Not bad.
Here are several websites giving the methodology to modify the BIOS firmware for similar HP laptops,
so as to insert the desired information into the BIOS whitelist;
http://www.rechner.org/b1800_bios.html
http://www.richud.com/HP-Pavilion-104-Bios-Fix/
(and also gives another method, such as changing the information in the Wireless card itself to conform
with the whitelist).

That's a great tip. A bona fide freedom jumper.

WiFi lockout bypass for HP NX6125

HP NX6125 laptops have a WiFi whitelist, only allowing a certain crappy Broadcom card to work, and on all others it kindly tells you to bugger off with a different card and stop boot... but there's a way around it :

That is kinda dangerous, and today I made a less dangerous way on replacement mobo for the laptop :

The mod involves timed cutting of the IDSEL signal on the PCI connector to effectively hide the card from the system so BIOS will see nothing is present and lets you boot, but shortly after the timer runs out and enables the card again, and your OS will see it and can use it !

There's other methods that involve hacking the BIOS but I don't have a dump to check and seems nobody else has looked at it. I knew I could do the hardware way sooner and did :P
