SUMMARY
=======
The information contained in this article is taken from the SYSINI.WRI file
contained in the Microsoft Windows Resource Kit for the Windows operating system
version 3.1. The SYSINI.WRI file may be viewed with Windows Write.
The [standard] section of the SYSTEM.INI file contains settings that are specific
to running Windows in standard mode.
MORE INFORMATION
================
The [standard] section can contain the following settings:
===============================================================================
FasterModeSwitch=<0-or-1>
Default: 0
Purpose: Enabling this setting causes Windows running in
standard mode to use a faster method of switching
from protected to real mode on many 80286-based
computers. When this setting is enabled, Windows
responds quicker to hardware interrupts, allowing
better throughput for interrupt-intensive
applications, such as communications applications.
In addition, you should enable this setting if you
are using a Zenith Z-248 system and are losing
characters while typing, or if you are using an
Olivetti M-250-E and lose control of the mouse.
Note: This setting has no affect on 80386-based computers.
Some early IBM-AT and compatible computers do not
have the BIOS support necessary to use this setting.
Enabling this setting on these computers may cause
them to hang when starting Windows.
To change: Use Notepad to edit the SYSTEM.INI file.
===============================================================================
Int28Filter=<number>
Default: 10
Purpose: Specifies the interval of INT28h interrupts,
generated when the system is idle, that are made
visible (or reflected) to software that is loaded
before Windows. Windows will reflect every nth
interrupt, where n is the value of this setting.
For example, a value of 1 reflects every INT28h
interrupt, a value of 2 reflects every second
INT28h interrupt, a value of 3, every third INT28h
interrupt, and so on. Increasing this value might
improve Windows' performance, but may interfere
with some memory-resident software such as a
network. Set this value to 0 to prevent any INT28h
interrupts from being reflected. Setting this
value too low (from 1 to 9) might interfere with
communications applications.
To change: Use Notepad to edit the SYSTEM.INI file.
===============================================================================
MouseSyncTime=<milliseconds>
Default: 500
Purpose: Specifies the number of milliseconds that can
elapse between mouse data bytes before Windows
running in standard mode assumes that a mouse data
packet is complete. This setting only affects
Windows running standard mode on computers with an
IBM PS/2 mouse interface.
To change: Use Notepad to edit the SYSTEM.INI file.
===============================================================================
NetHeapSize=<kilobytes>
Default: 8
Purpose: Specifies the size (in kilobytes) of the data-
transfer buffer that standard-mode Windows
allocates in conventional memory for transferring
data over a network. If an application is not
running correctly, your network may require a
larger buffer than the default. Increasing this
value will decrease the amount of memory available
to applications. If no network software is
running, this setting will be ignored and no
memory will be allocated.
To change: Use Notepad to edit the SYSTEM.INI file.
===============================================================================
PadCodeSegments=<0-or-1>
Default: 0
Purpose: Setting this value to 1 causes Windows kernel to
pad code segments with 16 bytes. This will prevent
the last instruction in the segment from being too
close to the segment limit for 80286 C2 stepping.
Set this value to 1 if your 80286 system hangs in
standard mode.
To change: Use Notepad to edit the SYSTEM.INI file.
===============================================================================
Stacks=<number>
Default: 12
Purpose: Specifies the number of interrupt reflector stacks
used by the standard mode MS-DOS Extender (DOSX).
Interrupt reflector stacks are used when the MS-
DOS Extender needs to map a DOS or BIOS API from
real mode to protected mode. If you receive a
"Standard Mode: Stack Overflow" message, try
increasing the number. You can specify a number
between 8 and 64.
To change: Use Notepad to edit the SYSTEM.INI file.
===============================================================================
StackSize=<bytes>
Default: 384
Purpose: Specifies the size of the interrupt reflector
stacks used by the standard mode MS-DOS Extender.
To change: Use Notepad to edit the SYSTEM.INI file. (You
should never need to change this setting.)
