*********************

|
A config.286 file is created and placed in the root directory of the specified
|
|||
|
|
drive by the instpro.bat batch stream. This file contains information for the
|
|||
|
|
protected mode operating system (OS.286 - provided by AI Architects), to assist
|
|||
|
|
in switching between real and protected mode. This file must exist in the root
|
|||
|
|
directory of any drive in which you attempt to execute PCSPRO.EXE. The instal-
|
|||
|
|
lation batch stream attempts to build the config.286 file based on the type of
|
|||
|
|
machine that it is running on. It should work with all IBM machines, but may
|
|||
|
|
have some problems when running on clones. If the system does not work as
|
|||
|
|
expected, you may edit the config.286 file and attempt various combinations of
|
|||
|
|
the options. In some cases, the options may cause a machine failure and the
|
|||
|
|
machine will need to be re-booted.
|
|||
|
|
|
|||
|
|
The following configuration options may be tried:
|
|||
|
|
|
|||
|
|
SHUTDOWN=9, KEYBOARDWAIT=200 (default, most likely to work)
|
|||
|
|
SHUTDOWN=A, KEYBOARDWAIT=200
|
|||
|
|
SHUTDOWN=9, KEYBOARDWAIT=1
|
|||
|
|
SHUTDOWN=A, KEYBOARDWAIT=1 (fastest, use this when possible)
|
|||
|
|
|
|||
|
|
|
|||
|
|
KEYBOARDWAIT Specifies the amount of time required for some keyboard
|
|||
|
|
controllers so that no interrupts are lost. Default value
|
|||
|
|
is 200 (hex). Lower values will speed up certain operations.
|
|||
|
|
Some machines may require larger values to work. Valid
|
|||
|
|
settings range from 0 to FFFF (specified in hex).
|
|||
|
|
|
|||
|
|
SHUTDOWN=(9/A) Specifies the shutdown code that is used when the machine
|
|||
|
|
is switched back into real mode. Default setting is "9".
|
|||
|
|
A setting of "A" should usually perform faster when the BIOS
|
|||
|
|
supports this setting.
|
|||
|
|
|
|||
|
|
PS2=1 Specifies that the machine is a PS2 model 50,60, or 80.

Protected mode Scheme requires version 1.03 or newer of the 8042 keyboard
|
|||
|
|
controller in your machine to work. To find out whether you have the proper
|
|||
|
|
version, we have provided a simple utility you can run to tell you the
|
|||
|
|
version number. The utility is the file VERS8042.COM on this diskette.
|
|||
|
|
If it displays a version number less than 1.03, you will need to have the
|
|||
|
|
8042 keyboard controller upgraded in order to use protected mode.

PCSPRO.EXE will run under the Hummingboard under your existing hummingboard

|
|||
|
|
we create it from the instpro.bat batch stream.

DOS CALL works somewhat differently in Protected Mode Scheme than in regular
|
|||
|
|
mode as follows:
|
|||
|
|
1. Since Scheme is running in protected mode, there is no reason for it
|
|||
|
|
to save off memory before executing the desired program. Therefore,
|
|||
|
|
the third argument to DOS-CALL (heap space to save) is ignored.
|
|||
|
|
|
|||
|
|
2. When given the form (DOS-CALL "executable-file" " args ..."), the
|
|||
|
|
executable can only be a .COM file. To bid executables which are .EXE
|
|||
|
|
files use (DOS-CALL "" "executable-file args ...").
