Introduction
This document summarizes the changes made to the United States
Macintosh System Software 6.0.2, since it's release in release in September,
1988.
The United States Macintosh System Software 6.0.3 release is primarily a
maintenance release and a bug fix for the Apple File Exchange. In addition it
provides a hook to support 32 Bit Color QuickDraw, and fixes problems in the
AppleTalk Manager and the Time Manager.
System File
AppleTalk Manager
The ATP bug which caused ATP to send out garbage packets on 68030
machines has been fixed.
Known Bugs
None.
Color QuickDraw
Installation code for 32 Bit Color QuickDraw has been added. During
the boot process for the Macintosh II, and Macintosh IIx the
installation code looks for a file containing 32 Bit Color QuickDraw.
If any errors are encountered during this process, the boot process
will continue normally and no alternate QuickDraw patches will be
installed.
Known Bugs
None.
Disk Driver
A bug in the MFM disk formatting code for the Macintosh IIx was fixed.
This bug caused some MFM formatted disks to be unreadable on IBM
PS/2 systems due to sector 1 not being found.
Known Bugs
None.
Time Manager
The Time Manager has been completely rewritten to fix numerous
bugs.
Known Bugs
None.
Removed Fonts
The New York 18 and 24 point fonts have been removed from the
System File due to space constraints.
No changes in the following
Binary-Decimal Conversion Package, Color Manager, Color Picker
Package, Control Manager, Deferred Task Manager, Desk Manager,
Device Manager, Dialog Manager, Disk Initialization Package, File
Manager, Floating-Point Arithmetic Package, Font Manager,
International Utilities Package, List Manager, Memory Manager, Menu
Manager, Notification Manager, Operating System Event Manager,
Operating System Utilities, Package Manager, Palette Manager, Printing
Manager, QuickDraw, QuickerDraw, Resource Manager, Scrap
Manager, Script Manager, SCSI Manager, Serial Driver, Shutdown
Manager, Slot Manager, Sound Manager, Standard File Package, Start
Manager, System Error Handler, TextEdit, Toolbox Event Manager,
Toolbox Utilities, Transcendental Functions Package, Vertical Retrace
Manager, Window Manager
Responder
Responder has also been modified to recognize all Macintosh
configurations.
Apple File Exchange
o When initializing disks for MS-DOS, all of the root directory is now
zeroed out. This was done as a preventive measure, to clear up
possible problems with trashed directories.
o When an HFS disk is erased, it is now first unmounted from the file
system, even if running under MultiFinder.
o Sound on the AppleCD SC is no longer turned off when starting Apple
File Exchange. This means that when a user is playing music from an
Audio CD with the AppleCD SC driver, starting Apple File Exchange
will not stop the music.
o Also, Apple File Exchange now recognizes external file systems before
looking at data on disk.
o Now Apple File Exchange unmounts a volume's root directory when
is can no longer be displayed. This fixes a bug that caused Apple File
Exchange to display a blank window for an AppleShare volume after
the AppleShare connection died, instead of no recognizing that the
AppleShare volume is no longer present.
o The Text Translator now transfers text characters at a much faster rate,
so that a 64K file will transfer, using the MacintoshPtoPMSDOS text
translator, from SCSI hard disk to SCSI hard disk in about 25 seconds,
instead of the previous several minutes.
o Now able to add enough files to a subdirectory that the subdirectory can
be expanded. This fixes a problem with the MS-DOS routines that
caused a subdirectory to appear trashed because additional blocks for
subdirectories were not being correctly allocated.
o Saving setting several times no longer trashes the Menu bar.
o Removing a directory will no longer corrupt the allocation block table.
This fixes a problem that occurred when deleting all members within a
directory.
o Apple File Exchange will now unmount a disk when it receives an
applicationPevent to eject a "non-ejectable" disk.
o Apple File Exchange will now open "VISA" files that reside in the
system folder.
o A bug that caused Apple File Exchange at startup has been fixed.
o Foreign File Systems now supports the "FFLoad" instruction, which
asks Foreign File Systems to load any resources into memory before
ejecting the system disk.
o Each call to Foreign File Systems is now checked to see if the volume in
question has been disconnected, indicated by either volGoneErr or
nsvErr being returned. If this occurs, the screen for that volume is
blanked at the next opportunity.
o Apple File Exchange now loads all resources necessary for initializing a
disk when the system or application disk is ejected.
o When a VISA file with a foreign file system, 4NFS, in it and the 4NFS
will not initialize (ie. they return an error from the FFInit call), then
the VISA file will be closed. This means that no other resources from
that file will be available.
o If a disk-swap, for some reason, occurs during initialization Apple File
Exchange will now ask for the disk back.
o Now when more than one foreign file system, 4NFS, exists and they
share a nickname, then Save and Restore Settings now works on all
menu combinations.
o Will no longer open a driver that is already open. Also will no longer
close a driver that was already open when Apple File Exchange was
launched.
o Now when unmounting a disk for the MS-DOS file system, the correct
check for a valid volume reference number is made. The lack of this
was causing some disks not to be unmounted, which caused the
capacity of the Foreign File System to handle volumes and subsequent
mountings would then not work.
o One more disk of Foreign File System capacity has been added.
o When opening a local driver, now check the DCE to see if the driver is
honestly is open or not, instead of trusting the unit table entry being
nil.
o Now do not remove disks from the volume list just because they are
ejected. This was causing disks to disappear from windows, as well as
causing subsequent erasures to go awry. Also, when disks are
removed, for example, because of a disconnect, they are always
unmounted.
o Now, when initializing disks, check to make sure that several MS-DOS
disks have been previously ejected.
o When remounting MS-DOS disks, now makes sure to update to the
drive that the disk has been reinserted into. This keeps the "Disk
Switch Alert" from showing up when the disk is moved to a different
drive.
o The proper action now occurs when the "Rename Destination File"
item is chosen from the File menu.
o The bug which caused MS-DOS root directories that were once full, but
now clear to not add new files has been fixed.
The only changes that have been made to the System Software is the
System file, Responder, and the Apple File Exchange.
