Of course you can, you can find all ASUS users manuals from the following page (for all available language):

http://www.asus.com.tw/support/download/download.aspx

You can find all files under their respective product name. i.e. You can find the P4C800 Deluxe manual as described in my last message at:

Feeling better now?

I don't understand how you have judged me as employee (or sales representative) of a particular vendor, but if you "really bother looking into the web site of motherboard vendors, can can easily find the manual and all service policies as I have discussed earlier". Below are where you can find manuals of other vendors sites:

MSI:

Gigabyte:

ECS:

Aopen:

EPOX:

Soltek:

Do you have to be the employee of a particular vendor to know what I have explained in my previous discussions? I believe the answer is clear enough, and "I do not have to waste my breath to explain the entire story to you from the beginning..."
