swap file is gone after reboot

[lothario]

My old PC has on 48 Mb RAM.
I have done a HD install.

Before KDE starts, it tells me that there is not
enough memory and a swap file can be
created on a DOS partition.

I let it create a 300 Mb swap file in a 600 MB DOS partition.
This works fine. I use the PC for a few hours and then I shut down the PC.

Come back a few hours later and again - Before KDE starts,
it tells me that there is not enough memory and a swap
file can be created on a DOS partition. What happened
to the 300 Mb swap file we just created?

How can I make a swap file permament?

Do I need to use the DOS partition?

Can I create a swap file in the current ext3 partition?

You may create a special swap-partition.
In fdisk, you specify the partition-type 82 (Linux-swap) and call mkswap (man mkswap for correct parameters).

Thanks. That worked.
