  Disk Image Creation and Transfer Mechanism for Remotely Booting From a Diskette

Disclosed is a mechanism for transferring the contents of a diskette to a server using a web browser.

The problem is providing a system administrator the ability to remotely boot a server from a diskette, which may be done for diagnostic or recovery purposes. The technical challenge is to make remote booting from a diskette as straightforward as booting from a diskette would be if the administrator were seated at the server console. An image of the diskette must be created and transferred to the server while hiding the details of the process from the administrator. The only application at the administrator's disposal is a web browser, which is his interface to the service processor on the server.

The steps required to transfer the complete contents of a diskette are well beyond the capabilities of a standard Java* enabled web browser alone. The solution is to use a combination of a signed Java applet and a variety of disk imaging utilities that are either supplied by the operating system or downloaded from the web server without intervention from the administrator. The service processor's web server is used as the transmission mechanism. The service processor stores the diskette image on the

server and instructs the BIOS to use it to emulate a diskette after transmission is complete.

From the administrator's vantage point, the process appears to be simple: He inserts a diskette in his own diskette drive, and the server boots from it. However, there are technical hurdles that are overcome out of the administrator's view in order to transfer the diskette image to the server:

1. A bootable diskette contains a boot sector as well as a number of files that are used for booting. A Java applet cannot do a low-le...
