specification and the ATAPI Specification. The Ampro Extended BIOS supports hard drives greater
than 528M bytes through Logical Block Addressing (LBA).
The Compact Flash interface is implemented as an IDE drive. If it is installed, it takes the position
of one of the drives of the primary IDE interface (settable as a master or slave drive).
PCI UltraSCSI Interface
An PCI UltraSCSI controller subsystem is available by special order. The SCSI components are not
assembled on standard versions of the Little Board/P5x. The portions of this manual that document
SCSI circuitry, software, connectors, jumpers, and hardware are relavant only on special order
versions of the Little Board/P5x that contain the SCSI subsystem.
The SCSI interface is implemented using the high speed Adaptec AIC 7860 SCSI controller
attached to the on-board PCI bus. SCSI bus termination is implemented with active terminators.
Data rates of up to 20 megabytes/second are achievable. An Adaptec SCSI BIOS is included in the
on-board Flash memory device. The SCSI interface is compatible with current SCSI standards and
is ASPI-compatible.
PCI Flat-Panel/CRT Display Controller
A powerful and flexible PCI video display controller supports both flat panels and CRTs, and offers
full software compatibility with all popular PC video standards (VGA, Super VGA, and VESA). All
standard resolutions up to 1600 x 1200 pixels and up to 16.7 million colors are supported. Refer to
Chapter 4 for detailed video specifications. 2M bytes of SDRAM video memory are standard. The
display controller features:
! High-speed PCI Architecture. The video controller provides an optimized PCI-bus path
between the CPU and SDRAM video memory.
! Graphical User Interface (GUI) Accelerator. The Chips and Technologies HiQVideo™
Multimedia Accelerator dramatically boosts the performance of Windows
® and many graphics-
intensive applications.
! Full IBM VGA compatibility. VESA DPMS and DCC standards supported.
! TV Video Display. Integrated composite NTSC/PAL support with flicker reduction circuitry.
Simultaneous TV and Flat-panel display is supported.
! Color Flat-Panel Support. Up to 16.7 million colors can be displayed on color TFT LCD flat
panels and color STN LCD panels. Uses the Chips and Technologies TMED™ algorithm to
optimize low-cost STN panel displays for 256 gray shades and 16.7M colors.
! Display Centering and Stretching. A variety of automatic display centering and stretching
techniques can be employed when running lower resolution software on a higher resolution
display. Supports 16:9 aspect-ratio panels.
! Automatic Power Sequencing Controls. The video controller provides the signals to safely
sequence the power and data signals to LCD flat panels.
! Low-Power Modes. Advanced Power Management (APM) features are implemented in the
power control logic.
! ZV Port Support. The standard Chips and Technologies ZV input port is supported.
