Micro personal digital assistant with a compressed BIOS system

Abstract

A personal digital assistant module with a local CPU, memory, and I/O interface has a host interface comprising a bus connected to the local CPU and a connector at a surface of the personal digital assistant for interfacing to a bus connector of a host general-purpose computer, providing direct bus communication between the personal digital assistant and the host general-purpose computer. In an embodiment, the personal digital assistant also has a means for storing a security code. The personal digital assistant according to the invention forms a host/satellite combination with a host computer having a docking bay, wherein upon docking a docking protocol controls access by the host to memory of the personal digital assistant based on one or more passwords provided by a user to the host. In another embodiment the personal digital assistant has a compressed BIOS chip, and in yet another embodiment also has an expansion port connected to the local CPU, and expansion peripheral devices may be connected and operated through the expansion port.

Problems solved by technology

Given the new systems now introduced, and those coming, for what is now known about them, there are still a number of drawbacks and problems.

The PDA systems introduced are relatively costly, with starting prices ranging from several hundred dollars to two thousand dollars and more.

At such prices, rivaling current pricing for desktop systems, the buying public may react negatively.

It is true that prices will fall with increased manufacturing volume and competition, but the high end start may well be rejected by potential users.

The systems being offered are still relatively bulky, considering the limited range of tasks that may be accomplished.

Most are certainly too big to be conveniently carried in a breast pocket.

A big drawback of the PDA systems being offered is the way they transfer data between a user's desktop unit, or other host, and the PDA.

These all require manipulation by a user, modulation on one or both ends of the communication path, and the like, which can be time-consuming, error-prone, and hardware extensive (ex
