The Extensions folder

' OSBooster Extension' Obviously this extension is critical for OSBooster to function. Users of Apple's Extensions Manager should not turn it off in either their normal extensions set or the OSBooster set. Users of Conflict Catcher should only have OSBooster in their OSBooster extensions set.

Apple CD/DVD Driver needed if you intend to use CDs or DVD drives with OSBooster.

Apple Enet only needed if your Mac is connected to an ethernetwork and you need to use that interface with OSBooster.

Apple Guide is not essential.

Apple QD3D HW Driver &Apple QD3D HW Plug-In These are needed by many games.

AppleScript &AppleScriptLib may be needed by some applications, particularly servers - otherwise, safe to turn off.

AppleShare is only needed if you need to share or access shared folders over a network.

Application Switcher is definitely not needed by OSBooster. (Allows user to command-tab between applications.)

Built-In Graphics Accelerator improves graphics performance of your Macintosh. Do no turn off.

Color Picker & Color Sync Extension Not normally needed. Might be used by some graphic design packages.

Contextual Menu Extension Unlikely to be needed by most applications. Turning it off will not cause any applications to fail.

Control Strip Extension. This may be useful to you, however it does slow down the Macintosh, we recommend turning it off. Some applications turn it off automatically. If this is the case, you should turn it off in the extensions set as it may still be affecting performance.

Default Calibrator is very unlikely to be needed except by graphics professionals. Turn it off.

Desktop Printer Spooler &Desktop Print Monitor only needed if you have desktop printers and you need to use them under OSBooster.

DNSPlugin is only needed if you are connected to a TCP/IP network that provides Dynamic Name Services and you need to use that network with OSBooster.

Emulator Update Extension This extension was released with the latest version of Macsbug. It may improve the performance of the 68K emulator, and should probably be left turned on.

FBC indexing scheduler is used by the 'Sherlock' application. Very unlikely to be needed. Turn it off.

File Sharing Extension &File Sharing Library Only turn these on if you need to use file sharing with OSBooster.

Find by Content. Another part of 'Sherlock'. Again we recommend turning this off.

Folder Actions allows AppleScripts to be run in response to events happening to folders. Normally turn this off.

Foreign File Access. If you are using your CD or DVD drive with OSBooster, leave this turned on.

Internet Access helps applications find out what your internet settings are. Only turn this on if you need to access an internet with OSBooster.

Iomega Driver. Leave this on if you need to access Iomega zip or Jaz drives.

Location Manager Extension. Unlikely to be needed.

Microsoft Component Library &Microsoft Font Embed Library (PPC) are used by Internet Explorer - only turn on if needed.

Network Setup Extension. Only leave turned on if you need to use networking.

Norton Shared Lib. We recommend turning off all Norton Utilities.

Open Transport etc... These files are only needed if you need networking. Although some applications that use networking may fail if these are turned off - even if you are not using networking in that application. RealPC will not run if these files are turned off.

OSBooster Stub This is critical to OSBooster. You should always have it enabled in your normal extensions set and the OSBooster set. It has no effect whatsover when OSBooster is not running so there is no memory or speed penalty in leaving it enabled.

Printer Share allows other networked computers to see a printer connected to your Macintosh. We recommend turning this off when using OSBooster.

PrintingLib &PrintMonitor Again, only needed if you need to print with OSBooster.

QuickDraw™ 3D etc... May be needed by games and/or your graphics card.

QuickTime etc... Needed by many applications. It is unlikely that you should need to turn these off.

Remote Only is needed by Remote Access - only turn on if you need to use Remote Access.

Serial (Built - In) is only needed if you are using Open Transport (networking) over your serial ports.

Shared Library Manager &Shared Library manager PPC are needed by Open Transport (networking) and some other applications. Probably best to leave this turned on.

SLPPlugin is needed by some obscure networking applications. Generally safe to turn it off.

SOMobjects Needed by some applications especially those using contextual menus and OpenDoc. Otherwise turn off.

Sound Manager should be left turned on.

Speech Manager should only be turned on if needed.

StuffIt Engine™ &StuffIt Engine ™ PowerPlug used to compress and expand archives. Unlikely to be needed.

Text Encoding Converter (MacOS 8.0/8.1) is needed if you have HFS+ volumes.

Time Synchroniser only needed for time synchronisation with network time servers. Turn off.

UDF Volume Access needed only if you wish to use your DVD drive with OSBooster.

Video Startup only needed if you intend to use the Apple Video Player application with OSBooster.

°AppleVision only needed if you have an AppleVision monitor and need to use the on screen controls.
