@Lost_N_BIOS - Thanks a ton for the info. My troubleshooting and suspicion along with your guidance was indeed the solution! It took about a full minute after powering on with the newly flashed BIOS chip soldered in place, but eventually the ASUS BIOS splash screen appeared and then it eventually loaded to Windows. This model does not have build in ethernet, but I am able to see and connect to WiFi networks. Basic functions of the laptop (audio, keyboard, mouse, etc) all seem to be functioning just fine. So I suppose we just need to get the system details merged back in and then reflash? Thanks again! I’ll wait for your reply.
