keyboard. It supports the Intel Pentium M (Banias)
processor and Intel Montara-GM/ICH4-M chipsets
with 400MHz CPU bus(FSB). The system features
include on board Wired LAN(Intel 82562EZ),
MDC(Modem Daugther board Card) using AC
link, internal mini-PCI wireless LAN card, 4-pin
1394 port supports external 1394 devices, 2 USB 2.0
ports, 2 DDR SDRAM SO-DIMM memory slots, a
large capacity hard drive and ODD(CD-ROM, CDRW, DVD-ROM, DVD/CD-RW COMBO, DVDR/RW, DVD-Multi). The system features Ricoh
R5C593 supports Card Bus, 1394 and Memory
Stick.
