[comp.sys.atari.st] ICD Driver Bug

david@bdt.UUCP (David Beckemeyer) (02/20/88)

BEWARE!
The ICD Hard Disk Driver has a serious problem.  It trashes the
A6 register, which is supposed to be non-volatile.

The error first showed up when we discovered that the Beckemeyer
Development Hard Disk Accelerator used with the ICD drivers causes a
system crash.  This error can also affect any program that uses the
"hard-disk" I/O vector at $476 (ram disks, cachers, networks, etc).

The version of ICD Drivers that has this bug is 1.6.  Until they
fix it, please DO NOT USE caching, RAM disks, or any other program
that may use the disk I/O vectors.   The Supra, Astra, Atari, and BMS
hard disk drivers do not have this bug, and all will probably work
with the ICD host adapter.  ICD users: I recommend using one of these
other driver programs until ICD fixes their drivers.
