OS: Ubuntu 7.10 x86.

During installation I had created a partition named /hdc1 for swap, but
 Ubuntu is not using it:

john at john-desktop:~$ df -h

/dev/hdc3             292G   13G  265G   5% /

john at john-desktop:~$

root at john-desktop:~# fdisk /dev/hdc

The number of cylinders for this disk is set to 38913.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p

Partition table entries are not in disk order

Any ideas on how to make Ubuntu use it?
