The interface card-type motherboard can be directly plugged to the original motherboard of a computer so as to upgrade the computer, whereby the computer can execute new software and connect with new peripheral devices.

Abstract: A CPU escalating adapter with multivoltage and multiple frequency selection which is adapted for an escalated CPU is disclosed. The CPU escalating adapter comprises a circuit board, a power connection, a voltage regulator, a stabilivolt integrated circuit, a programmable array logic (PAL) and a toggle switch member. The cooperation of the toggle switch member and the voltage regulator forms a multiple voltage switching and a plurality of switches of the toggle switch member forms a selecting range between 2 and 5.5 of the frequency multiplication factor of the CPU.
