Macintosh 6360/64xx/54xx Update: Read Me

TECHINFO-0020654

TOPIC

This article contains the ReadMe file for the 6360/64xx/54xx Update.

DISCUSSION

The 6360/64xx/54xx Update corrects problems that may occur with external SCSI devices and adds support for additional Ethernet network protocols. The Update is designed for use with the following Power Macintosh and Performa models:

• Macintosh Performa 6360
• 64xx series Macintosh computers, such as the Macintosh Performa 6400 and the Power Macintosh 6400
• 54xx series Macintosh computers, such as the Macintosh Performa 5400 and Power Macintosh 5400

Fixes and Features Provided by this Update

• Fixes problems with using some external SCSI devices, such as external hard disks, scanners, or removable storage devices.

• Fixes problems with printing to a Personal LaserWriter SC or LaserWriter II SC printer. Apple recommends using QuickDraw GX and the LaserWriter II SC GX printer driver with LaserWriter SC printers because there are known problems with the non-GX LaserWriter SC printer driver. You can install QuickDraw GX from the system software CD-ROM disc that came with your computer or download the software from the Apple Software Update sites on the Internet via , America Online, or CompuServe.

• Adds support for additional Ethernet network protocols. If your computer uses the optional Ethernet CS II card to provide Ethernet networking, the 6360/64xx/54xx Update installs files that provide support for the MacIPX and Local Area Transport (LAT) network protocols.

Installing the 6360/64xx/54xx Update

1. Start up your computer.

   If one or more external SCSI devices are preventing your computer from starting up properly, turn them off before starting up. If your computer still does not start up, turn off your computer and SCSI devices. Then disconnect the SCSI devices and try starting up your computer again.

2. Double-click the Installer icon.
3. Click the Switch Disk button until your hard disk appears in the Destination Disk window.
4. Click the Install button.
5. Click the Restart button after installation was successful.
6. Shut down the computer and reconnect the external SCSI devices that you may have disconnected in step 1. Then start up your computer again.

If you are having problems starting up your computer with external SCSI devices attached, refer to the information on connecting external SCSI devices in your Macintosh user's manual, or contact the manufacturer of your external SCSI device.

Note: If you later reinitialize your internal hard disk with Drive Setup 1.1 or earlier, the fixes installed by the 6360/64xx/54xx Update will be removed, and you will need to install it again. (Most likely you will never need to reinitialize your hard disk, which was set up properly at the factory. Before you reinitialize your hard disk, see the troubleshooting information in your Macintosh user's manual for more information.)

What is installed by the 6360/64xx/54xx Update?
