Name:         Power Macintosh 4400 Update

Version:      1.0

Released:     August 20, 1998

Requires:
Mac OS 8.1 and any of the following computers: Power Macintosh 4400,
Power Macintosh 7220, Motorola StarMax series, and the UMAX Aegis
computer (sold only in Asia). This will not install on any other
machines or any other version of Mac OS.

Description:
The Power Macintosh 4400 Update contains two patches for Mac OS 8.1. The
first patch corrects a memory corruption problem caused by Mac OS
Extended (HFS+) that results in systems that will not boot after being
upgraded to Mac OS 8.1.  The symptom is a hang during startup (for
example, when the Happy Mac icon appears, or when the "Welcome to Mac
OS" screen appears, or while the extensions are loading).  This problem
can occur even if there are no Mac OS Extended volumes in use. The
second patch corrects an obscure problem with the ATA Manager. The
symptom is what appears to be a hung system -- the mouse pointer will
move but the system does not respond (it is in an infinite loop).  If
you are using a PC Compatibility Card, you will not be able to switch
back to the Mac OS environment. This update also corrects this problem.
This update modifies the system file to correct the Mac OS Extended
problem and installs the "4400 ATA INIT" extension to correct the ATA
Manager problem.  When the update is installed, the system version in
the "About This Computer" window will be listed as "Mac OS 8.1" and
"System Enabler 4400 Update". Note: an enabler is not installed. This
information is listed so that users can determine if the update has been
installed.
