摘要： A method and apparatus for increasing system functionality through a predefined interface is disclosed. Signal lines which are not used or which are not used in certain modes are connected to an interconnection device instead of being connected to an interface wherein the output of the interconnection device is connected to the interface where such lines would have been connected. The interconnection device also has a set of inputs for receiving signals from a device providing the desired functionality. A controller chooses between the two sets of inputs to control what signal lines are connected to the predefined interface. Accordingly, during certain modes of operation, the added functionality from a device whose output is being switched into the interface can be supported. In one embodiment, speaker phone capability is provided for even though the predefined PCMCIA interface does not support such capability. The disclosed design continues to maintain capability with all systems adapted to be used with such predefined interface.

摘要： A method for hot docking and hot undocking a portable computer and a docking station. The portable computer and docking station are physically coupled via a shared PCI bus and an expansion connector. Varying length pins in the expansion connector generate docking and undocking handshaking signals used by microcontrollers in the portable computer and docking station. The portable computer and docking station are functionally connected via low on-resistance switches located in the portable computer. Following a docking event, closure of the switches connects the portion of the shared PCI bus in the docking station with the PCI bus in the portable computer. When the switches are open, the PCI busses are functionally isolated. Both the portable computer and the docking station also include a local arbiter for arbitrating and granting bus control requests from devices coupled to the shared PCI bus. These local arbiters may be placed into an idled state by either the operating system (through system BIOS) or by the microcontrollers. The arbiters are idled during docking and undocking events in order to inhibit bus cycles on the PCI bus, thereby preventing cycles from being lost. Following completion of a hot docking or undocking event, Plug-and-Play system reconfiguration is carried out so that all system resources may be recognized and properly utilized by the operating system.

摘要： In accordance with the invention, a computer system is provided with a processor, a flash ROM, a microcontroller and an arbiter for selectively assigning the ownership of the flash ROM to either the microprocessor or the microcontroller. The arbiter assigns the flash ROM initially to the microcontroller when it boots up. After checking the integrity of the flash ROM and updating the content of the flash ROM with valid software if necessary, the microcontroller releases the flash ROM to the microprocessor to enable the computer system to proceed with the normal boot-up process. In this process, various system self tests are performed. Next, the microprocessor shadows one or more portions of the flash ROM BIOS into a main memory array. After the processor successfully boots up, the processor releases the flash ROM back to the microcontroller by writing a command to a mailbox register in the arbiter which places the microcontroller in an idle mode and by restarting the clock generator of the microcontroller. The restarting of the clock signal to the microcontroller to switch the ownership of the flash ROM back to the microcontroller. In the event that the microprocessor needs to regain access to the flash ROM contents, the microprocessor writes to the mailbox register of the arbiter to request access to the flash ROM. The microprocessor waits for a confirmation from the arbiter that the microcontroller is entering an idled mode. Next, the microprocessor halts the clock of the microcontroller. These events cause the microcontroller to float or tristate the signal lines going from the microcontroller to the flash ROM such that the microprocessor can drive the signal lines without any conflict potentials. In this manner, the microprocessor can still access the shared flash ROM after it has booted up. Thus, the system cost is reduced, the system reliability is enhanced, while the system accessibility to the flash ROM after the boot-up period is still preserved.

摘要： A computer system having a processor, a microcontroller, a flash ROM is provided with an address remapper for handling warm-boot events, and an arbiter for selectively assigning the ownership of the flash ROM to either the microprocessor or the microcontroller. The arbiter assigns the flash ROM initially to the microcontroller when power is initially provided to the system. After the flash ROM boots up and checks the integrity of the flash ROM and updates the content of the flash ROM with valid firmware if necessary, the microcontroller releases the flash ROM to the microprocessor to enable the computer system to proceed with the normal boot-up process. In this process, various system self tests are performed. Next, the microprocessor copies or shadows one or more portions of the flash ROM BIOS into a main memory array. After the shadow operation, the processor sets a remap bit to indicate that the ROM BIOS content has been copied into the main memory array. The setting of the remap bit enables the remapper to deflect accesses to the flash ROM.
