Starting with the Solaris 10 3/05 release, a new feature in the Solaris installation program is a boot-disk partition layout. This layout, by default, accommodates the Service partition on Sun x86 based systems. This installation program enables you to preserve an existing Service partition.
The new default includes the following partitions.
First partition – Service partition (existing size on system)
Second partition – x86 boot partition (approximately 11 Mbytes)
Third partition – Solaris Operating System partition (remaining space on the boot disk)
If you want to use this default layout, select Default when the Solaris installation program asks you to choose a boot-disk layout.
If you install the Solaris OS for x86 based systems on a system that does not currently include a Service partition, the Solaris installation program does not create a new Service partition. If you want to create a Service partition on your system, first use your system's diagnostic CD to create the Service partition. After the Service partition is created, then install the Solaris Operating System.
For information about how to create the Service partition, see your hardware documentation.
