD hard drive, and was surprised to find that
- Turtle gave me a fatal error message, even though I had turned off
- CACHEnnn.PRG. After much investigation, I found that the ICD hard 
- disk driver, ICDBOOT.SYS, was the source of this new 
- incompatibility.  It turns out that my ICDBOOT.SYS was 
- pre-configured to allocate blocks for read/write caching. I fired up
- HDUTIL.PRG, and re-configured ICDBOOT.SYS to disable all caching.
- Doing this made Turtle happy. I could then back up my hard drive.
- After that, I re-enabled the ICD caching, and CACHEnnn.PRG.

No need to load HD Util to enable and disable the cache.  Just turn 
it on, and when you want it disabled, hit ESC after ICDBOOT displays 
its version number on boot-up (and before it lists the cache stats).  
(What an ugly sentence, but I hope it got the idea across.)  This 
will temporarily disable the cache.
