It could be just that your workbench is loading a keymap on startup that is remapping things oddly. The fact that XCopy is getting proper key input should mean your keyboard is operational. Few things to try
- some other workbench disk
- while booting from workbench disk, tap a few keys as soon as the cli comes up on boot (if it does), and try to catch it before setmap happens. It will interrupt the boot process but you may be able to test out the keyboard.
