For your K40IJ notebook computer with Intel chipset, you have 2 options for the XP installation.
The first one is to get into the BIOS. Select Advanced >> IDE Configuration >> SATA Operation Mode >> Compatible/Enhanced (default is Enhanced). Change to Compatible. Save and exit BIOS. You can start the XP installation now. The demerit of this option is the performance of the hard disk will be less efficient, as it is of the SATA system.
The other option is very good, but more complicated. It is to use the program nLite to integrate the SATA driver, Service Pack 3 components, and Internet Explorer 7 into the XP installation CD, and make a new XP sp3 CD. This can also meet the requirement that it is necessary to use XP sp2 CD or newer version for the XP installation on ASUS notebook computer.
Here is the way to do it.
Get the Service Pack 3 components, WindowsXP-KB936929-SP3-x86-ENU.exe from here, and put the file under C:\
