Introduction

Ampro's SSD Support Software, any DOS-based application, including the operating system, utilities,
drivers, and application programs, can easily be run from SSD without modification. SSD operation is also
supported by a growing number of real-time operating systems.
The 32-pin byte-wide socket can be configured for nearly every available 28-pin and 32-pin standard JEDEC
byte-wide memory device. The socket supports all varieties of devices, CMOS SRAM, SRAM non-volatile
modules, EPROM, Flash EPROM, from 32K bytes to 1M byte and larger.
You can order models of the Little Board/P5i with a 1M byte Flash EPROM onboard. Normally the board is
equipped with a 256K byte Flash device, used for the ROM BIOS, SCSI driver, and video BIOSes. With the
1M byte Flash device, the remaining unused space can be used as an “OEM Flash device.” The OEM Flash
device acts like a second byte-wide device, and can be used for SSD or general-purpose storage.
Serial Ports
The Little Board/P5i provides four PC-compatible RS232C serial ports, implemented using 16C550-type
UARTs. These UARTs are equipped with 16-byte FIFO buffers to improve throughput.
The serial ports incorporate a unique interrupt sharing scheme, allowing for increased flexibility when
assigning interrupt channel resources.
Parallel Port
An enhanced bi-directional parallel port interface conforms to the IEEE-1284 standard. It provides new
features attractive to embedded system designers, including increased speed, an internal FIFO buffer, and
DMA transfer capability.
Floppy Interface
An onboard floppy disk interface provides access to standard floppy drives. The interface supports up to two
floppy drives, 5.25 inch or 3.5 inch, in any combination. All standard floppy drive types, from 360K 5.25
inch to 1.44M 3.5 inch are supported.
PCI-Bus EIDE Interface
An onboard PCI EIDE provides high speed hard disk and CD-ROM drive access. The interface supports up to
four IDE devices. The interface is fully compliant with AS/NSIS ATA Rev. 3.0 specification and the ATAPI
Specification. The Ampro Extended BIOS supports hard drives greater than 528M bytes through Logical
Block Addressing (LBA).
PCI UltraSCSI Interface
An onboard PCI UltraSCSI controller is implemented using the high speed Adaptec AIC 7860 SCSI
controller. Data rates of up to 20 megabytes/second are achievable. An Adaptec SCSI BIOS is included
onboard. 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 interfaces with 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 1280 x 1024 pixels and up to 16 million colors (True Color, in 640 x 480 VGA) are
supported (refer to Tables 1–2 through 1–7 for video specifications). 1M byte of video memory is standard.
A version with 512K bytes is available by special order. The display controller features:
