VGA This mainboard includes a 4xAGP slot that provides four times
the bandwidth of the original AGP specification. AGP technol-
ogy provides a direct connection between the graphics sub-
system and memory so that the graphics do not have to com-
pete for processor time with other devices on the PCI bus.
USB (optional) The USB 2.0 Controller is compliant with Universal Serial Bus
Specification Revision 2.0.
The USB 2.0 supports data transfer rates up to 480MB/sec for
high-speed devices and specifies a microframe that will be
th
1/8 of a 1msec frame. This allows the USB 2.0 devices to
have small buffers even at high data rates.
The USB 1.1 connectors and other full speed cables can sup-
port the higher speed of USB 2.0 without any changes.
The chipset has the following advanced USB features:
•
Compliant with Enhanced Host Controller Interface
(EHCI) Specification Revision 0.95 and Universal Host
Controller Interface (UHCI) Specification Revision 1.1
•
PCI multi-function device consists of two UHCI Host Control -
lers for full/low -speed signaling and one EHCI Host
Controller core for high-speed signaling
•
Supports PCI-Bus Power Management Interface Specifi-
cation release 1.1
