I have just bought a USB keyboard to susbstitute a PS2 kb in a Win98 computer.

After installing the drivers the kb worked fine, but then every time I reboot the computer I get this error before Windows is loaded: "Keyboard error or no keyboard". But if I connect the PS2 kb again plus the USB kb and reboot and then unplug the PS2 kb after it has been detected, the USB kb works normally.

So it looks like the system tries to detect the PS2 kb before the USB kb. How can I avoid this or invert it?
