All fixed disks, CD-ROM drives, and USB storage devices will appear as block devices. If the server contains additional controllers and disks, they will appear as additional block devices. The EFI automatically maps known file systems on the block devices to their FSx mappings (FSx is referred to as the file system identifier). Here are some tips for easier identification of devices in the list: Even with no storage devices, the server has at least two default mappings, the MemMap entries listed as fs0: and fs1: in Figure 4-3. These are read-only RAM disks created during POST, so they will always be available. The first MemMap file system is the content of the 4 MB of NVRAM assigned to the EFI and contains a number of drivers. The second MemMap file system is the content of the NVRAM assigned to the server diagnostics. 96 IBM xSeries 455 Planning and Installation Guide Eserver
