I'm having a problem with the P8B WS and an old AT keyboard (attached to the P8B using a AT<->PS2 cable).
The Keyboard is a Flextronix Flexpro. It's a rather expensive ergonomic keyboard, which I've had for over a decade and would prefer to keep.

The problem is that when the machine boots cold, the keyboard lights flash, but the keyboard does not work. If I warm boot, then everything is fine.

I had this problem years ago with an Intel motherboard. Could not figure it out so I returned the motherboard and bought a Gigabyte mobo instead. That solved the problem back then.

I've also had the same keyboard at work for over 10 years, and 3-4 different Dell & HP desktops, all have worked perfectly.

Now, I'm on the P8B at home and I'm having this keyboard issue again.

Anyone else experience this problem before?
