SI - System Information

Summary

System Information displays technical information regarding your hardware and operating system.

Usage: SI

Description

SI displays some of the information which OS/2 maintains on your system. The items which it returns are:

Machine Type

This field reports on the type of the machine. If possible, it will list the class and type of the machine.

Operating System

This field reports on the Operating System version which is currently running.

OS/2 boots from

The drive on which OS/2 was installed and started from.

Country Code

This is the country code setting for the current session.

Country Code Page

This is the current country code page (or character set) setting for the current session.

Maximum sessions

The maximum number of sessions available, for both Presentation Manager and VIO or Full Screen sessions.

Maximum VIO sessions

The maximum number of VIO or Full Screen sessions.

Maximum PM sessions

The maximum number of Presentation Manager sessions.

Max Wait

This field specifies the maximum number of seconds which a process has before the OS/2 schedular devotes CPU time to another process. This parameter is configured in the CONFIG.SYS file.

Timeslice

This field specifies the Maximum and Minimum time slice of the system. The priority is also listed - it is either Absolute or Dynamic. The timeslice parameters dictate the length of time which the OS/2 schedular uses. If a thread uses up its entire timeslice, it must be pre-empted. The next timeslice for that thread is one tick longer, up to the specified maximum. If the priority is dynamic (the system default), the priority of threads can be adjusted by the system, to ensure that all processes receive some CPU. If the priority is absolute, thread priorities can not be adjusted, and the MaxWait parameter has no effect.

Timer Interval

This field details the system timer interval. It is specified in micro seconds (uSec).

Current Video Mode

This shows the details of the current video mode. It will return information in the form of: <Text/Graphics>, Columns x Rows Colour/Monochrome

Co-Processor

This field reports on whether or not you have a maths co-processor installed. Remember that OS/2 2.x will emulate one if necessary. Therefore SI will report one even if you do not have one installed.

Parallel Ports

The number of parallel ports available to the system.

Serial Ports

The number of serial ports available to the system.

System up since

The last time that the system was booted. An example is:

Fri Jan 07 21:00:15 1994

Note : This time will wrap around after approximately 45 days.

Valid Drives

A list of the valid disk drives available to the system - both local and remote.

Current Adaptor

This field displays a comment on the current video display adaptor. The predefined values are:

Monochrome/printer adaptor

Colour graphics adaptor

Enhanced graphics adaptor

Video graphics array display adaptor

IBM Personal System/2 display adaptor 8514/A

Image Adaptor

XGA graphics adaptor

Super video graphics array display adaptor

Unknown display adaptor (unknown code)

The unknown code will be displayed as a number. This indicates that the value is one reserved for future adaptors.

Current Display

This field displays a comment on the current video display. The predefined values are:

Monochrome display

Colour display

Enhanced colour display

8503 monochrome display

8512 or 8513 colour display

8514 colour display

IBM plasma display

Monochrome 8507 or 8604

8515 display

9515 display

9517 display

9518 display

OEM display

Unknown display type (unknown code)

The unknown code will be displayed as a number. This indicates that the value is one reserved for future adaptors.

Display Adaptor Memory

The size of the video memory on the current display adaptor in bytes.

ANSI processing

This reports on whether ANSI escape sequence processing is on or off for the current session.
