Hi,

Right now, I am dual-booting my n800 from a flash card. The swap is a file in the first partition of the same card, and is of 128mb.

As far as I understand, if I use a swap partition instead of a swap file, the speed of the swap memory should increase.

I am currently upgrading from chinook to diablo (from one 16gb flash to another), so I formatted my destination card as follows:
mmcblk1p1: 13500mb, fat32
mmcblk1p2: 2000mb, ext2 (system)
mmcblk1p3: 500mb, linux swap

Now, my question is how to make the system use this swap partition as default instead of the swap file. The "swapon -a" command didn't help me much (according to "free").

Any help would be appreciated

Thank you

Did you first do 'mkswap' on the partition?

BTW, from what others have said here, it doesn't make a difference anymore if you use a swap partition or a file (particularly with an SD card I should think), because the kernel will initially translate the file to the physical layer so that it sees the same as what it sees in a partition.

BTW, swapon -a will only add swap space which has been defined in /etc/fstab.
swapon /dev/name-of-swap-partition will activate it directly (and it'll last until boot)

The easiest way I know to do swap partition is with PB's excellent easy dual boot. It gives you the ability to set up swap patrtition before you do the dual boot partition. I added a 1gb partition and it really helped.

it's ok.... i didnt know about the mkswap... works fine by now
