After several hours practice, I have successfully changed my HP Pavilion DV4 1103TX OS from Vista to XP. Now let me introduce my experience when you install the XP OS to your Pavilion DV4 1103TX.

I bought my HP Pavilion DV4 in April 02 in HP store. To avoid some trouble, I decide install XP into my Notebook in April 19 ( 15 days after I buy the notebook, as the HP supply the 15 days free replacing ). Please notice this :The HP Pavilion DV4 hard disk is the ICH9 SATA DISK. Some XP OS edition driver cant support the ICH9. I tried many XP OS edition to face the situation.

To ensure the OS change cant effect the HP quality warranty. I called the HP customer center to query the problem. They said that they are not accountable to the broken of userself bios fresh, but they say I can change my notebook OS to XP SP2 without bios freshing. But when I finished my XP SP2 install, the voice card driver cant work. So I must fresh my bios, you only need to notice that dont interruption of power supply when you fresh BIOS.

Please notice that : Please fresh the F11C BIOS program before you install the XP OS, or you must reinstall the OS again.

Now let me install the XP SP3 into my Pavilion DV4 step by step:

* First download or buy ICH9 XP SP3 CD (the CD must be ICH9 XPS SP3), you can google it

* Then prepare the F.11C-BIOS fresh program. Fresh the F.11C-BIOS here : http://www.icare.hp.com.cn/TechCenter_StaticArticle/45904/59726.zip
The BIOS only can be freshed in DOS.

* Next you only to install the XP SP3 into your notebook in standard step. Dont care of the black screnn when installing.

* After finish the install, you can go to XP edition desktop to fresh all the driver.
