NOTE:
SPM uses Interrupt 4 and I/O address 3F8 for COM1. It uses Interrupt 3
and I/O address 2F8 for COM2.
Installing the SPM Software
2
Before you install or run SPM, it is recommended that you use diskcopy on a DOS
PC (see your operating system guide) to make a backup copy of the SPM disk.
Store the original in a safe place. Use the backup copy to run the installation
program.
For installing DOS SPM on a PC, follow the appropriate instructions in the next
section. For installing DOS SPM on a Windows 95 PC, follow the instructions
provided in
‘‘DOS Installation with Windows 95’’ on page 2-6
.
NOTE:
If your PC does not have a hard disk, you do not need to run the installation
program. Go to
‘‘Initializing the SPM Software’’ on page 2-10
.
DOS Installation
2
Use the following procedure to install SPM on the hard drive of a DOS PC.
NOTE:
If you are updating SPM, you do not need to remove the current SPM files.
The new files will overwrite your current SPM files.
Considerations
2
Review the following items before you begin the installation procedure.
The installation program automatically performs the following:
■
Checks available space on the hard disk. If space is insufficient, the
installation is terminated and an error message is generated.
■
Checks the autoexec.bat and config.sys files. If either file is
write-protected, the installation is terminated and an error message is
generated. SPM must make changes to these files.
■
Saves a copy of autoexec.bat as autoexec.old.
■
Saves a copy of config.sys as config.old.
■
If autoexec.bat has not already been configured for SPM:
— Adds
c:\spm
to the path statement.
