DriveLock Password
These systems support the DriveLock security feature for a compatible hard drive installed in the
Multibay. When enabled, DriveLock prevents unauthorized access to hard drive data by requiring
either a master DriveLock or a user DriveLock password to be entered. Although this function is
controlled through the Setup utility, the password information is stored in a reserved area on the
hard drive so that the password(s) will stay or move with the drive.
CAUTION: The DriveLock feature is designed primarily for business environments
where removable hard drives may be moved from system to system. Since forgetting both
DriveLock passwords for a particular drive will result in the data on that drive being no
longer accessible, it is strongly advised that this feature be invoked and managed by a
system administrator. For detailed user information consult the appropriate user reference
guide for this system.
4.6.1.2 Cable Lock Provision
These systems include a chassis cutout (on the rear panel) for the attachment of a cable lock
mechanism.
4.6.1.3 I/O Interface Security
Serial, parallel, and (on iPAQ legacy systems) the USB interfaces may be disabled individually
through the Setup utility (F10) to guard against unauthorized access to a system. On iPAQ 2.0
systems the NIC interface may also be disabled through Setup.
4.6.2 POWER MANAGEMENT
The iPAQ 2.0 systems provide baseline hardware support of ACPI- and APM-compliant firmware
and software. Key power-consuming components (processor, chipset, I/O controller, and fan) can
be placed into a reduced power mode either automatically or by user control. The system can then
be brought back up (“wake-up”) by events defined by the ACPI specification. The ACPI wake-up
events supported by this system are listed as follows:
ACPI Wake-Up Event System Wakes From
Power Button Suspend or soft-off
RTC Alarm Suspend or soft-off
Wake On LAN (w/NIC) Suspend or soft-off
PME Suspend or soft-off
Serial Port Ring Suspend or soft-off
USB Suspend only
Keyboard Suspend only
Mouse Suspend only
