5.5
Buffer memory NVRAM
Depending on the configuration ordered, the motherboard is equipped with an NVRAM that
applications can use to back up data in the event of a power failure.
Failure of the supply voltage for a duration longer than 5 ms is indicated by the DC FAIL
signal.
Depending on the system utilization, up to 512 KB can be saved in the NVRAM.
A memory window with a maximum size of 512 KB can be displayed by means of PCI
address register. The base address is initialized by the BIOS.
A corresponding function is implemented there for using the NVRAM under WinAC RTX and
for using the CPU150xS SW controller.
5.6
Operation without monitor and keyboard
The device can be operated without a monitor and keyboard. The device startup is
guaranteed without these peripherals. A USB keyboard and mouse and a monitor can be
connected later for diagnostics.
A digital DVI monitor or DisplayPort monitor cannot be activated retrospectively unless the
Windows Embedded Standard or Windows 7 or Windows 10 Ultimate operating system has
completed booting.

Active Management Technology (AMT)
AMT (Active Management Technology) is technology for the remote maintenance of
computers (simply called AMT-PC in the remainder of the document) and it includes the
following functions:
● Keyboard Video Mouse( KVM) Redirection: Using KVM that is integrated in the AMT
hardware you access the AMT PC remotely. With KVM, you can also control AMT PCs
that have no operating system or a defective operating system. A KVM remote session is
always possible with the KVM server integrated in the firmware. This means you can
restart the PC and change the BIOS setup remotely.
● Remote power management: AMT PCs can be turned on and off and restarted from
another PC.
● SOL (Serial over LAN): Redirection of the data of a serial interface to the network. The
main use of the function is text-based remote control of an AMT PC using a console.
● IDE redirection: An ISO file on the help desk PC can be mounted on the AMT PC and
used as a DVD drive.
An ISO file contains a memory image of the content of a CD or DVD structured in the
ISO 9660 format.
● Remote reboot: An AMT PC can be booted from a bootable ISO file made available by
another PC.
