Chapter 1 - INTRODUCTION
1.1 PRODUCT FEATURES
The XVME-678/688 VMEbus PC/AT processor modules are designed to combine the high-performance
and ruggedized packaging of the VMEbus with the broad application software base of the IBM PC/AT
standard. These 6U, double-high modules require a single VMEbus slot, are fully AT-compatible, and
support all standard PC/AT software.
The XVME-688 features a low-power CMOS design with an 80386SXprocessor running at 25 MHz. The
XVME-678 features a Cyrix 486SLC/e running at 25 MHz. The 486SLC/e provides an internal
1 Kbyte
cache, a 486SX-compatible instruction set, and a 80386SX pin out.

Chapter 1 - Introduction
1.3.1 80386SX or 486SLC/e Central Processing Unit (CPU)
The XVME-688 uses an 80386SX microprocessor to provide operational capabilities, The XVME-678
uses a Cyrix 486SLC/e that provides a 486SX-compatible instruction set with a 1 Kbyte internal cache.
These 25 MHz CPUs can access up to 16 Mbytes of DRAM.
1.3.2 DRAM
The XVME-678/688 uses Dynamic Random Access Memory (DRAM) configured in a page interleave
mode with
0 wait-state operation. The 1, 4, and 16 Mbyte versions of the XVME-678/688 are two-way
interleaved, while the 2 and
10 Mbyte versions have no interleaving.
The XVME-678/688 comes factory-configuredwith 0, 1, or 4 Mbytes of DRAM. AdditionalDRAM can
be installed in 2, 10, and 16 Mbyte configurations. Refer to section 2.7 for more information.
1.3.3 Floppy Drive Controller
The XVME-678/688 floppy drive controller can support up to two PC/AT-compatible floppy drives.
These drives can be any combination of 360 Kbytes, 720 Kbytes, 1.2Mbytes, and 1.44 Mbytes.
1.3.4 Hard Drive Controller
The XVME-678/688 uses the IDE interface for the hard drive controller. This 16-bit interface provides
complete hardware-level compatibility to the IBM PC/AT hard drive controller. Two drives can be
connected to the interface by daisy chaining the ribbon cable and setting one drive as the master and one
as the slave. (This requires setting jumpers on the drive. Consult your drive manual for more
information.)
CAUTION
The IDE ribbon cable should not exceed 18 inches. Otherwise, errors may
occur and data may be corrupted.
Most IDE drives should never be low-level formatted. Check your IDE
drive manual for formatting procedures.

XVME-678/688 Manual
July 1994
1.3.5 Graphics Controller
The XVME-678/688 VGA graphics controller supports all IBM VGA, EGA, CGA, and MDA modes to
the register level. The VGA adapter supports Super VGA up to 1024
x 768 with 16 colors. The VGA
BIOS is
8 bits. Shadowing the BIOS through the BIOS Setup Menu (see Chapter 3 for more information)
significantly increases system performance.
The VGA controller supports IBM modes 0-13H (hex) as well as other modes. See Appendix C for a
complete list of supported modes.
1.3.6 I/O Ports
The XVME-678/688 has two RS-232C serial ports and one IBM PC/AT style Centronics-compatible
parallel port. These ports are controlled in the BIOS Setup Menu which allows the ports to be disabled
or enabled from software. Interrupts are enabled or disabled by setting bits in
I/O registers (refer to
Chapter
5).
1.3.7 VMEbus Master Interface
The VMEbus master interface allows the 80386SX CPU to become a master or interrupt handler on the
VMEbus. The XVME-678/688 master interface is invoked whenever the 80386SX accesses the VMEbus
Standard, Short I/O, or IACK address spaces. All accesses to the VMEbus are through the Real Mode
Window.
1.3.8 Keyboard Controller
The XVME-678/688 keyboard controller is PS/2 compatible and supports not only the PS/2 keyboard,
but also provides an auxiliary input port for a PS/2-compatible mouse, trackball, etc.

Chapter 2 - INSTALLATION
2.1 INTRODUCTION
This chapter provides the information necessary to configure the XVME-678/688 VMEbus PC/AT
Processor Module. It also provides informationon installingthe XVME-678/688 into a backplane, adding
extended BIOS to the XVME-678/688, adding DRAM memory in SIMM sockets, and installing an
optional math co-processor.
WARNING
If the battery is disabled in your system, please do the following: Upon
enabling, your module
must be powered up for a minimum of 30 seconds.
Failure to follow this procedure may result in premature battery failure.
WARNING
XVME-678/688 CPU modules with functional revision levels of 4.1 or
higher (functional revision levels and part numbers are located on a label
on the P1 connector) feature a 16-bit compatible PC/104 expansion site.
This PC/104 expansion site requires a new version of the XVME-956
Modular
I/O Carrier Module. If the CPU module's functionalrevision level
is 4.1 or higher, use the XVME-956/12 (part number 70956-012). If the
functional revision level is less than 4.1, use the XVME-956/2 (part
number 70956-002). Do not use the XVME-95612 on a CPU module with
functional revision levels of 4.1 or higher as this may cause damage to
both modules.
