Sleep Memory Extension 1.0
Apple has identified a very rare issue that may occur when putting a
PowerBook (FireWire) to sleep. The computer may be unable to recognize
the hard drive at startup. To prevent this from happening, Apple strongly
recommends that all PowerBook (FireWire) customers running systems
prior to Mac OS 9.0.4 install the Sleep Memory Extension 1.0.
After installing the Sleep Memory Extension and restarting the computer,
the "Preserve memory contents on sleep" checkbox in the Energy Saver
control panel will be dimmed and unavailable.
Download the Sleep Memory Extension 1.0 from the Apple Software
Updates Web site at http://www.apple.com/swupdates/.
RAM Expansion
The PowerBook (FireWire) has two RAM slots on the microprocessor
board, and no RAM soldered on the I/O logic board. All units ship with a
minimum of 64 MB of factory-installed RAM. The maximum amount of
RAM supported is 512 MB. The PowerBook (FireWire) uses standard
144-pin SDRAM SO-DIMMs with a height of up to two inches.
RAM Compatibility
SDRAM SO-DIMMs used for PowerBook (FireWire) must be PC-100
compatible. Previous PowerBook G3 Series computers used PC-66 RAM
that may not be compatible with this computer.
As with the PowerBook G3 Series computers, EDO RAM should not be used.
