Some special procedure should be required for updating.
I've never liked the way, it's possible to update the BIOS from inside your OS.

We may have to go back to Boot ROMs.

Couldn't agree more - I've always wondered why they never implemented something as simple as a hardware switch (mountable on the back of the PC case and wired to the motherboard) that locks the BIOS flash chip against any software modifications to it.

Really just a simple read-only switch you'd have to physically flip before updating the BIOS.

Since that's rarely ever necessary, why leave the BIOS so vulnerable all the time?

Why did they never do a simple thing like this? Floppy disks had read-only sliders, and even SD cards still do.

I realize that the article is not referring to Windows, but if it can be done for XBox, I would think that it could be done for a Windows machine also:

My friend and I have often pondered that.

My friend and I can't believe that USB sticks don't have a "read-only" slider.

Indeed, why is this not the case right now?
