The following is the procedure I use to load Limey Linux onto a CF card. Since the CF card I was configuring in this example is significantly larger than Limey boot image, I also configured the remaining space on the CF card to be a Linux partition that can be used for additional storage (can you say audio files?). This procedure has been used to configure CF cards up to 4GB without any problems.

Once you have down loaded the image from the Limey Linux web site and un-tarred it, you need to copy the image to the CF card using the Linux '''dd''' command. '''Note: You must be root or use the sudo command for the following procedures to work:'''

The Limey Linux image has now been copied onto the CF card. We will now create a Linux partition so that remainder of the card can be used for additional storage.

The number of cylinders for this disk is set to 4036.
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)
Using the '''p''' command we can see that about 25% of the CF card is being used by the Limey Linux boot partition:

The '''n''' command is used to create a new partition. This will be a primary partition and use number 2 since 1 is the boot partition. Just press Enter for the First cylinder and Last cylinder questions to accept the default conditions which be to use the remainder of the CF card.

The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table.
The new table will be used at the next reboot.
Syncing disks.
We must now format the newly created partition. To do this we will use the '''mkfs''' (Make Filesystem) command. From above, we see that the Linux partition is located on /dev/sdc2 (the second partition on /dev/sdc). Remember, your system might have the CF card configured as a different device.

Because Ubuntu remounted the boot partition and opened a File Browser window for that partition when we finished creating the Linux partition, close the File Browser window then unmount the device as was done before.
