Hye guys,The main thing i want to stress after read this comment is.
I'm using Compaq Presario CQ40-406au (AMD). I need to downgred my OS from Vista to XP and everybody in here really helping me. Thanks. I just want to share my problem so maybe next time if there is anybody else getting same problem as mine can solve it easily.
First time i create bootable XP using nlite it's failed. Error "...ahcix64 file corrupted..". My mistake here is selecting x64 from my sata driver. I'm suppose to select x86. But after i realize my mistake, i tried to create another bootable cd and selecting x86 but still the same error appeared. After wasting 5 of my dvd, i realize that i'm not suppose to use the same folder of win xp that i copied to my harddrive because nlite will copy and change all the setting effecting the original file of windows xp that i copied before.
Use the fresh file of winxp if u want to create another bootable cd. I already installed Xp in my compaq cq40-40au and i really want to share this with everybody. :)
1. When slipstreaming - any guide you found on the internet will tell you to create a new folder to store the windows XP files, so when you slipstream and failed, you should create another folder, don't load any previous session, create a new folder and repeat the same method.
2. The most important is to know your windows XP bootable CD/DVD, either 32-bits or 64-bits.
If 32-bits use AHCIX86 and if 64-bit use AHCI64, both type of opereating system is different even both are windows XP. If you don't know if it is 32-bit or 64-bits you can find further information here:
