Embodiment Construction
[0030] Preferred embodiments of the present invention are described in detail below.
[0031] The realization method of network virtual disk of the present invention, it comprises concrete steps as follows:
[0032] 1. The client PCIROM intercepts the interrupt INT13 to generate a virtual disk, and sends the sector read and write request to the server by directly operating the network card hardware. The server network card ID number is obtained from the local network card EEPROM;
[0033] 2. The server PCIROM first obtains its working mode through a serial port switch group and reflects its working state. Then directly operate the network card hardware to read the client's request, and call the INT13 of the motherboard BIOS to access the public disk and private disk according to the request, so as to complete the client's request. Finally, the result is sent to the client by directly operating the network card hardware;
[0034] 3 The server has two hard disks, which are di...
