ForceASPI v1.7

This page last updated: 28.August.2008. If you dropped in here from a search, you can find more detailed info about ASPI Layer Drivers posted here:> ASPI Layer Drivers.

ForceASPI is a suite of scripts designed to install v4.60 of Adaptec's ASPI layer on your 32-bit Windows operating system. Many people report that this version of ASPI layer drivers offers the BEST COMPATIBILITY with the greatest number of software programs, regardless of which Windows operating system they are used with. This nearly universal compatibility is what makes ForceASPI so attractive. Although you might not see the software as much these days, you may come across it at a online university.

ForceASPI allows you to install Adaptec ASPI layer v4.60 (1021) on your PC regardless of your hardware or software configuration.

The scripts which comprise ForceASPI automatically detect your operating system and install the appropriate files into their proper directories. The following operating systems have been tested:

Why use ForceASPI?

The reasons ForceASPI was created, and why you might want to use it:


Extract the forceASPI17.ZIP file (178KB) to a directory. Alternate link posted HERE (listed under Support Utils, near bottom). Open a Command Prompt and run the appropriate *.BAT file(s).

Usage and Instructions

Here is what each script does.

instASPI - Installs v4.60 (1021) of Adaptec ASPI layer on Win9x,
           WinME, WinNT, Win2K and WinXP. Existing ASPI layers will
           be overwritten.
dumpASPI - Creates a backup of your existing ASPI layer, or parts thereof. Some Win32 operating systems do not have an ASPI layer, in this situation you will create an empty backup. restASPI - Restores the ASPI layer backup created with 'dumpASPI'. WARNING! If your ASPI backp is empty this will completely erase your currently installed ASPI layer. killASPI - This completely removes your installed ASPI layer. killDUMP - The deletes your dumped ASPI layer.

I recommend using ForceASPI this way:


aspichk.exe is a tool provided by Adpatec to report what version of the ASPI Layer you have installed and checks if everything is working OK. To test your ASPI Layer with aspichk.exe just download it and then run it.

Here are some screenshots of what aspichk should look like after a successful install. NOTE! The number of Host Adapters detected is dependant on your hardware configuration.

RAD note: I did not write these instructions myself. This is the instruction-page (index.html) that comes with ForceASPI. If you download a copy of Force ASPI, you will find this page included with the suite of scripts. I simply post it here for your convenience. I believe the original author is the world-famous "Wimpy", but his site is no longer operating. We are all indebted to him.
