2.4.5 MASS STORAGE
In a standard configuration the Compaq iPAQ supports two mass storage devices; one internal
IDE hard drive mounted on the right side and a removeable-media IDE device (CD-ROM, DVD,
or LS-120 Power Drive, etc.) mounted in the MultiBay on the left side. 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.

The legacy-light 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

2.4.8 GRAPHICS SUBSYSTEM
All models use the graphics controller integrated into the 82810e/DC-100 GMCH component of
the 810e chipset. This graphics controller is the equivalent of the Intel i740 controller and
provides up to 1600 x 1200 2D resolution using the AGP 2X interface. Pentium III-based systems
also include 4 megabytes of local display cache for higher 3D performance.
