SUMMARY
=======

If SMARTDRV.SYS is loaded high on a system with a Micropolis 330 MB hard disk
model #1578-15 with Adaptec Controller model #1542-B, and it is partitioned into
a single drive, the system will hang.

Loading SMARTDRV.SYS low before loading anything high solves the problem.

MORE INFORMATION
================

The disk transfers to the upper memory block (UMB) are not being put at the
right addresses because the controller is not mapping addresses correctly. The
only workaround available is to load SMARTDRV.SYS low (in conventional memory).
