These two might be possible to flash in system:


Hardware Preparation

     Open the case
         You'll now have to disassemble your device (which most likely 
voids your warranty).
     Disable write protect
         You'll have to locate the Write Protect jumper and enable it.
         This will make the BIOS read-write so you can update it.
         Once things have been updated, you can undo this so your BIOS 
is read-only again.
     Reassemble the device
         Now that you've done toggled the jumper, you need to reassemble 
the device and power it up.
     Check the write protect
         Run crossystem and look at the wpsw_cur field; it should be 0.
     Plug your system in to be safe!
         For the Chromebook laptop, make sure the battery is charged, 
and the power supply is connected.
         For the Chromebox, try and plug it into a battery backup (UPS), 
and don't try this during a storm :).

Now what is with the other five?
Here it looks like information of chromium.org stops:

Do the other chromebook have  write protect jumper as well?
