  • Apparatus and method for interfacing a peripheral device having a ROM BIOS to a PCI bus
    Patent number: 5835960
    Abstract: An apparatus and method for providing a conversion technique to allow an eight bit ROM BIOS to be read on a 32 bit PCI bus. A separate address port for the ROM BIOS is provided which is not connected to the PCI bus. The conversion bus takes data from the ROM BIOS at a separate data port, assembles four cycles of eight bits in a 32 bit fashion and delivers that data to the PCI bus. When the PCI bus requests 4 bytes, the system of the present invention assembles 4 bytes from the 8 bit data and transmits that data to the PCI bus as a 32 bit quantity.
