Hi, I need to restore the BIOS on my HP tx2520ea laptop (it won't boot up/gives BIOS error), however, HP's BIOS flashing utility is a Windows-only tool. I've downloaded sp45056.exe from the HP website and extracted all the files but none are able to run from DOS. I've got a USB key with FreeDos on it, my question is how do I extract the correct BIOS file from the sp45056.exe and flash the BIOS from FreeDos? Or, is there another solution? Thank you in advance for your help, I feel a bit lost in this and really need to get my computer running again!
