How to install linux on the libretto?

It is possible to install Linux or OpenBSD on these computers; the Handbook 486 is probably the earliest Linux-compatible subnotebook released. It is even possible to run the X windows system after the memory is expanded. The Handbook 486 has a PCMCIA II interface. While Modern Cardbus cards do not work with this interface, most older PCMCIA II cards (as long as they use no more than 250 mA of power ) work fine. The Handbook 486 also has a pointing device similar to the IBM trackpoint located on the right hand side of the keyboard just above the enter key.
