Memory is upgradeable from 8 to 64 MB, employing 8-/16-/32-/64-MB2 64-bit soDIMMs (Small Outline Dual Inline Memory Modules). After installing the memory modules, the system automatically detects and reconfigures the total memory size during the POST routines. The following lists important memory specifications.

• Memory bus width: 64-bit

• Expansion RAM module type:144-pin, 64-bit, small outline Dual Inline Memory Module

(soDIMM)

• Expansion RAM module size/configuration:

• 8MB (1M*16x4)

You can upgrade memory using 32-MB soDIMMs when these become available. Consult your dealer.

System Introduction 1-11

• 16MB (2M*8x8)

• 32MB (4M*16x4)

• 64MB (8M*8x8)

• Expansion RAM module speed/voltage/package: 60ns/3.3v/TSOP EDO

• EDO and fast-page mode DIMMs may be used together in a memory configuration.

The following table lists all possible memory configurations.

1.4.14 PCMCIA

PCMCIA is an acronym for Personal Computer Memory Card International Association. The PCMCIA committee set out to standardize a way to add credit-card size peripheral devices to a wide range of personal computers with as little effort as possible.

There are two type II/I or one type III PC Card slots found on the left panel of the notebook. These slots accept credit-card-sized cards that enhances the usability and expandability of the notebook.

ZV (Zoomed Video) port support allows your system to support hardware MPEG in the form of a ZV PC card.
