Chapter 1 – Introduction
The XVME-654 PC/AT®-compatible VMEbus processor module is designed to combine
the high performance and ruggedized packaging of the VMEbus with the broad
application software base of the IBM PC/AT standard.
Module Features
The XVME-654 offers the following features:
•133 MHz AM5x86™ CPU
•4 to 32 Mbytes fast-page EDO DRAM
•PCI local bus
•PCI local bus SVGA controller, 1024 x 768
•PCI enhanced IDE controller
•PCI to VMEbus interface
•Two 16550-compatible serial ports
•Centronics-compatible parallel port
•Optional PCI and PC/AT expansion
•On-board PCI Ethernet controller with 10BaseT and 10Base2 interfaces
•One floppy drive with a SA-450 interface
Architecture
This section describes the architecture of the XVME-654 processor module.
CPU Chip
The XVME-654 incorporates an AM5x86 processor. The CPU runs clock quadrupled at
133 MHz with a 33 MHz external bus. A unified 16 Kbyte cache using write-back
technology minimizes the time the CPU core must spend waiting for data or instructions,
accelerating business and multimedia applications.
PCI Local Bus Interface
The ALI chipset provides an accelerated PCI-to-ISA interface that includes a high-
performance enhanced IDE controller, PCI and ISA master/slave interfaces, and plug-
and-play port for on-board devices. The chipset also provides many common I/O
functions found in ISA-based PC systems, including a seven-channel DMA controller,
two 82C59 interrupt controllers, an 8254 timer/counter, and control logic for NMI
generation.

Chapter 1 – Introduction
1-2
Video Controller
The PCI bus video controller features a 64-bit graphics engine, with 24-bit RAMDAC
for true color support. Resolutions up to 1024 x 768 with 256 colors are supported. It
also incorporates the latest Green PC monitor plug-and-play features for power savings.
The video controller offers hardware-assisted video playback for Indeo™, Cinepak™,
and MPEG-1. Refer to Appendix C for information on the Super VGA modes supported.
Fast IDE controller
The high-speed local bus IDE controller supports programmed I/O (PIO) modes 0-4. It
also provides 4 x 32-bit read-ahead buffer and 4 x 32-bit write-post buffer support to
enhance IDE performance.
Caution
The IDE controller supports enhanced PIO modes, which reduce the cycle times for
16-bit data transfers to the hard drive. Check with your drive manual to see if the
drive you are using supports these modes. The higher the PIO mode, the shorter the
cycle time. As the IDE cable length increases, this reduced cycle time can lead to
erratic operation. As a result, it is in your best interest to keep the IDE cable as short
as possible.
The PIO modes are selected in the BIOS setup (refer to Chapter 3). The
Autoconfigure will attempt to classify the drive connected if the drive supports the
auto ID command. If you experience problems, change the PIO to standard.
VMEbus Interface
The XVME-654 uses the PCI local bus to interface to the VMEbus. The VMEbus
interface supports full DMA to/from the VMEbus, integral FIFOs for posted writes,
block mode transfers, and read-modify-write operations. The interface contains four
master and four slave images that can be programmed in a variety of modes to allow the
VMEbus to be mapped into the XVME-654 local memory. This makes it easy to
configure VMEbus resources in protected and real-mode programs.
Expansion Options
PC/104 and PCI Mezzanine Card (PMC) expansion is available on the XVME-654
through the XVME-976 module. The XVME-976 offers PMC and PC/104 sites,
allowing easy integration of PC/AT-compatible modules in your VMEbus system.

Chapter 1 – Introduction

On-board Memory
DRAM Memory
The XVME-654 has one 72-pin SIMM memory site, providing up to 32 Mbytes of
DRAM. The memory site can be populated by standard fast page mode memory or
extended data out memory (EDO). EDO memory is designed to improve DRAM read
performance. Using EDO memory improves the back-to-back burst timing to 2-2-2 from
3-3-3 of standard memory.
Flash BIOS
The XVME-654 board provides a location for a Flash BIOS that is used for system
ROM, video ROM, and an optional Ethernet boot ROM. The Flash socket supports a 256
Kbyte x 8-bit or 512 Kbyte x 8-bit device.
Table 1-1 describes the memory map for the 512 Kbyte Flash device.
Table 1-1. 512 Kbyte Flash Memory Map
Device Address Device System Address
70000h-7FFFFh System BIOS F0000h-FFFFFh also FFFF0000h-FFFFFFFFh
60000h-6FFFFh System BIOS E0000h-EFFFFh also FFFE0000h-FFFEFFFFh
50000h-5FFFFh Option ROM D0000h-DFFFFh also FFFD0000h-FFFDFFFFh
48000h-4FFFFh Option ROM C8000h-CFFFFh also FFFC8000h-FFFCFFFFh
40000h-47FFFh Video BIOS C0000h-C7FFFh also FFFC0000h-FFFC7FFFh
30000h-3FFFFh System BIOS F0000h-FFFFFh also FFFF0000h-FFFFFFFFh
20000h-2FFFFh System BIOS E0000h-EFFFFh also FFFE0000h-FFFEFFFFh
10000h-1FFFFh Option ROM D0000h-DFFFFh also FFFD0000h-FFFDFFFFh
08000h-0FFFFh Option ROM C8000h-CFFFFh also FFFC8000h-FFFCFFFFh
00000h-07FFFh Video BIOS C0000h-C7FFFh also FFFC0000h-FFFC7FFFh
An on-board switch controls which part of the Flash device is loaded into shadow
DRAM. This allows you to update half the Flash device and still retain a copy of the
original BIOS if the update is not successful or the BIOS is not correct. You can
determine which section of the BIOS is being used by writing to port 219h (bit 2=0) and
then reading bit 3 from port 219h. If bit 3 returns a zero, the lower portion of the BIOS is
being used.
Serial and Parallel Ports
PC/AT peripherals include two high-speed, RS-232C, 16550-compatible serial ports and
one bidirectional Centronics-compatible parallel port.

Chapter 1 – Introduction
1-4
Keyboard Interface
The keyboard interface uses a PS/2-style connector out the front panel. The +5 V is
protected with a polyswitch. This device will open up if the +5 V is shorted to GND.
Once the shorting condition is removed, the polyswitch will allow current flow to
resume.
Hard and Floppy Drives
The XVME-654’s IDE hard drive and floppy drive signals are routed through the P2
connector, providing a simplified method of connecting external floppy and hard drives.
The XVME-654 will support only one floppy drive.
When used with the XVME-977 mass storage module, the hard and floppy drives do not
have to be located next to the processor. The XVME-977 can be installed in any
unoccupied VMEbus slot, and then connected to the XVME-654 through a cable on the
J2 connectors. This allows greater flexibility in configuring a VMEbus card cage.
For applications that require mass storage outside the VMEbus chassis, the XVME-973
driver adapter module plugs onto the VMEbus P2 connector. This module provides
industry standard connections for IDE and floppy signals. You can connect one floppy
drive to the XVME-973. This drive may be 2.88 Mbytes, 1.44 Mbytes, 1.2 Mbytes, or
360 Kbytes.
Caution
The total IDE cable length must not exceed 18 inches. Also, if two IDE drives are
connected, they must be no more than six inches apart.
