This is through certain reading from different forums. Finally my laptop is working good.
This instruction is for HP Pavillion dv2533 (to be exact), but might be helpful with other laptop models in dv2000 series.
This instruction is not for dv6500, I saw an interesting instruction here for that model http://forum.notebookreview.com/showthread.php?t=119155.
Note: HP release a Limited Warranty Service Enhacement as they identified a hardware issue with certain HP Pavilion dv2000/dv6000/dv9000 and Compaq Presario V3000/V6000 series notebook PCs. Check it out here.

 


REQUIREMENTS:

1. BIOS vF.13 - sp36745.exe (download here)
2. RAID driver - sp37005.exe (download here)
3. floppy (to install the RAID driver) & external USB floppy drive or USB flash drive (If you don't have floppy, you need to slipstream the RAID drivers with Windows XP setup files)
4. Windows XP CD
5. drivers for Windows XP

 

Or you can also check this link for some drivers from HP website for Pavilion dv2000.



INSTRUCTIONS:


1. I am assuming that you have Vista installed in your laptop. Downgrade your BIOS to version F.13 from F.21 or whatever BIOS version you have. To do this you should have Windows Vista installed. You can see the BIOS file from the ZIP installer included in this package. Then restart your computer.

If you don't have Vista installed and you preferred to install the BIOS using a bootable floppy, please read on how to modify the BIOS and save in your floppy.

2. Plug your floppy drive in your laptop. You can use a USB flash drive if you don't have USB floppy drive. Install sp37005.exe (RAID drivers) in your floppy or USB drive. If you don't have floppy drive or USB drive, you need to use nLite to make a new Windows XP CD with RAID drivers in it.

3. Now insert your Windows XP (bootable CD) to your CD-ROM. Restart your PC. Make sure you configure the BIOS being the CD-ROM as the first boot.

4. At the very beginning of Windows XP installation, the following prompt is displayed at the bottom of the screen:
"Press F6 if you need to install a SCSI or RAID driver..."

When the prompt is displayed, press F6.

5. Later in the operating system installation, you are notified that a mass storage device could not be detected. When this notification occurs, press S (S=Specify Additional Device).

6. When prompted, press Enter.

7. Select "Intel 82801HEM/HBM SATA AHCI Controller (Mobile ICH8M-E/M)".

8. Continue with the XP installation, as promted.

9. Once, the installation is finished, install all of the drivers.

10. Done!
