Recovering from a BIOS update failure
To recover from a BIOS update failure, do the following:
1. Prepare your computer. See "Preparing your computer and removing the computer cover" on page 57.
2. Locate the Clear CMOS /Recovery jumper on the system board. See "Hardware locations" on page 1.
3. Remove any parts and cables that impede your access to the Clear CMOS /Recovery jumper.
4. Move the jumper from the standard position (pin 1 and pin 2) to the maintenance position (pin 2 and
pin 3).
5. Reinstall the parts and cables that were removed.
6. Reinstall the computer cover and reconnect any cables that were disconnected. See Chapter 7
"Installing or replacing hardware" on page 57.
7. Turn on the computer and insert the BIOS update disc into the optical drive. Wait a few minutes. The
recovery process begins. After the recovery process is completed, your computer will shut down
automatically.
Note: If the computer does not start up from the disc, select the disc as the startup device. See
"Selecting a temporary startup device" on page 37.
8. Repeat steps 1–4.
9. Move the Clear CMOS /Recovery jumper back to the standard position (pin 1 and pin 2).
10. Repeat step 6 and step 7. Then, turn on your computer.
Configuring RAID
This chapter provides instructions on how to install hard disk drives and configure RAID for your computer.
Depending on your computer model, RAID can be enabled by Intel Rapid Storage Technology enterprise
(RSTe) or the LSI MegaRAID BIOS.
Note: The RAID configuration information described in this chapter is only applicable in the Windows
environment. For information about configuring RAID in the Linux
software provider.
This chapter provides information about the following topics:
•
"Configuring RAID with Intel RSTe" on page 39
• "Quick RAID setup using the LSI MegaRAID BIOS configuration utility " on page 41
Configuring RAID with Intel RSTe
If your computer comes with Intel RSTe, you can follow the sections below to configure RAID with Intel RSTe.
This section provides information about the following topics:
•
"Installing SATA or SAS hard disk drives" on page 39
• "Configuring SATA or SAS RAID functionality with the Intel RSTe configuration utility" on page 40
Installing SATA or SAS hard disk drives
Ensure that your computer has the minimum number of SATA or SAS hard disk drives installed for the
following supported levels of RAID:
• RAID Level 0 - Striped disk array
– A RAID Level 0 hard disk drive group consisting of at least two hard disk drives
– Supported strip size: 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB
– Better performance without fault tolerance
