2.4.7 MASS
STORAGE
In a standard configuration the Compaq iPAQ supports two mass storage devices; one internal IDE
hard drive and a removeable-media IDE device (CD-ROM, DVD, or LS-120 Power Drive, etc.)
mounted in the MultiBay. This system uses SMART drives for the internal IDE device. An adapter
is available that allows a secondary IDE hard drive to be installed in the MultiBay. The MultiBay
supports hot-swapping of mass storage devices
except for hard drives
. The Compaq iPAQ
supports the DriveLock feature for MultiBay hard drives, providing enhanced security for
removeable hard drives.
2.4.8 SERIAL AND PARALLEL INTERFACES
The legacy models include a serial port and a parallel port accessible at the rear of the chassis. The
serial port is RS-232-C/16550-compatible and supports standard baud rates up to 115,200 as well
as two high-speed baud rates of 230K and 460K , and utilize a DB-9 connector. The parallel
interface is Enhanced Parallel Port (EPP1.9) and Enhanced Capability Port (ECP) compatible, and
supports bi-directional data transfers through a DB-25 connector. These interfaces may be disabled
through Setup for enhanced security. The iPAQ 2.0 system uses a snap-on legacy module for
implementing serial and parallel interfaces.
2.4.9 UNIVERSAL SERIAL BUS INTERFACE
All models feature two front panel-accessible Universal Serial Bus (USB) ports that provide a
12Mb/s hot pluggable (Plug ’n Play) interface for peripherals. Legacy-free iPAQ 1.2 models
include three additional USB ports on the rear panel while all iPAQ 2.0 models provide four USB
ports on the rear panel. taccommodate the USB keyboard and mouse supplied with those models.
Units shipped as “legacy-free” include USB keyboards and mice.
2.4.10 GRAPHICS SUBSYSTEM
All models use the graphics controller integrated into the 82810E/DC-100 and 82815 GMCH
component of the chipset. This graphics controller is the equivalent of the Intel i740 controller and
provides up to 1600 x 1200 2D resolution. Pentium III-based systems also include 4 megabytes of
local display cache for increased 3D performance. Celeron-based iPAQ 2.0 systems may be
upgraded with the addition of a 4-MB display cache module.
