  I've tested a 1542B, Maxtor 338MB, and SVR4 3.0 and 4.0 (early alpha).
  No problem getting them to work together.  I've even recompiled SVR4 4.0
  on that system (heavy disk usage) with nary a problem.  The performance
  is not all that good, at least not what I had expected.  My home system
  with a Seagate ST02 and my own driver run just as fast (ISC 2.0.2).
