This article describes how to make the switch to Open Transport and install OT/PPP for the first time.
DISCUSSION
OT/PPP requires that you be running System 7.5.3 or later, Open Transport 1.1.1 or later, and OT/PPP 1.0 or later.
Step 1
If you are using a Performa or Power Macintosh 6200, 6300, 5200, or 5300 series computer (except for the 5260, 6320, or 6360), you should obtain a copy of the 5xxx/6xxx Tester. This will check your computer for the presence of an issue with your level-2 cache which prevents Open Transport from installing correctly. If the tester indicates that a cache problem exists, then you must get a repair performed on your computer; this repair will be covered by the Repair Extension Program. Note that the REA tester may also fail the computer for non-cache issues: in this case, OT can be installed.
If you have Internet access, you can download the 5xxx/6xxx Tester from the Apple Software Updates Web site at http://www.apple.com/swupdates .
Step 2
If you are not already running System 7.5.3 or later, then you must upgrade with System 7.5 Update 2.0. You can download System 7.5 Update 2.0 from the Apple Software Updates Web site at http://www.apple.com/swupdates .
Note : 7.5 Update 2.0 installs OT 1.1. OT/PPP will not work with OT 1.1.
Note: Mac OS 7.6 does install OT 1.1.1 and has a copy of OT/PPP on the installation CD, but does not support Classic Networking. If you are experiencing the cache issue, installing Mac OS 7.6 will completely disable your MacTCP-based Internet access, and will not provide you with access to Open Transport until the REA repair is done.
Note: Most large installers available through the Apple Software Updates are available as either disk images or as "net installs." Disk images require the use of Disk Copy 4.2 to master actual floppy disks (you can get a copy of Disk Copy 4.2 in the Utilities area; many computers also include a copy on their restoration CD). A "net install" is typically a much larger file which is designed to be run from a hard drive. Which option you choose will depend on how many computers you need to install on, what kind of backup media you have, and how reliable your Internet connection to download the files is. Downloading a 20 MB file over a phone line is probably not a good idea; downloading 20 1 MB files improves your ability to recover from an error in the transmission.
Step 3
You will need to obtain Open Transport 1.1.1 or 1.1.2 and OT/PPP, both of which can be downloaded from the Apple Software Updates Web site at http://www.apple.com/swupdates .
We also recommend that you download the OT 1.1 Manual from the same area. The OT/PPP installer installs its own manual.
Both manuals require Adobe Acrobat Reader. If you do not have Adobe Acrobat installed, it can be downloaded from http://www.adobe.com .
Step 4
Installing Open Transport 1.1.1 or later will automatically switch your network connections over to Open Transport. If in the future, you wish to switch back to Classic Networking, you can do so with the Network Software Selector, an application that should be present in your Apple Extras folder.
Note: All Power Macintosh 6500, 7200, 7300, 7500, 7600, 8500, 8600, 9500, and 9600 series computers, and computers running System 7.6 or later, do not support Classic Networking, so the Network Software Selector will not be available.
Step 5
Install OT/PPP 1.0.
Step 6
The TCP/IP control panel needs to be launched, and the network connection changed to PPP. See Tech Info Library article 18238 "Open Transport TCP/IP Configuration," by clicking on this icon
for more information.
Briefly: you will need to change TCP/IP's connection method to PPP (it will probably indicate MacPPP if that was the PPP client you were previously using). You will need to specify how your computer receives its TCP/IP address (likely from a PPP server, but check with your Internet Service Provider for details), and you will need to enter the IP address numbers of your Domain Name Server(s). This information can be obtained from your service provider. Normally, if you were previously provided with this information to support a connection under MacTCP, much of this would have been automatically converted when you switch over to Open Transport.
These changes should be saved, either as part of the current configuration or as a new configuration.
Step 7
The Modem control panel, which OT/PPP installed, needs to be opened and the modem type specified.
Step 8
Launch and configure the PPP control panel. Refer to the OT/PPP User's Guide for information on how to set up OT/PPP.
