Removing an SDRAM Module
(User-Replaceable)
The Omnibook 500 has no SDRAM built in, but includes a system SDRAM slot beneath the keyboard
that contains an SDRAM module installed at the factory, and a slot on the bottom of the unit for an
expansion SDRAM module. You can use PC100 or PC133 SDRAM for these products.
