- 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.
