Features - Aaeon SBC-456 Manual

The SBC-456/456E is an all-in-one single board 486 computer with an
onboard flat panel/CRT SVGA controller and PCI Ethernet
interface (SBC-456E). It packs all the functions of an industrial
computer and its display capabilities onto a single, half-size card.
This means the SBC-456/456E is your absolute best solution for
embedded applications.
The onboard PCI-bus, flat panel/CRT SVGA controller uses the
CHIPS 65550 chipset with up to 2 MB of video memory (onboard
1MB). This chipset, used with the local PCI-bus, enables 32-bit
graphic throughput at up to 33 MHz. Excellent for display-intensive
applications, it supports various LCD types including TFT, STN, B/
W, and EL.
The onboard Ethernet Realtek RTL 8029AS PCI bus Ethernet
controller supports remote boot ROM functions (SBC-456E only).
The SBC-456/456E supports the M-Systems DiskOnChip 2000
(optional) which is a new generation of high performance single-
chip Flash Disk. It provides a Flash Disk (as a BIOS expansion)
which doesn't require any bus, slots, or connectors. It is also the
optimal solution for Single Board Computers because of its small
size, easy integration, plug-and-play functionality, and its low power
consumption. The DiskOnChip is available in capacities from 2MB
to 144MB and fits in a standard 32-pin DIP socket.
Another feature of the SBC-456/456E is the inclusion of a high
speed, local bus IDE controller. This controller supports (through
ATA PIO) mode 3 and mode 4 hard disks, enabling data transfer
rates in excess of 11 MB/second. Up to four IDE devices can be
connected, including large hard disks, CD-ROM drives, tape backup
drives, or other IDE devices. The built-in, enhanced IDE controller
provides a 4-layer, 32-bit, posted write buffer and a 4-layer, 32-bit
read-prefetch buffer to boost IDE performance.
