PROGRAM DESCRIPTION AND USAGE 1
=====================================================================
The Interrupt 54 Adapter (I54ADAPT.SYS) is a common component for
various products distributed by Tom Donnelly Computer Software.
Interrupt 54 is used as a communication vehicle between various
products and allows products to determine if they are already
installed.
Normally, interrupt 54 is unused and there is no problem using it for
inter-program communication. However, some operating systems may not
correctly initialize this interrupt. This could cause a program to
incorrrectly think that the interrupt call should be cascaded,
leading to a system lockup. (The DOS window of OS/2 2.0 is known to
exhibit this problem.)
I54ADAPT.SYS provides an "end-point" in the interrupt 54 chain. This
insures that programs interrogating the interrupt do not incorrectly
cascade into never-never land.
I54ADAPT.SYS should only be used in situations where problems are
observed or on the advice of technical support. Symptoms of when
I54ADAPT.SYS may be applicable include:
o System locks-up during program initialization.
o On 80386 (and above) processors, a processor exception
is reported by the operating system or memory manager.
To activate the Interrupt 54 Adapter, add the following line to your
CONFIG.SYS file:
DEVICE=C:\I54ADAPT.SYS
If the file I54ADAPT.SYS is in a subdirectory, include the
subdirectory name on the DEVICE= statement.
I54ADAPT.SYS should be included once in CONFIG.SYS and before any
other Tom Donnelly Computer Software products are installed. It uses
less than 100 bytes of memory.
