System 7.0.1 Change Overview
October 1991
CDEVs/Extensions:
Memory:
RAM Disk support on Quadra and PowerBook machines. Support for RAM Disk on
Macintosh Portable has been moved from the Portable CDEV to Memory. Minor
internal changes have been made to all of the “panels” inside memory.
Specifically, the VM and RAM Cache “panels” have been updated to work correctly
with the new RAM disk and to work with the existing RAM disk on Macintosh
portables. The previous version of the Memory control panel would let users
reduce the size of the VM backing store (by reducing VM). This change would
take effect before re-boot. This has been corrected under 7.0.1 to not occur
until reboot.
Portable:
The screen brightness and contrast sliders previously found in Portable have
been removed. The PowerBook family has hardware controls on the front of the
machine to control contrast and brightness. For the Classic family, Macintosh
Portable, and PowerBook 100, a dedicated CDEV called “Brightness” provides
users of those machines with control of the overall screen brightness. RAM
disk controls for Macintosh Portable previously found in “Portable” have moved
to “Memory.”
Portable supports internal modems in PowerBook 140 and 170 as well as in
Macintosh Portable.
Brightness:
The brightness CDEV supports Macintosh Portable, Classic, Classic II, and
PowerBook 100 computers. The CDEV is a simple slider that controls overall
screen brightness.
Network:
Minimal changes to support on-board Sonic Ethernet for the Quadra family have
been made to Network.
Battery:
Battery has been updated to work with the PowerBook family—it also sports a new
look. Battery now provides users with a button to put the computer to sleep
immediately.
Caps Lock:
The Caps lock indicator panel places a visual indicator of the state of the
Caps Lock key on the right end of the menu bar. Only available on PowerBooks.
File Sharing Extension:
An internal 4k file sharing buffer has been increased to 5k in size. With the
increased performance of the Quadra family built-in Ethernet, a slightly larger
buffer increased the file sharing throughput by 2 times on those computers.
Cache Switch:
A CDEV for the Quadra machines that enables the user to disable or enable the
68040 caches was added to the system. The CDEV simply sets a PRAM byte and the
System does all the work at the next boot.
A/ROSE:
Includes general 68040 compatibility changes.
DAL:
Includes general 68040 compatibility changes.
HD SC Setup:
Minor changes to support new hardware and to change a format-time mode select
were made.
System File
OS:
Keyboard patch wakes up sleeping Putter (Macintosh Classic) keyboards.
Support for the 53C96 SCSI chip found in the Quadras and PowerBooks 140 and
170. A boot time linked patch was added to wait for all SCSI drives connected
at that time of the previous boot to spin up before the boot continues.
Quadra, PowerBook 140 and 170 only.
Minor LocalTalk changes for 68040 compatibility.
Minor changes to Gestalt ‘lram’, ‘ram ‘, and ‘kbd ‘ selectors for RAM
disk/PowerBook keyboard support.
Updated _hwPriv CPU cache management and dispatch routines.
Updated keyboard maps for “Key Caps” (PowerBook keyboard).
Support for the new PowerBook 140, 170 power manager
Startup code inhibits 68040 cache depending on setting of Cache Switch CDEV.
Bit mapped system fonts were marked unpurgeable in System 7.0. These have now
been marked purgeable under 7.0.1.
ToolBox:
SANE (Standard Apple Numerics Environment) performance has been improved via
backpatching. The new SANE is functional on all machines with a IIci class
universal ROM and a Floating Point Unit. Occasionally noticeable in
applications that use SANE on machines with a FPU.
The Disk Initialization Package will now create an MFS disk when the size of
the volume is exactly 800 blocks (400k), instead of doing so on sizes less than
or equal to 800 blocks. This is to prevent RAM disks that are smaller than 800
blocks from being formatted as MFS volumes. It is impossible to create a RAM
disk with exactly 800 blocks.
The Notification Manager has been changed to call IdleUpdate when NMInstall is
called (on portables) to wake the system up when a notification is about to be
posted.
Support for enabling powerdown messages on Quadra 900 and RAM disk “has files
on it and will be erased if you shut down” warning code have been added to the
Shutdown Manager. Also, all open video drivers are closed before the power is
killed at _Shutdown.
Support for Quadra and PowerBook sound hardware and internal sound input source
selection has been added to the Sound Manager.
The backlight driver has been upgraded to work with the PowerBook family.
SetHandleSize was fixed for all 32-bit memory managers.
General:
Various strings and dialogs required in the support of the new CPUs have been
added to the system.
Several minor changes that reduce the overall size of the run time system heap
were made to compensate for the memory required by the new CPU support.
The Installer script file has been substantially revised to address the needs
of the new CPUs.
