Yes, the v4.60 (1021) files from Adaptec are exactly the same ASPI drivers contained in the Force ASPI package. It doesn't have an ASPI Check program included, and the ASPI Check programs from the v4.7x series drivers will give the wrong results with v4.60.
Note the following on Adaptec's web page:
This upgrade requires that either an Adaptec host adapter or an Adaptec version of the ASPI layer be installed on your system.
Previously, unless you had an Adaptec product on your computer, their ASPI drivers wouldn't load. This has changed, and starting with the v4.7x series the drivers are free of these restrictions. The v4.60 version from the Adaptec site is not unrestricted, but it may load OK because you already have Adaptec drivers loaded. It may warn you that you are replacing newer drivers with older ones, but just ignore the warning.
Personally, I would choose to use the Force ASPI installation, because it can be downloaded with a matched ASPI Check program. It also allows you to backup and restore your current ASPI drivers if you wish. It also allows the files to be installed without any Adaptec products installed, which is why this ASPI "hack" was created in the first place.
