Fernando, as i have said to Nuhi many times, i have learnt everything from forums and it is nice to put something into the forums(any forum) when i can. 
My technical level is Home User Plus, i know what i need to as the average home user(plus a little bit more) and my only real experience is with the later FM2+ A88X chipset and APU’s, A8 7600 and A10 7890K. A you know, Nuhi is a Croat and he has had to correct me on my grammar serveral times(and english is my 1st language). No guide is better than a poorly written guide. I can only write a guide from the FM2+ A88X/APU point of view, which i am happy to do.
It would have to be a multi part guide because some users may buy new hardware specifically for this, some may be using hardware they already have. They have to know what hardware is suitable on the FM2+ line, AMD have CPU’s up to the 880K - 4GHZ, RAM choices, HDD or SSD. It must cover AHCI driver slipstreaming with nLite if users dont have a USB floppy drive. XP cannot correctly format Advanced Format drives and doesnt know what TRIM is. Then there are the other drivers needed, graphics(for an APU) and the other chipset drivers needed. I only know of 2 hardware combinations that installing XP works on because they were/are my own self builds, any other hardware combination is theoretical.
I will put something together with OpenOffice and email it to you(let me know which format you prefer, Word or ODT) to approve/edit and to post, you know where you want it and how it should look. xx
Edit - Fernando, ok, Word it is then. Im going to need 4 weeks to do it because of commitments and i wont be able to help rfsapiens at the same time but hopefully he has enough information to work with and will find a solution soon. xx
Edit - I will try to create a downloadable PDF guide too(i have not done this before ).
