Chapter 3. Installing an operating system in legacy mode
This chapter provides information about installing operating systems in legacy mode.
Before installing an operating system in legacy mode
This topic contains the following items:
• “Preparing the driver” on page 59
• “Configuring the BIOS setting” on page 59
Preparing the driver
Before installing an operating system in legacy mode, download your desired driver from the Lenovo Web
site at
http://www.lenovo.com/drivers. Then, copy the driver to a USB storage device.
If the operating system is installed on a storage area network (SAN), download the driver for the host bus
adapter (HBA) or converged network adapter (CNA) that is connected to the SAN. Then, copy the driver to a
USB storage device.
Notes:
• You can load driver files using a USB storage device or a disc. The steps in this document are based on
the scenario that you use a USB storage device to load driver files. If the USB storage device fails to load
driver files, try using a disc. If you are installing an SUSE operating system, your are advised to use a disc
to load .iso driver files.
• Depending on the configuration, you might install the operating system on a SAN or a hard disk drive. For
Microsoft Windows operating systems, the two installation procedures are the same.
• Set the optical drive that you want to use as the first startup device. Depending on the server model, an
external optical drive might be required.
Configuring the BIOS setting
Before installing an operating system in legacy mode, configure the BIOS setting by doing the following:
1. Start the Setup Utility program.
2. On the Boot Manager menu, select Miscellaneous Boot Settings and press Enter.
3. On the Storage OpROM policy menu, select Legacy only.
