PDT 3200 Technical Reference Guide
Warm Boot
The warm boot is one of two software methods for resetting a PDT 3200 unit. It is analo-
gous to the CTRL-ALT-DEL key sequence available with IBM-compatible PCs, and the
same key sequence is used to force a warm boot on a PDT 3200 unit. This method of reset-
ting a unit should be used Þrst to attempt to bring it back to a usable state.
Since a warm boot can be attempted only from a unit that has been turned on, certain as-
sumptions are made. For example, the rigorous hardware tests that are performed as part
of the cold-reset boot sequence are not all necessary; this means the unit restarts faster
with a warm boot than with a cold boot.
During a warm boot, data written to the RAM drive (drive D), the ßash drive (drive C), or
an ATA ßash PC card will remain intact. However, if an application is running on a unit
before a warm boot, its state cannot be restored.
The CTRL-ALT-DEL key sequence can be disabled, making it difÞcult for an end user to
reset the unit.
