MSI Reminds You...
If you don't want to connect to the front audio
header, pins 5 & 6, 9 & 10 have to be jumpered in
order to have signal output directed to the rear
audio ports. Otherwise, the Line-Out connector on
the back panel will not function.
Front USB Connectors: JUSB1 / JUSB2
The mainboard provides one USB 2.0 pin header JUSB1 that is compli-
ant with Intel
I/O Connectivity Design Guide. USB 2.0 technology increases
®
data transfer rate up to a maximum throughput of 480Mbps, which is 40
times faster than USB 1.1, and is ideal for connecting high-speed USB inter-
face peripherals such as USB HDD, digital cameras, MP3 players, printers,
modems and the like.
