Abstract:
A method for accessing a data image on a network adapter in response to receipt of a read address from a host computer at said network adapter, said method comprising the steps of:providing from said network adapter to said host computer a code size value identifying the memory size of a predetermined code image stored in a memory within said network adapter; receiving at said network adapter from said host computer a host base address; mapping said host base address to a base physical address that identifies a physical address location within memory on said network adapter; receiving at said network adapter said read address from said host computer and determining within said network adapter whether said read address is in a range between said host base address and the host base address plus said code size value; in the event said read address is within said range: determining an offset between said read address and said host base address; locating within said network adapter memory a target address specified by said base physical address plus said offset to identify a target memory location; transferring information stored at said target memory location to a buffer readable by said host computer.
