This file contains instructions for updating DataFrames formatted with previous versions of the Manager software, and describes the operating requirements and known general and specific compatibility information. This file assumes some familiarity with the features of Manager as described in the "Using Manager 4.2" file and in the DataFrame Users Manual.
You can print out this file if you have a printer attached to your Macintosh and selected in the Chooser. Select Print under the File menu.
Manager 4.2 is fully compatible with System 7.0, including Virtual Memory and 32-bit addressing. Balloon Help, Apple Events and the Edition Manager are not supported by Manager 4.2.
SYSTEM REQUIREMENTS
====================
SuperMac products:
All DataFrame models
LaserFrame
Macintosh models:
Any Macintosh with a built-in SCSI port
Apple System Software:
System 6.0.7 or later (The latest version of Apple System Tools is recommended)
While DataFrames run properly under A/UX, the Manager program must be run under the standard Macintosh System.
IMPORTANT: Do NOT initialize your DataFrame with any software other than the DataFrame Manager program from SuperMac. DataFrame performance is already optimized, and doing so will cause your locked utility software to no longer recognize the DataFrame.
Although we have tried to make sure that our drives are compatible with as many other 3rd party products as possible, SuperMac cannot guarantee complete compatibility. Our DataFrame driver conforms to Apple's standards, and we should be compatible with other manufacturers who have also followed Apple's guidelines.
UPDATING TO MANAGER 4.2
========================
A small amount of software known as the "driver" is present on every DataFrame. It is used by the System to communicate with the DataFrame.
To see what driver version is present on a DataFrame, launch Manager 4.2, select the device and choose Get Info from the File menu. DataFrames initialized with Manager version 3.26 will show "Version 3.2" in the Get Info window, while "Version 4.2" indicates a DataFrame running the current software. We recommend that you update all DataFrames that you own to the latest version of the driver.
Special notes about updating:
1. LaserFrame cartridges do not need to be updated. The LaserFrame driver remains unchanged at version 4.1.
2. Users of SuperMac tape drives must replace the DataStream driver 2.02 in the System Folder with TapeDriver 3.0 before upgrading to Manager 4.0 or later. TapeDriver 3.0 is available on the SuperMac BBS and is included with the DiskFit upgrade.
• To update a DataFrame running Manager 4.1 or later, simply launch Manager 4.2, select the DataFrame, and click Update. A dialog appears briefly while the DataFrame driver software is being updated. Restart the Macintosh to use the new driver.
• To update a DataFrame running a driver version EARLIER THAN 4.1, we recommend that you backup and reinitialize the DataFrame. DataFrame models DF20, XP20, XP40, and XP40+40 running driver 3.2 or earlier MUST be reinitialized to update to Manager 4.2. Reinitializing the DataFrame will also insure that the entire media surface is free of defects, and eliminate the problem of defragmentation. Follow these steps:
1. Back up your drive with DiskFit.
2. Boot your Macintosh from a startup diskette containing Manager 4.2.
3. Launch Manager.
4. Select the DataFrame's icon in the Manager window.
5. Click on Initialize. After formatting is complete, choose whether to partition the DataFrame into Drawers, or use one large Standard disk. The directories are then created.
6. Quit to the Finder.
7. Restore your data with DiskFit.
If the driver version was earlier than 4.0, a new icon for your DataFrame will appear after Restarting.
Note: Some older DataFrames DF20, XP20, XP40 and XP40+40 running driver 3.2 or earlier did not have a jumper installed and will display a Sad Mac or play a sad song when they are updated to Manager 4.0 or later. In that case, have a qualified technician open the DataFrame case and install a jumper on the W6 pins in the lower right of the controller card.
SPECIFIC RELEASE NOTES
======================
1. Use only Sony or Seiko-Epson brand, 512 byte-per-sector cartridges with the LaserFrame. The LaserFrame does not work with 1024 byte-per-sector cartridges. Other media brands are NOT recommended.
2. Attempting to mount a DES Protected Drawer on a LaserFrame cartridge with the video display set to 16-bit mode ("Thousands" of colors mode) may cause a system crash. Use the Monitors Control Panel to set the number of colors to a different value.
3. System 6.0.5 has a problem with memory space that may cause a Finder damaged message when running from a DataFrame with driver 4.0.x. The driver installed by Manager 4.1 and later allocate more system memory to prevent this problem.
4. The initialization routine in Manager 4.0.x for older DataFrame 20-60 MB models using separate OMTI controller boards (with vents on top) may miss some 'marginal' data sectors. Manager 4.1 and later correct this problem. Users of these DataFrames are strongly encouraged to Test or, better, backup and Initialize their drive to be sure all marginal sectors are mapped out.
5. Manager 4.0.x would damage A/UX partition information when the Drawers box was accessed. This does not occur with Manager 4.1 and later.
MANAGER HINTS
==============
Below is a list of release notes that will help to make your use of the new Manager as trouble-free as possible.
Before starting your Mac, make sure that you have allowed enough time for your drive to spin up completely. Thirty (30) seconds should be long enough to ensure that the drive is ready. If the drive is not ready, it may not start up properly.
If your password is not working, the first thing to do is check the Caps Lock key. If you forget the password of a Drawer, you will not be able to access or remove it. SuperMac will not be able to recover your data, and cannot assume responsibility for lost passwords. In this case, the only way to get a clean start is to reinitialize.
All 30 MB and larger DataFrames manufactured since 3/89 automatically park their read/write heads when they are turned off. To park the older 20, 30 and 40 megabyte DataFrames, hold down the Option key when selecting Shut Down from the Special menu in the Finder. The Park command in Manager can also be used to park the heads of older DataFrames.
Many DataFrame drives change ID automatically through software. Manager 4.0 and later allow SCSI IDs to be changed even when a drive is in use. Please note that for some mechanisms, the new ID does not take effect until the DataFrame has been turned off and then back on again. Manager informs you of this in the change ID window where necessary.
When the test is run and defects are detected, Manager will map out the bad areas (sectors) it detects and also attempt to move any data that may be stored in the bad sector. There is no way of knowing what file is on a bad sector of the drive, and Manager will move any data that can be successfully read.
When using the Startup Device cdev with multiple Drawers, please note that it only saves the SCSI ID of the entire DataFrame. If you close the cdev and reopen it, you will note that all the Drawers on the drive you selected are highlighted - this is normal since the SCSI ID is being saved, not the specific Drawer. To designate a specific Drawer to be the Startup Drawer, use the Startup Drawer feature under the Drawers menu in Manager.
When you change the name of a Drawer which is protected by a password or DES Protection, the password dialog will still refer to the old name. In order to completely change the name, run Manager and open the Drawers dialog with the Drawer mounted. The Macintosh's volume information and the partition list entry will then be made to match.
The Manager CDEV cannot unmount volumes in the Finder. Volumes can always be unmounted by dragging them to the trash. The Manager CDEV will not see drives when there is no driver loaded (e.g. if you boot to the Desktop and then turn on the drive). In this case, Manager should be used to Start the drive.
If "Open Automatically" is deliberately turned off on a DataFrame that has been formatted as Standard, it will not boot. The only way to mount it is with Manager or the CDEV.
When creating Drawers, bear in mind that the Finder has memory limitations and may run into problems if you are trying to have too many volumes mounted at one time. Having 5 or fewer Drawers mounted simultaneously should not cause memory problems to occur. The "Max Number of Open Files" parameter in the boot blocks defaults to 10; this represents the total of both mounted volumes and open files at one time. Power users may increase this value (no higher than 25!) using FEdit or similar utility if it is desired to have more open volumes. If you are running under MultiFinder and have the memory to spare, you can allocate more memory (e.g. 256K) to the Finder (160K is the default setting).
When using a grayscale monitor, be sure that you have set the Monitors cdev to Grays (not Colors) mode. This will cause the partition wheel to use patterns to represent the various Drawers. If your grayscale monitor is set to color mode, the partitions on the wheel may be very hard to distinguish.
SPECIFIC PRODUCT COMPATIBILITY
===============================
• Apple File Exchange will not work unless all Drawers are mounted. This is a bug in AFE.
• The SCSI Tools cdev and the MountEm™ FKEY will not be able to mount DataFrames that use the 4.x driver. DataFrames require a more sophisticated mounting procedure due to the various protection methods. If you need to mount drives or Drawers, use Manager or the Manager CDEV. (SCSI Tools version 1.0 will cause some SuperMac and Apple drives to hang just by opening it.)
• Older ROM versions for the Radius Two Page Display for the Macintosh SE exhibit an anomaly with password dialogs where the characters for the password appear a few inches to the right of the password dialog. This is due to the fact that the Radius board makes patches to QuickDraw that cause centering to occur differently on the Two Page Display Screen. All the keys work correctly and the password is recognized when entered.
• Prodigy 4 Mac Plus users note: You must use emulation mode to change ID and to reinitialize the DataFrame. This is due to Prodigy 4 patches to the SCSI Manager code.
