Locate the DVD/CD drive When hardware (for example, HDD, a USB device, or a DVD-ROM drive) is added to a system after it has booted to EFI, the EFI Shell environment does not automatically detect the new device. You must reconnect the device driver for the EFI Shell to recognize the device. The EFI Shell environment creates default mappings for all the device handles that support a recognized file system. After you change the system configuration or add a new device, you must regenerate these mappings. To enable the EFI Shell to detect and access the DVD/CD drive, complete the following steps: 1. From the EFI Shell, enter the reconnect -r command. The reconnect command reconnects one or more drivers from a device, disconnecting all the drivers from all the devices and then reconnecting them. If you do not specify a device handle, the reconnect operation is performed on all the handles in the system. If you do specify a device handle, only the device handle and the devices below it are reconnected. 2. From the EFI Shell, enter the map -r command. The -r option regenerates all the mappings in a system. The EFI Shell displays the device mapping table, as follows. fs0 : Acpi(PNP0A03,0)/Pci(2|0)/Ata(Primary,Master)/CDROM(Entry1) blk0 : Acpi(PNP0A03,1)/Pci(1|0)/Scsi(Pun0,Lun0) blk1 : Acpi(PNP0A03,0)/Pci(2|0)/Ata(Primary,Master) blk2 : Acpi(PNP0A03,0)/Pci(2|0)/Ata(Primary,Master)/CDROM(Entry1 3. Note the device name of the CD device: fs0 You use this to explore the contents of the CD or DVD. The map command displays or defines a mapping between a user-defined name and a device handle. The most common use of this command is to assign drive letters to device handles that support a file system protocol. When these mappings are created, the drive letters can be used with all the file manipulation commands. Use the map command to create new mappings or delete an existing mapping with the -d option. If you use the map command without any parameters, all the current mappings are listed. If you use the -v option, the mappings are shown with additional information on each mapped handle. The following table describes the device mapping fields. Table 1-4 EFI device mapping fields Item Description blkn This indicates a physical drive or a partition on a physical drive. A physical drive can be a hard disk drive or a removable media drive. A Partn (in parentheses) appears when a disk drive contains a partition. Acpi(Device,X) Acpi is Advance Configuration and Power Interface. The device type is the first entry in parentheses. The second entry, X, is the PCI host number. Pci(D/F) This indicates PCI-related information. D is the PCI device/slot number and F is the PCI function number. Scsi(Pun.Lun) This denotes the physical characteristic of the SCSI disk. Pun is the SCSI number and Lun is the LUN number on the physical device. HD(Part,Sig) This indicates the partition Part and EFI signature Sig on the partition. Preparing the server hardware 31
