    Wireless keyboard problem using PS/2

    I decided to replace my PS/2 mouse and keyboard with a MS Wireless keyboard. All my USB ports are in use so I connected the wireless receiver into the PS/2 connectors using the supplied purple USB adaptor for the keyboard. The PC would not boot, not even into the POST. If I disconnected the keyboard or used a USB port it booted OK. Both the mouse and keyboard worked OK when using an USB port.
    I know the answer is to install extra USB ports but I can't work out why I should have to as the MS instructions suggest that a PS/2 setup should be fine. I've been into the bios (AMI 1008.001) but can find no keyboard reference.
    I'd be grateful for any comments.

    At a guess, the power requirements for the wireless adapter exceeds what is available on the PS/2 port and is pulling the 5V rail down.
    You may need to check the PS/2 port specification for your pc.

    Leif. Thanks for that, your suggestion certainly makes sense. I'll just have to buy a USB PC Card.

    I'd have to agree with Leif, and the lack of power provided by the PS/2. My PC has the unfortunate disability of not being able to run the USB keyboard until after Windows loads. The BIOS doesn't support the hardware. I had originally tried the keyboard / mouse combo by the USB connection.

    Trying only the PS/2, I had no mouse or keyboard control. I found I was able to use both the USB and PS/2 connections together to operation both devices now.

    Strange way to run, but it's no more connections than previously used <img src=/S/grin.gif border=0 alt=grin width=15 height=15>.
