A. If you attach a keyboard via PS/2 port after the Windows2000 installation has booted the keyboard will not work.
Service Pack 1 introduces a fix to I8042prt.sys (which can also be obtainedfrom Microsoft) which introduces hot-plugging ability assuming the BIOS supportsthis. To enable perform the following:
Start the registry editor (regedit.exe)
Move to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesi8042prtParameters
Double click Headless (or create of type DWORD)
Set to 1
Click OK
Close the registry editor
Restart the machine
