Summary of Process
First I went and bought a usb-floppy, recommend to look at ebay and wait and have saved the $30+.
Then download the attachment above and extract that to anywhere you want.
* Plug in the usb-floppy into a working computer.
* Open the CRISDISK folder and run the program wincris.
* Check Create MiniDos Crisis Disk
– Then click Start, then OK
* A floppy format program will pop up
– Leave the Volume Label blank
– File System (Fat), and
– Default Allocation Size
– And make sure that Quick format and Create a MS-DOS startup disk are NOT checked.
* Click Start, then OK
– wait for it to finish then select OK then Close and wait again for the program to finish.
* While you wait go to
http://welcome.hp.com/country/us/en/support.html
and search up your laptop in my case (dv2910us)
download the bios update and extract the program. (Winrar can do this) look for the WPH file and rename it BIOS.WPH copy that to the floppy and overwrite the file already on there.
* Safely remove the floppy.
Now take out the battery of your laptop and unplug the power.
Plug in the usb-floppy
Press Win+B
And while doing so plug in the ac adapter
power on the laptop and you should hear 3 beeps.
Your floppy drive can be heard working
Then you will hear alot more beeps they will not be consistent so wait about 10 minutes.
If the computer does not auto shutdown by then manually do so.
Power back on the laptop with the usb-floppy unplugged and there you go.
A working laptop.
Looks like Toshibas have this problem
