The chipset and processor indicate that we deal with Intel’s new Centrino platform (also known as Sonoma), but there should also be a WLAN adapter. The OpenBook 1559-JL really has a dual-range Intel Pro/Wireless 2915ABG WLAN module that supports IEEE 802.11a/b/g standards.

Talking about the new Sonoma platform, the chipset is completed with a new South Bridge, ICH6-M. Besides other things, this South Bridge supports two Serial ATA ports, eight USB 2.0 ports, and Intel High Definition Audio. The most interesting feature of this Bridge is, however, the new standard of expansion cards for notebooks, Express Card. The Express Card bus is a combination of PCI Express x1 and USB and is going to replace CardBus in medium-range outlook. Express Card slots will be placed outside the notebook’s case for connecting various peripheral devices.

The OpenBook 1559-JL also has a Gigabit Ethernet controller, an analog modem, a FireWire controller, and a card-reader. The formal specification of the barebone looks as follows:

To transform the OpenBook 1559-JL into a full-fledged mobile computer, you need to install a central processor, memory, and hard and optical drives.
