Keyboard Encoders Vs. Windows XP

[Majoraslayer]

I recently bought 3 TOKN KB10 keyboard encoders and wired one up to some of my arcade controls.  On my main computer it works great.  It includes a pass-through, so its connected as I'm typing this.

However, I can't seem to get it to work on my arcade computer.  When the PC boots, I can go into the BIOS and navigate through it without any problems.  I can also pull up the Windows boot menu via F8 and navigate that, and I can send the Windows XP installation CD into its little boot process.  However, after that Windows fails to recognize any keyboard.  I even tried a PS/2 to USB adapter, but I get exactly the same symptoms.  There were no keyboards listed in Device Manager, and once Windows XP Setup finishes loading the basic drivers from the boot CD the keyboard stops working then as well.  This leads me to believe it may be a driver problem, but why would Device Manager and the Add New Hardware Wizard both fail to detect it even being connected?

The BIOS has no keyboard settings, and this is an HP board.  Both the arcade PC and my main computer are running Windows XP SP2, so I don't understand why the keyboard won't even work during the installation process.

Any ideas?

Sounds as if this has strictly to do with that computer. Do you get keyboard input with the encoder out of the chain?

Try downloading the latest BIOS update for your computer, that may help with compatibility. Other than that, try it without the keyboard pass through. If it works without the keyboard plugged in, use a USB keyboard instead...
