If
“
Internal UHCI USB ports
”
are set to 0, the Internal EHCI Controller will not work, so there will not be any USB port at all. Please also consider
that Qseven
®
modules don
’
t have support for PS/2 devices (not even in case they are connected through an LPC SuperIO controller on the
carrier board), so you can use only USB keyboards and mice to interact with the system; disabling all USB ports will result in the impossibility of
interacting with the O.S. and to change again this option in BIOS setup menu. Please also check par. 4.6.1.
4.4
Chipset Configuration
After the selection of this choice, it will appear the table shown on the right:
The selections mentioned in the table are just as an example; they can be
different from default values.
4.4.1
PCI Express Slot 1 / Slot 2 / Slot3
These options allow enabling or disabling single PCI Express lanes available on
Qseven
®
Golden Finger connector. Auto option allows automatic enabling when a
PCI express device is found on corresponding PCI-e lane.
4.4.2
Internal GbE LAN
This option allows enabling or disabling the Gigabit Ethernet connection. It is also
possible to activate AUTOmatic activation of the Gigabit Ethernet interface, so that
it activates itself only when an Ethernet cable is plugged in the connector.
4.4.3
Internal EHCI USB
Internal EHCI controller allows you to use all USB ports enabled also in high
speed-mode. If enabled, EHCI controller takes control of all eight USB ports,
which can now work both in USB 1.1 and USB 2.0 mode. Please consider that if Internal UHCI USB ports are set to 0, the EHCI USB controller will be always
disabled.
4.4.4
Internal UHCI USB ports
This option allows you to choose how many internal USB ports are enabled, for working in USB 1.1 mode. Possible choices are: 0, 2, 4, 6, 8.
Total number of USB ports will depend, therefore, on the number of UHCI USB ports enabled.
