Abstract

A driver bundle including a compressed, executable and self-extracting host driver prepended to an adapter card driver to form a single executable driver bundle. The driver bundle has a size less than the maximum allowable size for a command file, which is 64 Kbytes as defined by MS-DOS®. The combined size of the expanded host driver and the adapter card driver is greater than the maximum allowable size. When the driver bundle is executed, it commands a processor of a computer system to expand and execute the host driver. The computer system includes a network adapter card with an adapter processor for executing the adapter card driver. When executed, the host driver commands the processor to retrieve and download the adapter card driver to the network adapter card for execution by the adapter processor.

Claims

1. A computer system, comprising:

a host memory for storing a driver bundle, said driver bundle including a compressed, self-extracting and executable host driver prepended to an adapter card driver;

a host processor coupled to said host memory for executing said driver bundle;

an expansion bus coupled to said host processor and said host memory; and

an adapter card coupled to said expansion bus, said adapter card comprising;

an adapter processor for executing said adapter card driver, and

adapter memory coupled to said adapter processor;

wherein said driver bundle, when executed by said host processor, commands said host processor to expand said compressed host driver within said host memory, to execute said expanded host driver, and to download said adapter card driver to said adapter memory of said adapter card.

2. The computer system of claim 1, further comprising:

a storage device coupled to said host processor for storing said driver bundle; and

wherein said host processor retrieves said driver bundle from said storage device, loads said driver bundle into said host memory and executes said driver bundle.

3. The computer system of claim 2, wherein said storage device comprises a floppy disk drive.

4. The computer system of claim 2, wherein said storage device comprises a hard disk drive.

5. The computer system of claim 2, wherein said storage device comprises a CD-ROM disk drive.

6. The computer system of claim 1, further comprising:

said adapter card being a network adapter card

a network coupled to said network adapter card, said network including a storage device for storing said driver bundle; and

said adapter memory including boot up code for initiating operation of said network adapter card;

wherein said adapter processor, upon power up, executes said boot up code, retrieves said driver bundle from said storage device of said network and provides said driver bundle to said host memory, and wherein said host processor executes said driver bundle from said host memory.

7. The computer system of claim 6, wherein said host memory includes a ramdisk portion and an executable portion.

8. The computer system of claim 1, wherein said driver bundle is a command file having a size less than 64 kilobytes, and wherein the combined size of said expanded host driver plus said adapter card driver is greater than 64 kilobytes.

9. The computer system of claim 1, wherein said adapter card is a network adapter card for enabling the computer system to communicate with a network.

10. A driver bundle for a host computer with an adapter card, the host computer including a host processor and the adapter card is logic, the driver bundle comprising:

a compressed, self-extracting and executable host driver for execution by the host processor, and

an adapter card driver, for execution by the processing logic of the adapter cord, appended to said compressed host driver to form a single executable driver bundle;

wherein said driver bundle has a size less than the maximum allowable size for a command file for execution by the host processor.

11. The driver bundle of claim 10, wherein said maximum allowable size is 64 kilobytes.

12. The driver bundle of claim 10, wherein said compressed host driver, when executed, includes commands for expanding itself into an executable host driver and to execute said expanded host driver, which host driver includes commands to download said adapter card driver from a storage device to the adapter card.

13. A method for providing drivers for a computer system and an adapter card, comprising the steps of:

compressing a host driver into a self-extracting, executable command file for execution by the computer system; and

appending an adapter card driver, for execution by processing logic on the adapter card, to the end of the compressed host driver forming a single driver bundle command file for execution by the computer system.

14. The method of claim 13, wherein the computer system includes a host processor and host memory for executing the driver bundle command file, and storage memory for storing the driver bundle command file, further comprising the steps of:

loading the driver bundle command file from the storage memory into the host memory;

executing the driver bundle command file;

extracting the host driver within the memory;

retrieving the adapter card driver from the storage device; and

downloading the adapter card driver to the adapter card.

15. The method of claim 14, wherein the adapter card is a network adapter card for enabling the computer system to communicate with a network, the network including a storage device for storing the driver bundle command file, prior to said step of loading the driver bundle command file from the storage memory into the host memory, further comprising the step of:

transferring the driver bundle command file from the storage device of the network to the storage memory of the computer system.

16. A computer system comprising:

a host memory;

an adapter card including processing logic;

a local storage that stores a driver bundle, the driver bundle including a compressed, self-extracting host driver and an adapter driver; and

a processor coupled to the host memory, the adapter card and the local storage, wherein the processor copies the driver bundle into host memory and executes the driver bundle, wherein the driver bundle instructs the processor to extract and execute the host driver within the host memory, and wherein the host driver instructs the processor to transfer the adapter driver from the local storage to the adapter card for execution by the processing logic of the adapter card.

17. The computer system of claim 16, wherein the host driver and the adapter driver are compatible to enable proper operation of the adapter card with the computer system.

18. The computer system of claim 16, wherein the local storage comprises a portion of the host memory.

19. The computer system of claim 16, further comprising:

a network coupled to the adapter card;

a network storage coupled to the network that stores the driver bundle; and

the adapter card retrieving the driver bundle from the network storage via the network and providing the driver bundle to the local storage.
