For a BartPE-CD I need the driver file iastor.sys, but I can't find it neither on Intel's download site nor elsewhere on the internet.

Can anybody point me in the right direction?

This is part of Intel storage driver, you can get it here:

Intel Downloads

You want the 'Floppy Configuration Utility', either 64 or 32 depending on your requirements. You can just unzip this one, and iastor.sys should be right there :)

Hope this helps!

iastor.sys is for Intel's Matrix Storage driver. Intel mentions that you can download IATA88ENU.EXE from Intel, extract files from package which contains the the iastor.sys (albeit for an unattended install).

I've downloaded IATA88ENU.EXE. How can it be extracted? – msh Jul 30 '09 at 21:11
The Intel link that I provided says: To extract these files, run the executable (e.g. IATA88ENU.EXE for Intel® Matrix Storage Manager version 8.8) with the following command line options: -A -A -PC:\<path>, as described in the Advanced Installation Instructions section of the README.TXT. – osij2is Jul 30 '09 at 21:44
