HP Touchsmart IQ5xx series, MODDED BIOS, HELP!

Hi guys!

I need this modded BIOS in order to make my pc accept a diferent vendor's GPU.
In the past posts, back in 2013, someone had this BIOS SLIC 2.x for an IQ 820, which has the same motherboard, but the links are now dead. It was based on this original "sp43200.exe" http://ftp.hp.com/pub/softlib/software10...p43200.exe

Anyone?

Thanks in advance!
