Abstract
Abstract A memory card drive which is compatible with MS-DOS computer systems as well as other computers which do not use MS-DOS as the operating system. The memory card drive comprises an embedded server which is a bridge between a client computer and a pair of memory cards allowing for communication and data transfer between the client computer and the memory cards. The server includes an ethernet interface which connects the server to ethernet bus which is connected to the client computer. The server has a memory card interface module which allows the client computer to communicate with the memory cards and thereby transfer data to the memory cards and retrieve data from the memory cards. The server also includes an embedded computer which enables and controls the functions and operation of the memory card interface and ethernet interface using a computer software program. The embedded computer has a two megabyte hard drive which has the computer software program stored therein.
