2. Connect the RXE-100 to the x450 as described in “Remote Expansion

4. Re-apply power to the RXE-100.
5. Power on the server. The enclosure will power on automatically as the server

Windows Server 2003 supports all 12 slots in the RXE-100.
Accessing EFI System Partition from Windows
To access the EFI System Partition from within operating system, use the
following utility.
mountvol DriveLetter: /s
Where DriveLetter is any spare drive letter in the system.
The ESP will be accessible for both read and write operations, although altering
its content is not recommended except, for example ,adding new firmware
updates to its root for later use with the Flash Update utility from within EFI.
Exporting and importing the operating system EFI boot record
During the installation process, the Setup program adds a new entry to the EFI
Boot Manager menu.
It will be added to the top of the menu so that if no keys are pressed once the EFI
Boot Manager menu appears, Windows will automatically start. The default delay
is 30 seconds and may be changed using the
Set Auto Boot Timeout
option in
the Boot option maintenance m
enu
.
The EFI Boot Manager records are stored in NVRAM (non-volatile RAM). If the
boot record is deleted from EFI NVRAM, there is no other way to start Windows
except for restoring the boot record from backups made using the NVRBOOT.EFI
utility.
Important:
Do not alter the content of EFI directory on the EFI System
Partition. As described in 1.3.2, “EFI System Partition” on page 8, this
directory contains the files necessary to boot installed operating systems.
Tip:
After Windows Server 2003 is installed, use NVRBOOT.EFI to export the
Windows boot record, then store the file in a safe location. If the system
partition gets corrupted, you can easily recreate it and then restore the
Windows boot record.
