Jeltka stands for J(ust) e(enough) l(inux) t(o) k(exec) a(another). It's a tiny Linux small enough to fit inside a 2.88 MB floppy. Here it's embedded in a Chromebook ROM to install Linux without media over the internet.

To download a Chromebook ROM containing Jeltka, please visit and run the script. Only the C720, HP Chromebook 14, C710, and HP Pavilion Chromebook currently have Jeltka ROM's.

Instructions for use:
If you go into the SeaBIOS boot menu, you'll see there's a second option "ramdisk". Press 2 to start that. 

A few seconds later you'll see the Jeltka login prompt. Just type "root" and hit enter.

Type "ifconfig lo up" to bring up the loopback interface.

Then you need to edit the wireless config file "vi /etc/wpa_supplicant.conf" and change the ssid and passphrase to match your wireless network. "I" is insert, ESC comes out of INSERT mode, ":wq" saves and quits, ":q!" quits without save. If you bugger something up try pressing "u" to undo, or just quit without saving.

Next "wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf". Wait till it associates and then type "dhcpcd wlan0". Once dhcpcd finishes just confirm you have connectivity by pinging or something like that.

Then, run the NetbootCD script. "", and choose your distro.
