OS/2 2.11/Warp fix for possible RZ1000/CMD640x PCI IDE data problem

Version.1.1    

Please follow directions in the README.TXT file to install this fix.

Disable Read-ahead mode for the RZ1000 and CMD640x PCI IDE chips in the
OS/2 IBM1S506.ADD and CMD640X.ADD device drivers.  These are generic
device drivers which fix all the above releases and are compatible
with systems that DO NOT use the RZ1000 or CMD640x chips.

The new IBM1S506 device driver detects the RZ1000 and disables read-ahead
for both RZ1000 IDE channels.  The IBM1S506 device driver also detects the
CMD640x chip and disables read-ahead for the primary IDE channel.

The new CMD640X device driver detects the CMD640 chip and disables
read-ahead mode for both CANT IDE channels.
