Extensions
http://www.AmbrosiaSW.com/DEF/PP/ext.html Friday, September 5, 1997
identically-named extension which gets installed; in this case, it would be the one that's put in after an installation. So it never gets to do its
thing, and subsequently never deletes itself. You should make sure that if you install Apple software and the Installer Cleanup extension is
"installed," that you allow it to load at the very next startup. It should disappear. On the other hand, sometimes it doesn't disappear no matter
what you do. If you still have this extension after several restarts, or if you just find it sitting there, and everything seems to be working
fine, you should be able to trash it.
Internal Modem Sound PM: on 5200, 5300, 6200, and 6300 series Macs, this file fixed a problem with internal Global Village modems
where no modem sound was heard. It is now a part of the Audio Volume Extension (see above).
Intelligent Battery Update: updates the battery manager on 500-series computers (actually updates the batteries themselves). The 500-series
batteries have a microprocessor built into the battery to monitor the battery's "vital signs." Sometimes the data inside this microprocessor
becomes corrupt and causes the System software to receive incorrect information about the battery's status (power remaining, etc.). This
extension, along with the Intelligent Battery Recondition application, updates the information in the battery's microprocessor. It should be
used if you experience any of the following symptoms: the PowerBook fails to recognized the battery; the battery will not charge; two
batteries are installed, but only one is recognized; at least one battery is installed, and the "battery monitor" control strip module shows the
icon of a plug and a right facing triangle. NOTE: the application only works on the battery in the right-hand battery bay. If you have two or
more batteries, you will have to use the application once for each battery by placing each one in the right-hand bay.
IR Talk: only used by the 500 and above series PowerBooks with an InfraRed port. Allows AppleTalk connections through the IR port
using the AppleTalk/Network control panels.
LC Monitors Extension: adds functionality to the Monitors control panel for LC series Macs.
Letterhead: part of the QuickDraw GX package, this extension enables the "Letterhead" paper type option in the "Page Setup..." window of
compatible applications.
LocalTalk DMA (v1.0.1): part of the obscure "System 7.5.3 Revision 2.1," this file fixes a bug with transferring files over LocalTalk on
Performa 6400/180 and 6400/200 computers. This fix is supposedly included in the System 7.5.5 Update, and should no longer be needed.
Macintosh Drag & Drop: see Drag&Drop Extension above.
MacTCP Token Ring Extension: allows you to use the TCP/IP protocol over a Token Ring network.
MODE32: under System 7, gives the Mac II, IIx, IIcx, or SE/30 the ability to run in 32-bit addressing mode. All other Macs either have
32-bit addressing capability built into the ROM, run in 32-bit addressing mode all the time (AV models, PB 500s, and all PowerMacs), or
are incapable of running in 32-bit addressing mode (running System 6 or have a 68000 processor). With 32-bit addressing "on," your Mac
can take advantage of more than 8MB of RAM. Under System 7.5, a new version of MODE32 was released. You MUST use MODE32 7.5
if you are running System 7.5.
Mount IDE Drive: allows Macs with IDE hard drives to mount these drives when the Mac is booted from another disk or device.
