You have to remember that you are dealing with TTL level signals, usually without any buffer between the keyboard connector and the keyboard controller. While it doesn't happen that often, you can damage the keyboard controller in the computer by hotplugging a keyboard. This is usually because of static damage, but it can be because you short pins... One of my favorate warning on this is "Because PS/2 hotplug is not in the PS/2 specification, some PS/2 controllers may not correctly handle "hotplugging" of a device, and some may short out devices." Mikkel -- But if it was a hardware problem the keyboard shouldn't work anywhere; however the keyboard still works perfectly in the bios and in windows safemode. It only fails when attempting to install fedora or after windows (normal boot) has booted up. In addition to this I have tested several other keyboards, all of which were tested on other computers in working order to ensure that they themselves were in working order. -Jerome -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
