Finally, I could boot the samsung nc10 plus from the SD port in the front (the developper of the plop bootloader informed it should be ok).
This is a workaround but with that method, NO usb port is used and they can be used for an usb mouse, a card reader, an usb modem. The other advantage is: a SD card in the SD port dont take much place and dont much stick out of the netbook.
THANKS to plop. See

Method 1:
- make an usb stick with extlinux or syslinux on it
- make a submenue of extlinux of that usb for starting the plop bootloader
- setup the bios of the netbook for starting from the usb
- put the usb in an usb port
- put the SD card (with a bootloader on it and an operating system) in the front port of the netbook
- switch on the netbook
- when the prompt appear in the extlinux bootmenue, choose the plop boot loader
- when plop is started, choose the usb submenue of plop
- then the SD card and its operating system on it (start with extlinux) will be launched
- dismount later the usb stick where plop is
.. no usb is used!
Perhaps it runs with plop installed on the hdd; I did not try. But there is no reason this would not run.
Method 2:
- install plop and tinycorelinux on a SD card (parallel boot with extlinux)
- put that card on an usb adapter (I have the luck to have a card adapter from TCHIBO in Germany which is recognized by all BIOS until now).
- start the netbook from the USB adapter (and the card on it)
- start plop from the SD card (it is on the screen)
- take the card away from the usb adapter and put it into the SD port in the front of the netbook
- choose the usb menu of plop (still on the screen)
- it boot then automatically into the SD card
- choose TinyCoreLinux (not plop.. or other OS you will have on that card)..
and it boots.

try this to see if plop can redirect to another
usb or SD port for freeing the USB adapter
in case the SD is on it
