So, here is the story: I have a laptop Acer Aspire 5100, which has a dead southbridge. In any operating system it predictibly results in non-working audio, usb, keyboard and touchpad. I tried Windows XP, Windows 7, Linux and FreeDOS. They all work ok on it except this minor stuff. I also obvioulsy can't access BIOS since keyboard is dead. And if I install FreeBSD on it ofcouse I cant skip that autoboot delay with the boot menu. But if system boots - the keyboards suddenly works like a charm, and that makes my laptop totally usable and fine (for example to set up ethrenet switches using cardbus serial adapter). That's a miracle! Or is it? So the question is: what makes FreeBSD so different? How does it work with the keyboard and why no other OS uses this method then? P.S. I even made the video about this situation and it has an image of this laptop's motherboard if needed. Here it is: https://youtu.be/JBt_fbvpGww
