This paper describes the theory and method of programming under the environment of UEFI Shell and also introduces the UDK2010.UP4 install and configuration. The program run in UEFI Shell can get EFI Boot Services through the EFI_SYSTEM_TABLE parameter, after this it can operate disk files through Simple File System Protocol and EFI File Protocol. The work in this paper mainly introduces some file operations in UEFI Shell, such as file creating, data access on a FAT file system disk through a UEFI Application (UEFI App hereafter).

Disk Caching

XRootD† has been established as a standard for WAN data access in HEP and HENP. Site specific features, like those existing at GSI, have historically been hard to implement with native methods. XRootD allows a custom replacement of basic functionality for native XRootD functions through the use of plug-ins. XRootD clients allow this since version 4.0. In this contribution, our XRootD based developments motivated by the use in the current ALICE Tier 2 Centre at GSI and the upcoming ALICE Analysis Facility will be shown. Among other things, an XRootD redirector plug-in which redirects local clients directly to a shared file system, as well as the needed changes to the XRootD base code, which are publicly available since XRootD version 4.8.0, will be presented. Furthermore, a prototype for an XRootD based disk caching system for opportunistic resources has been developed.
