MACHINE(HW) XENIX System V MACHINE(HW)
Name
Machine - Description of host machine.
Description
This page lists the internal characteristics of personal
computers which use the Intel 8086 processor family and its
associated hardware. The information is intended for
software developers who wish to transfer relocatable object
or executable files from other XENIX machines to a personal
computer then prepare the files for execution on the
personal computer.
Central Processing Unit Intel 8086, 8088, 80186, 80286, 80386
Disk Block Size (BSIZE) 1024 bytes
Memory Management Scheme Unmapped (8086, 8088, 80186)
Segmented (80286)
Segmented and paged (80386)
Split Instruction and Data Supported
Variable Stack Size Supported (8086, 80386 only)
(8086, 80386 default configuration)
Fixed Stack Size Supported
(80286 default configuration)
Clock Ticks .05 second (8086, 8088, 80186)
.02 second (80286, 80386)
Binary Compatibility
The small and middle model binary programs created by the C
compiler cc(CP) run on many processors. The following chart
shows which systems running on which processors produce
code executable on other machines. It is assumed that
system specific system calls are not used to produce
portable code. cc(CP) produces code by default, but can
also be used as a cross development compiler, by using the
appropriate flags.
SCO-nn is distributed by The Santa Cruz Operation, Inc.
MS-nn is distributed by Microsoft Corporation. Intel is
distributed by Intel Corporation. Altos is distributed by
Altos Computer Systems. nn designates the machine
processor. System designates the version of , either 2.3,
3.0, or System V.
