[1] HDMI supports DVI-D with optional adapter
[2] Unified Extensible Firmware Interface (UEFI) - required when booting from hard disks larger than 2.2 TB under Windows 64 bit operating systems such as Windows 7, Windows Vista SP1 and Windows Server 2008/2003 SP1.
[3] Integrated video outputs (HDMI and DisplayPorts)
Not all LGA1150 Intel processors may support integrated graphics. Please check the specification of the used processor. If you want to use the video outputs, then please make sure, that the used processor provides integrated graphics.
[4] Teaming Mode
The teaming function allows you to group both available network adapters together to function as a single adapter - a method of creating a virtual LAN. The benefit of this approach is that it enables load balancing and failover.
[5] Optional Wireless LAN module: this Slim PC supports an optional WLAN module, which consists of a half-size Mini-PCIe card with IEEE 802.11n functionality and an external antenna with appropriate antenna cable. Shuttle offers a suitable accessory kit "WLN-S" with two antennas.
[6] mini-SATA (mSATA)
not to be confused with the "micro SATA" connector, is a newer industry standard which converts the electrical SATA interface (1.5 or 3.0 Gbit/s) to the pysical "Mini PCI Express" mini card form factor.
[7] Caution: for high ambient temperature over 40°C we strongly recommend to use SSDs (supporting at least 70°C) and rugged SODIMM memory with wide temperature range (up to 95°C).
[8] Power on after power fail:
The BIOS setup provides a "Power-On after Power Fail" function that can be found under "Power Management Configuration". As the name indicates, this function determines the PC's behaviour after power failure: (1) unconditional power on, (2) restore former status or (3) keep system turned off. As a matter of the nature of this function, it may fail after short power failures. This is why the DS81 also comes with a hardware-based solution. By removing Jumper 4 (on the mainboard beside the hard disk LED) the system will start unconditionally once power is supplied.
[9] Optional D-Sub/VGA connector
The mainboard features one analog graphics port. This 15-pin D-Sub VGA connector can be lead to the outside of the backpanel by using an optional adapter PVG01. However doing so means one serial port (COM) less can be used at the backpanel.
