Puppeee was created by jemimah specifically for the asus eeepc 700 series, the build will work happily on the 900/ 901s also.
It is slightly larger than Puppy, at 138 MB, but still smaller than many alternatives, such as eeeXubuntu, while still having matter which way you decide to go, you have to download an ISO image of the latest Puppeee release and use a machine with a CD/ DVD burner to burn a Puppeee CD. You can then use it to create a bootable Puppeee USB stick or SD card. To boot your Eee PC into Puppeee, turn the laptop on, press the Esc key when the boot splash screen appears, and select the device containing Puppeee.
Puppeee Driver for Windows 7 32 bit, Windows 7 64 bit, Windows 10, 8, XP.
