Note: Audiograbber 1.62 and higher can rip through native (internal) Windows NT and 2000 calls so an ASPI manager is no longer needed for digital ripping under NT and Win 2000. Audiograbber can however not measure possible speed problems without an ASPI manager so that meter is set to zero with native NT calls.
When being run with Windows NT, Audiograbber reads data via ASPI calls for both IDE and SCSI CD-ROMs. Unfortunately, no ASPI manager is distributed with NT, so a manual installation is sometimes required. If you have a SCSI reader you probably already have an ASPI manager installed. There is currently an ASPI manager delivered with Windows 95 and 98 which works with both IDE and SCSI drives but it may have been replaced by some other software. In case you need an ASPI manager you can find a good freeware one here that works with both Windows 95/98 and NT: http://www.grc.com/freesetuff.htm

UPDATE: The very good and reliable aspi_me ASPI manager seems to be no longer available from the above link. Maybe you can find it somewhere else on the internet if you search for aspi_me. If you find it then you need to set the data back to 1998 when you install it since the installation program checks for the date for some reason. Correct the date as soon as the installation program has started.
Here is another old one that works for windows NT:
ftp://ftp.irnet.ru/pub/Windows/NT [...] update.zip
It appears to work with NT4 even though it was written for NT 3.51. The installation instructions may however be inaccurate. You can clip out the text given below (at the end of this page) and save it as a file called aspi.reg. By Double clicking on the file the registry will be updated. Either way, be sure to read the installation instructions that came with the aspi_update.zip. Pay close attention to the ExcludeMiniports part as it is essential in making it work.
You can also try to get an ASPI manager from Adaptec at
http://www.adaptec.com Or get it directly from: ftp://ftp.adaptec.com/software_pc/aspi/aspi32.exe
Here is an article about how to install an ASPI manger without having any Adaptec hardware:
