USB Keyboard Disable before Installing Redhat
 

I use USB keyboard. When I attempt to install Redhat 7.3 from CD1, just after booting from CDRom , I press ENTER to start installing, and my keyboard become disable. It's impossible to finish setup without keyboard, for I should type a root password during the setup process.

After trying for several times, I find that every time when executing the command line 'uhci' just before install, the Num Lock turn off and I am sure that it's the time my keyboard came wrong. What's the solution?

About my Computer: The PS/2 keyboard port on my mainboard is not available. Without buying a new mainboard, instead , I use usb keyboard. It's all OK during WindowsXP or DOS for there is a 'USB keyboard Support' in CMOS.

I have tried Redhat 9, but similar problems appear.
