HP elitebook 8770w windows 7 64 bit.
i looked up the bios update on hp site and got this http://ftp.hp.com/pub/softpaq/sp85501-86000/sp85538.exe
i am sure its not what i currently have
i am trying to install this wwan card to use with my t-mobile sim
HP 4G lt 2510 EV-DO/LTE Mobile Broadband Module Qualcomm Gobi 4000 634513-001
yes i have read the read me first. i understand the risk, especially with HP laptops. i understand i may have a RSA signed bios (not sure if i do). yes i searched to see if there is already a whitelisted bios, i did not find a definate answer. yes, i donated $10 to the forum. any help will be appreciated.
