Apple System 7 Pro - Manual (Page 16)

- the general load conditions of your network
- the type of Macintosh being used as a server
- additional purposes for which the server is being used
For best results, you should set up the upgrade server on a Macintosh that is
not used heavily as a general-purpose server.
Simultaneous user installations
It's recommended that users do not attempt to access the upgrade server in
large numbers simultaneously. While the System 7 Pro Installer is a multi­
user program that supports simultaneous installations, the intensive two-way
traffic of installing and verifying software on multiple hard disks can
significantly degrade network performance.
Software compatibility
The System 7 Pro MultiPack contains a Compatibility Checker program to help
you assess the compatibility of the software your workgroup uses. You
probably used this when upgrading your own Macintosh or PowerBook in the
first part of this handbook.
The Compatibility Checker is located
- on the Before You Install disk in the System 7 Pro installation disks
- in the Before You Install folder on the System 7 Pro CD-ROM
Use the Compatibility Checker to determine whether you'll need to update any
programs for use with System 7 Pro.
INITs and CDEVs in System 7
Many users have special files in their System Folders called INITs (startup
documents or initialization files) and CDEVs (control panel devices). These
files support application programs, drive peripheral devices, or add
functionality to the Macintosh or PowerBook. Because these programs are often
loaded as part of the startup process, a compatibility problem could prevent
the computer from starting up.
!! IMPORTANT: Compatibility is most critical when a program is installed in
the System Folder. If any INITs or CDEVs installed on your Macintosh or
PowerBook are not recognized by the compatibility tools you received with the
new software, you should remove them from your System Folder before
installing System 7 Pro. ! !
New names for INITs and CDEVs
Beginning with System 7, Macintosh INITs were renamed system extensions, and
CDEVs were renamed control panels.
Application programs and System 7
Most currently shipping versions of application programs are compatible with
performance factors, including
