Yeah, it doesn't make a big difference. I just noticed this morning another
Linux machine I have that is using a type f (W95 Ext) extended partition
instead of type 5. Since you only have 2 partitions, you don't need the
extended partition, but it also isn't hurting anything.
If you run the "free" command, you should see something after Swap: that is
greater than 0.
As I said before, it will probably help the lock-up situation if you didn't
actually have any swap before.
