1.20 EIDE port

An EIDE (Extended Intelligent Drive Electronics) port is provided by the chipset to connect
intelligent drives that integrate the controller (hard disk, CD-ROM etc.). This port supports
LBA (Logic Block Addressing) that allows the use of hard disks larger than 512 Mbytes. To
enhance the performance, this port supports DMA F type of transfer. The EIDE port is lo-
cated on a standard 44-pin header (2mm) for 2,5" hard disks and the compact flash con-
nector. An adapter cable is available to connect standard EIDE devices with a 40 pin IDC
header.

1.21 Compact flash connector

On the bottom side of the board a compact flash connector is located that allows the use
of compact flash cards instead of a mechanical hard disk. This socket is also connected to
the primary EIDE port of the chipset. Care must be taken when using a compact flash card
and another EIDE device (hard disk, CDROM) on the EIDE port at the same time. The
compact flash card is always the master device; the device on the EIDE port must be set
up as slave. Compact flash cards are available as solid-state disks from 4 to 300 Mbytes
and also as IBM MicroDrive up to 1 GByte.

1.22 CRT / LCD Graphic-Controller

The graphic-controller CT69000 from Chips&Technologies combines state-of-the-art flat
panel controller capabilities with low power, high performance integrated memory. It incor-
porates 2Mbytes of proprietary integrated SDRAM for the graphics/video frame buffer. The
integrated SDRAM memory supports up to 83MHz operation, thus increasing the available
memory bandwidth for the graphics subsystem. The result is support for additional high-
color / high-resolution graphics modes combined with real-time video acceleration. This
additional bandwidth also allows more flexibility in graphics functions intensely used in
Graphical User Interfaces (GUIs) such as Microsoft™ Windows™.
The CT69000 supports a wide variety of monochrome and color Single-Panel, Single-
Drive (SS) and Dual-Panel, Dual-Drive (DD), standard and high resolution, passive STN
and active matrix TFT/MIM LCD and EL panels. Up to 256 gray scales are supported on
passive STN LCD's. Up to 16.7M different colors can be displayed on passive STN LCDs
and up to 16.7M colors on 24-bit active matrix LCDs.
Vertical centering and stretching are provided for handling modes with less than 480 lines
on 480-line panels. Horizontal and vertical stretching capabilities are also available for
both text and graphics modes for optimal display of VGA text and graphics modes on
800x600, 1024x768 and 1280x1024 panels.
The CT69000 uses independent multimedia capture and display systems on-chip. The
capture system places data in display memory and the display system places the data in a
window on the screen.
The capture system can receive data from the system bus (PCI) in either RGB or YUV
format. The input data can also be scaled down before storage in display memory. Cap-
ture of input data may also be double buffered for smoothing and to prevent image tearing.
To better support MPEG2 (DVD) video decompression, the CT69000 includes a line buffer
to directly support the native format of MPEG2 data of 720 pixels wide.
