In the Solaris 9 (x86 Platform Edition) operating environment, the Solaris Web Start and suninstall installation programs use a new default boot-disk partition layout to accommodate the Service partition. If your system currently includes a Service partition, the new default boot-disk partition layout enables you to preserve this partition.
If you install the Solaris 9 (x86 Platform Edition) operating environment on a system that does not currently include a Service partition, the installation program does not create a new Service partition by default. If you want to create a Service partition on your system, see your hardware documentation.
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 environment partition (remaining space on the boot disk)
If you want to use this default layout, select Default when the installation program asks you to choose a boot-disk layout.
