System 7.5 Update 2.0: Important Software Updates Read Me

This article describes the Read Me file "Important Software Updates" installed by System 7.5 Update 2.0. This Read Me will only be installed in the folder "Important Software Updates" on PCI-based Power Macintosh computers. The following computers are in the PCI-based Power Macintosh family: Power Macintosh 7200, 7500, 8500, 9500.
This folder contains three software updates that enhance your computer's stability. These updates have been requested by customers using system software version 7.5.3, the version of system software installed on your computer.

This document explains each update. The details below will help you decide if you need to install the updates. Installation instructions are also provided below.

Important: Since these updates are very new, the system software CD or floppy disks that came with your computer do not contain backup copies of these updates. Please follow the instructions at the end of this document to create a backup copy.

Apple Guide Update

This folder contains Apple Guide version 2.0.2, which replaces Apple Guide 2.0 on your computer. Apple Guide 2.0.2 includes the following improvements:

* corrects a problem that causes Apple Guide indexes to be improperly
alphabetized in some languages
* corrects a problem in the way that Apple Guide uses memory (this problem
can cause a decline in system performance and, in some cases, cause the
computer to crash)

To install Apple Guide version 2.0.2, follow these steps:

1. Click the Apple Guide icon in this folder to highlight it.
2. Hold down the Option key and drag the Apple Guide icon to the System
Folder icon. (The System Folder should be closed.)
3. When you see a message asking if you want to put Apple Guide in the
Extensions folder, click OK.
4. A second dialog will appear warning you that an item named "Apple Guide"
already exists in the Extensions folder. Click OK to replace the
existing version.
5. Select Restart from the Special menu.

Drive Setup Update

This folder contains Drive Setup version 1.0.4, which includes the following improvements:

* corrects a problem with some IDE drives
* corrects a problem that could lead to multiple partitions having the same
date and time stamp (this problem is most likely to occur on very fast
systems)

Drive Setup version 1.0.4 does not need to be installed. To use it, double-click the Drive Setup icon in this folder. If you like, you can move Drive Setup out of this folder to a more convenient location on your hard disk (or copy it onto a floppy disk).

Ethernet Compatibility Extension

Important:
The information in this section is for computers connected to a Novell Netware network. If your computer is attached to a Novell Netware network, read the information in this section and install the Ethernet Compatibility extension.

This folder contains the Ethernet Compatibility extension version 1.0.3, which corrects a problem that occurs when you shut down a PCI-based computer that is connected to a Novell Netware network and is running system software version 7.5.3. Without this extension, your computer may crash when you shut down or restart.

To install Ethernet Compatibility version 1.0.3, follow these steps:
Note: After you install this extension, you will notice a two-minute delay in shutting down the computer. After two minutes, the machine will resume the shut down process. To avoid this delay, log out of the Netware network before you shut down or restart your computer.

Making a Backup Copy of These Updates

To make a backup copy of these updates, use a program called Disk Copy.

Before you start, make sure you have a high-density floppy disk. Then follow the steps below. You may want to print these instructions before you begin (open the File menu and choose Print).
To lock the disk:
* Look at the back of the disk.
* Find the square hole with a tab inside it in the corner of the disk.
* Slide the tab toward the edge of the disk so that the square hole is open.

Important: You may encounter errors while running Disk Copy if Virtual Memory is turned on. If Virtual Memory is turned on and you see the message "An error (-620) occurred while reading the disk image" or the message "An error (-74) occurred while copying/verifying the disk," turn Virtual Memory off. Then restart your computer, and begin Disk Copy again.
