There is also a file config-2.4.21-0.13mdksmp.
On boot up, there are options for linuxsmp and linux. I use linux. I don't know why MDK installed the SMP option as the PC has only one P4 CPU.
cat config-2.4.21-0.13mdk | grep -i dvi
cat config-2.4.21-0.13mdk | grep -i smp
#CONFIG_SMP is not set
BTW, noting Andy's post, this is a desktop PC, not a laptop.
