Re: HP Probook 4540s - BIOS



Thank you so much for your reply

[B]English is not my native language so excuse my manners if I sound rude. Apologies in advance. :'([/B]

[B]Yes, I have the dump of the original BIOS[/B] but the original BIOS of 4530s does not support IvyBridge because 4530s does not have Sandy-Ivy Support and does not have the necessary GOP drivers of for GPU.

[U]Original BIOS (4530s Dump with Serial and PROD) + 2 4540s BIOS that let the system boot + FFS from 4530s that I have tried to inject[/U]
