It's always active, no extra software requried.
I've made several adapters over the years, and I don't have all the manuals still available. Please post a picture of the exact model, and I'll look for a file. I have a backup of the old DOS/Win3.1 machine with Word6 that I've used back then to write manuals.
Thanks for quick reply. Always active without extra software is logical and too my idea BUT my friend has IDE-FIX rev.2 with express adapter (latest icomp version 2002?) where works (is active) 2,5" port 0 with 2,5" HDD only after run command C:idefix
Without software is this 2,5" port 0 not active.
