Port or Bus Description
Parallel port One IEEE 1284-compliant parallel port.
Ethernet port One 10/100 Mb auto-sensing Ethernet interface.
Analog audio ports The audio subsystem has two input channels that can
be sourced from the microphone input; the stereo
line-level inputs, or the internal CDROM drive analog
audio outputs. The audio subsystem has two output
channels that drive the stereo line-level outputs, and
the stereo variable-level headphone/speaker output.
Analog video ports The video subsystem has two channels and two signal
formats. The input channel can take data from a
composite input or an Y/C (S-Video) input, and the
output channel can send data to a composite output
and a Y/C (S-Video) output simultaneously.
PCI Bus There is one PCI 64-bit 33MHz PCI bus in the system
that supports the PIIX4 IDE interface and the three PCI
slots. The bus has a peak bandwidth of 266 Mbps in
64-bit mode, or 133 Mbps in 32-bit mode. There are
read-ahead and write-behind buffers that help reduce
PCI latency to memory.
