Mac OS 7.6.1 Update for PowerBook 3400 
Overview and Installation


What's included in the Mac OS 7.6.1 Update?

This document contains information on Mac OS 7.6.1 Update
for all Power Macintosh and Mac OS Compatible computers,
however this installer will only install on the PowerBook
3400.

After you install the Mac OS 7.6.1 Update, you should notice
improved stability, as well as the following fixes and
enhancements:

* Nearly all Type 11 errors eliminated 
Type 11 errors force you to restart the computer without
saving your work. Most of these errors are now properly
classified as Type 1 or Type 2 errors, which cause the
active application to quit, but do not force you to restart
the computer. Type 11 errors occur while using "native"
applications used by computers with PowerPC processors.

IMPORTANT When you get an error that forces a program to
quit, you should still save your work in other open programs
and restart the computer. 

* Type 112 errors eliminated
Type 112 errors, which occurred when using some multimedia
applications, have been eliminated. 

* CFM-68K Runtime Enabler included for computers with 68030
and 68040 processors
Computers with 68030 and 68040 processors can now use
programs that require the CFM-68K Runtime Enabler. The
CFM-68K Runtime Enabler is a system extension which allows
application programs to share code resources. Because of a
problem with this extension, it was not included with Mac OS
7.6. This problem has been fixed. 

Apple products that use the CFM-68K Runtime Enabler include
OpenDoc, the LaserWriter 8.4 driver, Apple Telecom software
3.0 and later, and the Apple Media Tool. Applications from
other companies that require the CFM-68K Runtime Enabler
include America Online 3.0 and Internet Explorer 3.0. (If
you continue to experience problems with non-Apple programs
that use the CFM-68K Runtime Enabler, contact the
manufacturer.) 

* Improved compatibility with serial devices when using
Performa 5400 and 6400 and PowerBook 3400 computers
Equipment connected to the serial port now communicates
correctly with these computers. (Previously, some devices
using the serial port were not recognized by these computers
if the devices were connected when the computer started up.)


* Infrared problems fixed on PowerBook 1400 and 3400
computers
The computer no longer freezes if the infrared window is
blocked when the computer is starting up or transferring
files. 

* Improved reliability when using large QuickTime files, or
using QuickTime in low-memory situations
Application programs that use QuickTime files work more
reliably when working with large files and when using
QuickTime files in low-memory situations. 

* Printing improved for Performa and Power Macintosh 5400
and 6400 series computers using non-Apple printers over
LocalTalk networks
Performa and Power Macintosh 5400 and 6400 computers now
print at an acceptable speed on non-Apple printers over a
LocalTalk network. (Previously, printing was very slow.) 

* Video applications recognize that MPEG is installed
Video applications, including the Apple Video Player, now
correctly recognize when MPEG software or hardware is
installed. 

* Storage PC Cards no longer require a utility program to
appear on the desktop
PC Cards used for storage now appear on the desktop when
inserted. A mounting utility program is no longer required.

* Only two low-battery messages displayed on PowerBooks
before computer shuts itself down
Only two low-battery messages are displayed, instead of
three, before the computer shuts itself down. The first
message appears approximately two to four minutes before
shutdown. The second occurs approximately ten seconds before
shutdown. 

* PowerBook 1400 computers now wake from sleep faster
When you wake the computer, there is less of a delay before
the screen appears. 

* Contrast and brightness controls work as expected on
PowerBook 1400 computers
The screen will get brighter or show more contrast when the
plus (+) controls are pressed. Previously, the functionality
of the plus (+) and minus (-) controls were reversed on
PowerBook 1400 computers.

* On the PowerBook 3400, the CD-ROM drive works correctly if
inserted when the computer is on
The removable CD-ROM drive now appears correctly on the
desktop if it is inserted in the expansion bay while the
computer is on. 

* New version of Apple System Profiler 
IDE-based CD-ROM drives, such as the built-in CD-ROM drive
for the PowerBook 1400, are now listed in the Apple System
Profiler window. 

* New version of AppleVision software
A new version of AppleVision software improves reliability
on computers that currently use AppleVision monitors.

* Graphics acceleration software works correctly with a
universal System Folder
Graphics acceleration software now works correctly when used
with a universal System Folder. Additionally, the Graphics
Accelerator extension and the Graphics Accelerator 2
extension have been merged into the ATI Graphics extension. 

* New version of Apple Video Player
All computers can use the AppleScript scripting language to
automate tasks in Apple Video Player. 

* Settings in Energy Saver control panel are saved properly
Changes made to automatic startup and shutdown settings are
now saved.

* Large files copied between IDE hard disks sometimes
crashed the system
Files over 1 MB can now be copied between two IDE hard disks
without causing a system crash. 

* Better performance when using video-capture expansion
cards and ATI accelerators
Video capture is faster on computers when using
video-capture PCI expansion cards with ATI graphics
accelerators. 

Besides the bug fixes provided by Mac OS 7.6.1 Update,
several of the bug fixes and features that have been
previously released as extensions are now part of the OS.
You may notice that these extensions have been removed from
the Extensions folder. After installing the Mac OS 7.6.1
Update, you will no longer need these extensions in your
Extensions folder.

Known problems with Mac OS 7.6.1

Open Transport 1.1.2 and PowerBook 3400
Open Transport 1.1.2 and the PowerBook 3400 are not
compatible unless you follow these instructions. Open
Transport 1.1.2 was released to address issues with very
specific network configurations of some customers, and is
not required for most Open Transport users. If you require
version 1.1.2 of Open Transport for your network
configuration, first install Open Transport 1.1.2, and then
immediately install the Mac OS 7.6.1 Update for PowerBook
3400. This will overwrite resources which otherwise could
cause crashes when switching between Infrared and LocalTalk.

PowerBook 1400 and Newer Technology Ethernet Card
A PowerBook 1400 used with the Newer Technology Ethernet
card requires Ethernet driver version 1.5 or later from
Newer Technology. Drivers older than version 1.5 may cause
crashes. Visit Newer Technology's web site for the latest
version: http://newertech.com/software.html, or call their
Tech Support at 1-800-678-3726.

Infrared Control Panel Produces Incorrect Error
If the Infrared control panel is selected on a computer that
does not have infrared capability, an error -192 message is
displayed. The error should state that Infrared is not
supported on this computer.

Printing Speed Improvements
Improved print speed is present for some computers using
third party printers over LocalTalk networks, however, Power
Macintosh 5400 and 6400 computers with processor speeds less
than 200 MHz without an L2 cache still exhibit slow
printing. Apple is working on a solution to this problem,
and will post a solution as soon possible online in the same
locations as this update.

68040Computers and Closed Caption Feature in Apple Video
Player
Apple Video Player's Closed Caption option will cause a hang
on a 68040 computers with the Apple TV Tuner installed.
Reinstalling the Apple Video Player (version 1.4) from the
Mac OS 7.6 CD will remedy the problem. To reinstall, launch
"Install System Software" in the Mac OS 7.6 folder within
the Software Installers folder on the Mac OS 7.6 CD.  Choose
"Custom Install" from the pop-up, then click on the triangle
next to the item "Multimedia" to expand it. Select "Apple
Video Player 1.4" and click "Install." When asked if the
"Newer" or "Older" file should be used, select "Older."

Apple Video Player & Mac OS 7.6.1 Incompatible with
QuickTime MPEG Card
Apple Video Player will not properly recognize a QuickTime
MPEG Card when run under Mac OS 7.6 or Mac OS 7.6.1. With
Mac OS 7.6.1 the QuickTime MPEG extension can be used to
view MPEG files using software decompression with Apple
Video Player. 

Apple Video Plaer 1.6 is not Installed on PowerBook 3400
If you need to use this application program, it can be
downloaded from http://www.info.apple.com.

Power Macintosh 7100/80AV & Apple Video Player Sound
Problems
If the sound is muted and the slider doesn't work in Apple
Video Player on a 7100/80AV, open Apple Video Player and
click on the mute button to activate it. Quitting and
relaunching the Apple Video Player should then remedy the
problem.

Mac OS 7.6.1 and AppleVision 1710: Missing Colorsync Profile
If you try to import the "AppleVision 1710-9300" ColorSync
profile, and the error
 "Could not complete your request because a ColorSync error
has occurred."  appears, install AppleVision 1.5.1 to
eliminate the problem.

Extensions Manager Mac OS 7.6.1 Sets Omit File Needed to
Print
Selecting "Mac OS 7.6.1 Base" and "Mac OS 7.6.1 All" in
Extensions Manager, mistakenly turns off "Printing Lib" and
printing is disabled. Manually turning on "Printing Lib"
within Extensions Manager after choosing one of these sets
will allow printing.

Extensions Manager Mac OS 7.6.1 Sets Omit Monitors Control
Panel
Selecting "Mac OS 7.6.1 Base" and "Mac OS 7.6.1 All" in
Extensions Manager, mistakenly turns off "Monitors" control
panel. Manually turning on "Monitors" within Extensions
Manager after choosing one of these sets will allow access
to this control panel.

Internal Speaker on Power Macintosh 5500 and 6500 Remain
Muted
If external speakers are connected to a Power Macintosh 5500
or 6500 when the computer starts up and are then
disconnected, the internal speakers remains muted. Restart
the computer after disconnecting the external speakers and
the internal speaker will work normally.

VM is not Turned on for 68030 & 68040 Computers with More
Than 16 MB of RAM
68030- and 68040-based Macintosh computers with more than 16
MB of physical memory do not have Virtual Memory turned on
after installing Mac OS 7.6.1 Update.

Known problems with Mac OS 7.6 not fixed with this update

* Connectix Speed Doubler disabled when Mac OS 7.6.1 is
installed
There is a problem using Speed Doubler versions 1.3.1 and
earlier and version 2.0 with Mac OS 7.6. If you use one of
these Speed Doubler versions, it will be disabled after you
install Mac OS 7.6.1 Update. Connectix is aware of this
problem and is providing a free update. For more
information, see the Connectix Web site at
http://www.connectix.com, or call 800-839-3632.

* Versions of several Apple software products compatible
with computers with 68030 and 68040 processors that require
the CFM-68K Runtime Enabler not included with Mac OS 7.6
Because of a problem with the CFM-68K Runtime Enabler, the
extension and compatible versions of several Apple software
products (such as OpenDoc, the LaserWriter 8.4 driver, Apple
Telecom software 3.0 and later, and the Apple Media Tool)
were not included with Mac OS 7.6. The CFM-68K Runtime
Enabler problem has been fixed and computers with 68030 and
68040 processors can now use programs that require this
extension. The latest version of this software is available
on "Apple SW Updates" on the Internet
(http://www.info.apple.com), America Online (keyword:
AppleComputer), and CompuServe (GO APLSUP). To get a list of
authorized mirror sites on the Internet, access the
following URL:
http://support.info.apple.com/ftp/mirrors.html

* LaserWriter 8.3.4 results in an error message when you
print to a file and then drag the resulting file to a
desktop printer
If you use the LaserWriter 8.3.4 driver to print to a file
and then drag the resulting file to a desktop printer, you
get a message stating that the print library is missing. To
work around this problem, update your LaserWriter software
to LaserWriter 8.4.1. This software is available on "Apple
SW Updates" on the Internet (http://www.info.apple.com),
America Online (keyword: AppleComputer), and CompuServe (GO
APLSUP). To get a list of authorized mirror sites on the
Internet, access the following URL:
http://support.info.apple.com/ftp/mirrors.html

* After you install Mac OS 7.6.1 Update, the easy install
option no longer works for reinstalling Mac OS 7.6
Once you have installed Mac OS 7.6.1 Update, you can no
longer use the easy install option for reinstalling Mac OS
7.6 (installers cannot update over newer versions of
software). You must use the clean install option to
reinstall Mac OS 7.6. Specific components can be installed
using the custom install option.

* Notes on Custom Installs
If you perform a custom install of a component from your Mac
OS 7.6 CD (or floppy) and already have system 7.6.1 running
on your system, you may notice the following warning dialog:
 "The file <name of the component>  already on  <name of
your hard drive>  is newer than what you are about to
install. Click Newer to keep the Newer file, Older to
replace that file, or Cancel to stop installation." You
should pick Newer.

IMPORTANT After the Mac OS 7.6 install finishes installing
the selected components, you should then reinstall the Mac
OS 7.6.1 Update to ensure that the components you just
installed are up-to-date.

* Installing QuickDraw GX for use with a non-Apple printer
If you want to use QuickDraw GX with a non-Apple printer,
you need to obtain a QuickDraw GX printer driver or remove
QuickDraw GX. If QuickDraw GX is installed, you will not be
able to use your non-Apple printer without a GX driver.
Contact your printer vendor for details. (Turning off
QuickDraw(TM) GX in the Extensions Manager will solve this
problem.) 

*	Using the QuickDraw GX Installer when Adobe Acrobat is
installed
If you use the QuickDraw GX Installer to either install or
remove QuickDraw GX and your computer has Adobe Acrobat
installed, Acrobat will display a message about missing
fonts each time the computer is restarted. Reinstall or turn
off Acrobat to stop the warning message. (Turning off
QuickDraw(TM) GX in the Extensions Manager will not solve
the problem.) 

* Video Startup extension and Apple Video Player improperly
installed by Mac OS 7.6
Mac OS 7.6 improperly installs the Video Startup extension
and the Apple Video Player application on Macintosh TV. You
should throw the Apple Video Player application and the
Video Startup extension in the trash. If these components
are present, the Mac OS 7.6.1 Update will update them to
newer versions which still do not work on Macintosh TV.

* 3D images cannot be viewed with OpenDoc 3DMF Viewer 1.0.1
with QuickDraw 3D 1.5 or 1.5.1 installed
If QuickDraw 3D 1.5 or 1.5.1 is installed, a message about
insufficient memory appears when attempting to place a 3D
image in an OpenDoc document. Increasing the viewer's memory
size with the Get Info command in the File menu does not
solve the problem. To use the 3DMF Viewer, install an
earlier version of QuickDraw 3D.

* Macintosh customers with  the DayStar Digital 040 cards
will need to do the following:
If you use the DayStar Digital 040 card, you will have to
first remove the card, then install Mac OS 7.6.1 Update, and
then reinstall the DayStar Digital 040 card
 
* Two system folders when no desktop printer is selected
If you notice two active system folders on your hard drive,
create a desktop printer to work around this problem.  To
create a desktop printer select the Chooser in the Apple (*)
Menu, select any printer, and then press the Create button.

7.6.1 Update.


Updating a universal System Folder

A universal System Folder can be used to start up any
computer that can use Mac OS 7.6.

Only some users need a universal System Folder. You might
want to create a universal System Folder if you
* start up different computer models using removable media
  or an external startup disk
* want to simplify support of multiple users by giving all
  users the same System Folder

The universal System Folder will not contain
* the Password Security control panel
* ATI 3D Accelerator, ATI MPEG Accelerator, ATI YUV
  Accelerator, and ATI 6500 Graphics Extension
* ATI Graphics Accelerator 1.2.2 (ATI Graphics Accelerator
  1.1.4 is installed in the universal System Folder)
* the Infrared control panel, IrDALib, and IRLanScannerPPC
* the CDStrip control strip module
* the TV/FM 1.5.3

If you are responsible for only one computer, you shouldn't
need to create a universal System Folder.

1. Start with a universal System Folder created by the
Install Mac OS program (available on the CD or floppy disks
that came with Mac OS 7.6).

2. Update your universal System Folder by installing Mac OS
7.6.1 Update.
