Set the BIOS Mode

The BIOS firmware supports both legacy BIOS and Unified Extensible Firmware Interface (UEFI); the default setting is Legacy. Some operating systems support both legacy BIOS and UEFI BIOS and some support legacy BIOS only. These are the options for setting the BIOS mode before installing the OS:

If the OS supports legacy BIOS only, you must make sure that BIOS is set to legacy mode before you do the OS installation.
If the OS supports both legacy BIOS and UEFI BIOS, you have the option of setting BIOS to either legacy mode or UEFI mode before you perform the OS installation.

Note - Upon initial release of the Sun Blade X6270 M2 server, the Oracle Solaris OS does not support UEFI BIOS. The most up-to-date information about the server hardware and software is available in the Sun Blade X3-2B (formerly Sun Blade X6270 M3) Product Notes.
