The EFI Shell environment creates default mappings for 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 drivers from a device, disconnecting drivers from all devices and then reconnecting them. If you do not specify a device handle, the reconnect operation is performed on all handles in the system. If you 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 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 (in the above example): 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 file manipulation commands. Use the map command to create or to delete mappings with the -d option. If you use the map command without parameters, all 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 is a block device that indicates a physical drive or a partition on a physical drive.

The EFI Shell environment creates default mappings for 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 drivers from a device, disconnecting drivers from
all devices and then reconnecting them. If you do not specify a device handle, the reconnect
operation is performed on all handles in the system. If you 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 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 (in the above example):
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 file manipulation commands.
Use the
map
command to create or to delete mappings with the
-d
option. If you use the
map
command without parameters, all 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.

Set ACPI Flag to Windows (Cell-Based Servers Only)
On cell-based servers, you must set the Advanced Configuration and Power Interface (ACPI)
flag to the value relevant for the OS it boots. For the server to boot to Windows Server 2008, set
the ACPI flag to
windows
