Changes
== Hardware ==
=== fit-PC4 USB power behavior ===
USB ports power (5V) available in active (S0) state only, on all ports.
Power states:
* S0 - active<br>
* S3 - sleep<br>
* S4 - hibernate<br>
* S5 - Shut down (SW off)<br>
=== Which power supplies can power the fit-PC4? ===
fit-PC4 bundle comes with external AC/DC wall power supply, providing unregulated 10–15Vdc input voltage range, 12Vdc nominal, 36W output power for Value version and 60W output power for the Pro version. However, any power supply able to supply ~36W/60W from 12Vdc source will be fine.
When single SO-DIMM RAM memory module used it should populate the slot closer to an edge (P7) of the PCB, in order to pass memory initialization process.
=== Pigtail unterminated DC cable ===
Pigtail DC cable - unterminated on one end and on the other uses standard 5.5mm x 2.5mm barrel plug with mechanical twist-lock.<br>
Can be used with IPC2, Intense PC, fit-PC4/3 and fitlet computers.

== Software ==
=== Does fit-PC4 support VMWare ESXi ===
ESXi is reported to work on fit-PC4 incorporates Intel I211 Ethernet controllers, that are however a known to have incompatibility issue with I211 NIC driver in ESXi software.exist and addressed in few articles:We've tried to install ESXi 5* [http://blog.5 and ESXi 6kihltech.0 on several systems with no success (VMwarecom/2014/01/how-VMvisorto-Installeradd-intel-nic-drivers-to-an-esxi-5-5-iso/ "How to add Intel NIC drivers to an ESXi 5.5ISO"]* [http://www.0.update02v-2068190front.x86_64de "Why upgrading from ESXi 5.iso)5 Update 3b to 6.0 fails"]
=== Call for one-time boot selection menu ===
2. On computer start Clicking F5 will bring you into one-time boot selection menu
=== How to enable watchdog in fit-PC4 under Linux ===
fit-PC4 and fitet watchdog functionality in Linux is similar:
# Download and install [[Fitlet:_Linux:_Kernel | fitlet kernel package]] (also suitable to fit-PC4)
# Refer to [[Fitlet Watchdog #Watchdog_in_Linux | fitlet watchdog in Linux]] chapter for operation instrructions
