3.4 HORM
HORM stands for Hibernate Once/Resume Many. Devices with HORM enabled can
be quickly shut down and restarted into a preconfigured state, even in the event of a
sudden power loss.

Important
To setup a HORM environment, follow the steps below.
– Ensure UWF is enabled.
– Ensure that the volume(s) is protected.
– The system must not have any file, folder, or registry exclusions configured
for UWF.
– The UWF overlay must be set to RAM-based mode because HORM does not
support disk-based mode.

Note
HORM cannot be used on a Unified Extensible Firmware Interface (UEFI)
device. The installation procedure for UEFI always creates a hidden system par -
tition and the UWF cannot protect hidden partitions. Because HORM requires all
fixed partitions to be protected, HORM cannot be used on any devices that con -
tain a hidden partition, including UEFI-capable devices.
