Kernel copy

[resole83]

Hi guys!
I have a little problem...
I'm working with some RouterBoard 502 Wifi and I use a kernel linux compiled "at art" in a USB flash card USB (1 GB) and all works correctly...
In the lab today was arrived some new box and new flash card...so now I need to copy everything there is in the old flash card (kernel linux) in the new cards...
The problems are:...
-) how can I do the partition for new flash card?
-) how to re-copy exactly the linux kernel and everything from the oldest flash card to the newest?
Here there is an output of fdisk with oldest cards.

syncron@syncron-laptop:~$ fdisk -l /dev/sdc

Disco /dev/sdc: 1014 MB, 1014644736 byte
8 heads, 32 sectors/track, 7741 cylinders
Units = cilindri of 256 * 512 = 131072 bytes
Disk identifier: 0x59c07261

Dispositivo Boot      Start         End      Blocks   Id  System
/dev/sdc1               1          76        9712   27  Sconosciuto
/dev/sdc2              77        3891      488320   83  Linux
syncron@syncron-laptop:~$

thanx 4 help!

If the cards are the same size, you could use the dd command:
dd if=/dev/sdc of=/dev/sdd
Though, if the sizes are different, this may involve more work. Or you could use fdisk and mkfs to create a partition and filesystem, then use the -a option to the cp command. Check out the man pages for this stuff for more details.

Hi and thanx for reply!
The size of the cards is the same (and the model is the same!)...the problem is that I have only one card reader and I can't make the copy directly care_reader to card_reader...some ideas?

...but if I use the command dd if=/dev/sdc of=/dev/sdd and the new card is unpartitioned...with this command I capy also the partition table...so..I have to do nothing in the new card?
