Well, there are TWO apps, a simple, GUI one:
and a complex, command line only one:
Both may or may not work on this "minimal" XP, but with a 50 % probability, you started with the most difficult/complex/undocumented one.
Possibly you can try the "DriverInjection GUI, Inject MassStorageController with click through assistant", first.
or see if you can rebuild adding this .script:
Maybe you can forget the above and see, since it is clear now that you need the iastor driver, if you can replicate this set of manual instructions:
Of course since - unike in the above - you cannot actually boot the miniXP on that machine, you will need to add the contents of the .reg file to the offline Registry.
You do know how to do this, right?
Same - more or less - goes for you, finding the dependencies is something that will need a lot of time and dedication, and it is unfortunately a CATCH22, if someone needs to ask if there are dependencies he won't be able to find them .
Seriously guys , this is a very limited environment, very, very difficult to modify, something I would not recommend (with all due respect ) to people without a solid background in modding XP, probably you would get faster (and better) results by simply using nlite wisely.
