NOTE: Performing procedures below may corrupt your motherboard's BIOS if not done properly.  I don’t take any responsibility for anything that results from following these instructions (good or bad). You’re following these instructions at your own risk.

Let's start - this instruction is originally from HP Forum created by Justin Maslack. Download the Crisis Recovery file here.

I had to apply these instructions as I have Windows XP installed in my HP Pavilion dv2000 (dv2533) laptop. After 1.5 years, my motherboard died, I had to replace it and re-downgrade BIOS to version F.13. The seller where I bought the motherboard (PCSuperFreak on eBay) flashed the BIOS with the latest version (version F.2E at that time).

When I downloaded BIOS version F.13 and tried to install it, it won't allow it unless I have Vista installed. So, I need to convert the BIOS file to a bootable floppy version using Phoenix Crisis Recovery. I will not tackle how to create a Crisis Recovery Disk in detail. I attached the file compiled by Justin Maslack which can be downloaded here.

The file were arranged in the floppy as:

  • minidos.sys
  • phlash16.exe
  • bios.wph
  1. Get an external usb floppy drive!
  2. Extract Phoenix_Crisis_Recovery.7z file.
  3. Run wincris.exe, select minidos option, do a full format of disk (with no label), let program copy files. Make sure order is correct.
  4. Go to HP website and download the BIOS version you need. Mine was version F.13 (sp36745.exe). Unzip it on your computer.
  5. Open the unzipped folder, then go to winphlash folder and find a filename with an extension "WPH" - Usually the filename of that WPH file is described as family ROM (30CD) plus the version name (F13).
  6. Rename 30CDF13.WPH (as an example) to bios.wph. Replace the bios.wph file (on the floppy) with one for your machine if it is not dv2533.
  7. Now your Crisis Recovery disk is ready. On your laptop, hold Win+b while plugging in and pressing the power button.
  8. Keep holding Win+b until beeping starts and floppy is being read.
  9. Let the program do the rest (you should hear beeps as the disk is read, a pause break in the beeps, and then more beeps as the bios is flashed). The beep might last for 5-8 minutes.
  10. The laptop will automatically shutdown.
  11. Switch on the laptop and you should now have the BIOS version that you want!
  12. Retry if it does not work...It took me once, but some took four or five times.
