Unhappy USB Keyboard & MSI PM8M3-V on boot up

The backlit keyboard lights up when I turn my machine on. Then it goes dark until Windows XP (or Ubuntu for that matter) kicks in later on. Which means I can't get to the BIOS with a USB keyboard. Does not seem to matter which of 6 USB ports I take. In fact, I get the impression all USB ports turn off until I get to the OS.

I'm smart, so I've always kept an old PS2 keyboard around so I can fall back on it if ever trouble came.

I've looked around the BIOS and I can't figure out how to fix it up, because it does not seem to be an option anywhere. I'm starting to think it could be a designed feature to avoid USB booting, for some reason. Like for public PCs.

Since I dual boot, it's problematic because I can't choose my OS on startup.

Make sure USB legacy support is turned on in your bios. That usually fixes it.
