21. PC Speaker
This is a small mono low-fidelity speaker permanently attached to the
motherboard used mainly for debugging purposes. A POST beep may indicate
a successful POST, various tones for USB initialization, and other beeps to
indicate an issue during the post process. Please see Page 128 for more details.
22. VROC Header
VROC stands for Virtual RAID On CPU. The VROC header works in
conjunction with Intel
hardware key that will unlock advanced RAID functions, such as RAID5.
SATA RAID does not require a VROC key.
At the time of print, VROC is only bootable with Intel
compatible with Core
23. Rear Panel IO (Figure 2)
This is the section referred to as the I/O Hub. This panel contains the
hardwired USB, Sound, and Ethernet connections. Please see Page 13 for a
component level breakdown.
CMOS Reset Button (On I/O Panel)
This button has two main uses: the first is standard practice to clear BIOS and
power on before updating the BIOS, and the second is standard practice when
troubleshooting instances when the motherboard fails to POST, such as after
upgrading RAM or CPU, installing new hardware, a failed overclock, etc. This
button provides a much faster means of resetting than the previous method of
removing power from the board, removing the CMOS battery, and discharging
power to the board. In rare occasions the older method can help; pressing the
clear CMOS button will normally allow you and your system back into the
default BIOS.
M.2 Socket 1 Key-E 32mm
M.2 Key-E is used for WiFi and Bluetooth cards. Key-E and Key-M
connectors are mechanically different, meaning that devices are not
interchangeable between sockets.
* There are two numeric references for PCIe: one is mechanical, which is the actual slot-
length footprint, and the second is electrical, which is a reference of how many PCIe
lanes are routed to the slot.
Because PCI Express is designed to be a universal architecture, you can install x1 cards,
such as sound cards or USB controllers into an x16 slot. Many types of cards can use
PCIe SSDs. The header is used to provide an Intel
