Hello,
I have just 2 days ago built a second box of old parts and decided to give W8 a try. It runs remarkably faster IMHO than the Ubuntu 64 bit, I was using previously. Having no second drive I can not backup the system and have had to reload numerous times for undetermined reasons and general mess-ups. On my main box in msconfig > Boot Tab > Advanced tools there is a box (actually many), I don't understand. It is the PCI lock checkbox, which is checked on my W7 machine. It is not in this W8 machine and I would like to know if I should check it and possibly a elementary explanation of it's function. I am trying to learn... Thanks for any assistance!

Like all other options in msconfig, this too should be unchecked. Its purpose is to prevent Windows from dynamically allocating resources (I/O ranges, IRQs, etc) to devices connected to the PCI bus (note that devices don't actually need to be plugged into the PCI slots, many are devices that are present as part of the built-in hardware on the motherboard). In other words, if this option is checked then resources that are set by the BIOS are maintained. Note that devices, such as serial/parallel ports, may be enabled or disabled in the BIOS. Such devices, if disabled, have no resources allocated to them regardless of the PCI lock checkbox.

Hello Dwarf,
I've read up on what I could find and it seemed the one article, don't recall which, said it was better to lock the bus to the actual bios settings. So be confused to begin with, I am more so as you sure seem to know what you are talking about. Seemingly there is not going to be a gigantic performance change, I assume?
