PCI Bus Devices
The internal PCI bus and PCI components operate at 3.3V. The PCI bus is also available to
supported docking options. These options contain their own PCI bridge.
Cardbus Controller
Cardbus support is provided by the TI1131 controller. This chip provides the following
functions:
• Support for Zoomed Video.
• Support for two PC Card/Cardbus slots with hot removal/insertion.
• Uses burst transfers to maximize data throughput on the PCI/Cardbus bus.
• Support for serialized ISA IRQs.
• Support for 16-bit distributed DMA.
• Support for Ring Indicate.
Video Controller Chip
Video support is provided by the C&T 65554 Controller Chip. This chip provides the
following functions:
• 64-bit memory interface.
• 2MB 3.3V 60ns EDO Video DRAM.
• Support for Zoomed Video.
• DDC 2B support for external monitors.
• Advanced power management features minimize power consumption during:
− Normal operation
− Standby mode
− Panel-off
PCI-IDE Controller
IDE support is provided by the CMD 643 PCI-IDE controller. This chip provides the
following functions:
• PCI bus Master device.
• Supports up to mode 5 timing.
• Supports DMA capable drives.
• Supports two IDE controllers (only one used).
