What's going on with my Linux Swap? [SOLVED]

[dave at tokyocomedy.com (Dave Gutteridge)]

I realized what went wrong with the earlier commands.
If I do fdisk, it looks like this:
   Device Boot      Start         End      Blocks   Id  System
/dev/hdb1   *           1        3644    29270398+  83  Linux
/dev/hdb2            3645        3737      747022+   f  W95 Ext'd (LBA)
/dev/hdb5            3645        3737      746991   82  Linux swap

I don't understand why it still says W95 Ext there, as I thought I 
deleted that.
But anyway, it seems my swap is on hdb5, not hdb2. If I run the 
following commands:

mkswap /dev/hdb5
swapon /dev/hdb5

And add this to your /etc/fstab: 
  /dev/hdb5    swap    swap    defaults   0 0

then it works.

I hope it's okay to run it this way.
