IMPORTANT NEW INFORMATION

The following issues are not covered in the Read Me file.
Please read this information before installing Mac OS 7.6.1
Update on your computer.

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 in the same
locations as this update.

68040 COMPUTERS AND CLOSED CAPTION FEATURE IN APPLE VIDEO
PLAYER
Apple Video Player's Closed Caption option will cause a hang
on a 68040 computer with the Apple TV Tuner card 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 PLAYER 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 AND 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'S 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'S 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.

POWER MACINTOSH 5500 and 6500 SCREEN REFRESH PROBLEM WITH
MPEG MOVIES
Windows of MPEG movies on Power Macintosh 5500 computers may
exhibit white areas obscuring the movie in the window.
Removing the ATI MPEG extension from the Extensions folder,
or manipulating the movie window will work around the
problem.
