Excerpt
Excerpt The concepts used in zSeries SCSI IPL significantly enhance the capabilities of IPL, as described above. By using an arbitrarily complex machine loader and loading it into the machine from the SE to control the IPL process—instead of using a routine that is stored in read-only storage—the IPL routine can be upgraded more easily. Since the machine loader can be arbitrarily complex, it can fully utilize all of the capabilities of the machine, and it can support a wide range of boot devices at any address in an FC SAN. The zSeries SCSI IPL process also supports simultaneous execution in multiple logical partitions or z/VM guests. Details of how these new concepts were applied to SCSI IPL, along with a variation of SCSI IPL that dumps the contents of program memory to a SCSI disk, are provided below.

Claims
1
A method of delivering a device driver to an operating system executing on a computer platform, the method comprising:
during booting of the operating system, identifying a first device for which a device driver is needed;
requesting the device driver from a service processor installed on the computer platform, wherein the service processor comprises a storage configured to store one or more device drivers; and
delivering the device driver to the operating system without intervention by a user.
