available on Apple's FTP servers. Note that this installer incorrectly sets the bundle bit for AppleShare 3.6.2 to "off." While this is not a
major problem, if you run Norton Disk Doctor, you will be alerted to it and should choose to fix it.] NOTE: a few people have claimed that
even with System 7.5.5 and Speed Doubler 1.3.1, the above patch alleviates a problem when copying to a mounted UNIX server where the
server thinks that you don't have write permission.
AppleVision (v1.0.4): if you have a 1710AV monitor and a PCI Mac, you must use v1.0.4 and the Monitors & Sound control panel. 1.0.2
is not compatible with PCI Macs running 7.5.3. If you have a non-PCI Mac, you must use 1.0.2, the Sound control panel, and the Monitors
control panel. To update to version 1.0.4, you must first install 1.0.2, which is available from Apple's ftp sites, before you update to
System 7.5.3.
ASFU Fixer [0/0]: A third party INIT from GDT Technologies which disabled the DMA serial driver originally found on PowerMac and
Quadra AV machines, reverting to the unused non-DMA serial driver in the ROMs of those machines. Apparently, the newer DMA driver
was incompatible with GDT's PowerPrint and the StyleWriter printer. Also needed by a few other products because they were incompatible
with the DMA serial driver and GeoPort architecture. However, applications which used the standard GeoPort architecture of these machines
could encounter problems of their own when using the "patched" driver. The SerialDMA extension (now a part of System 7.5.3) eliminated
the need for this extension.
Assistant Toolbox (v1.3.1): a set of routines for the PowerBook File Assistant which allow file synchronization, better battery management,
and easier mobile computing. It provides support for a persistent RAM disk (normally, you would lose your RAM disk when the computer
is shut down) and deferred printing when a printer is not available (if you are using the LaserWriter driver). It provides better cursor
visibility on passive-matrix displays. It allows AppleTalk to be activated without restarting the computer. It also works with PCI Macs to
enable deferred printing when a printer is not available (again, only if you are using the LaserWriter driver). This extension may conflict
with the LaserWriter Select 310 printer software to block printing. A solution is to turn off background printing in the Chooser. Version 1.2
of Assistant Toolbox is not compatible with Open Transport, and will automatically turn off AppleTalk every time you restart.
At Ease 7.5 Layer Patch: fixes a crash when using At Ease, and the ÒShow DesktopÓ box is unchecked in the General Controls control
panel.
At Ease Startup: forces your Mac to start up in the At Ease launcher instead of the standard Mac Finder (see "At Ease" in the "Control
Panels" chapter).
Audio Volume Extension PM: on 5200, 5300, 6200, and 6300 series Macs, this file replaces/fixes problems with the Internal Modem Sound
extension (actually, a newer version of the IMS extension is incorporated into the Audio Volume extension). Allows modem sounds to be
played through the Mac's own speakers (or external speakers). Also loads a new sound driver which fixes a bug with poor sound quality on
sounds played from the hard drive or CD-ROM's.
AV Serial: I have seen two sources of information on this. One said that this is only needed on AV-card equipped Macs, which does not
include the AV PCI Macs or the Centris/Quadra 660AV/840AV. The other said that it is only needed on the Centris/Quadra 660AV/840AV.
Regardless, it is supposed to have fixed (a) difficulties when printing with the LaserWriter Select 310 printer; (b) a possible system error
when both the serial port and an AppleTalk network connection are being used heavily; and (c) a possible system crash when simultaneously
receiving a fax and transferring files over a network.
