<b>Notable info from the Mac OS 8.1 About file...

Mac OS 8.1 CD The About Mac OS 8.1 Update file contains the following note: "When using the Mac OS 8.1 CD, the installer first runs the Mac OS 8 installation and then automatically runs the Mac OS 8.1 Update..." This seems to imply that there is no true Mac OS 8.1 Installer on the CD. It is simply a combination of Mac OS 8.0 with the 8.1 Update Installer.

Mac OS 8.1 and sound The About Mac OS 8.1 Update file contains the following notes:

Previously, audio management was determined by your computer, now your applications control audio input and output setups. There is a new control strip module which allows easier user selection of sound input source.

On PCI-based Macs: With Mac OS 8.1, the Sound control panel found in the Apple Extras folder can no longer be used to set the sound input source. Use the Monitors & Sound control panel or a new control strip module to change the input source.

On PCI-based Macs Changing the volume in the Sound control strip module will not unmute the computer. If you have selected the mute check box in the Monitors & Sound control panel, you must use Monitors & Sound to unmute the computer.
