If SolarisTM Web Start 3.0 is unable to locate a Solaris fdisk partition on a system, you must create a Solaris fdisk partition on your root disk.
If you change the size of an existing fdisk partition, all data on that partition is automatically deleted. Back up your data before you create a Solaris fdisk partition.
Solaris Web Start requires two fdisk partitions to perform an installation.
Solaris fdisk partition
This is the typical Solaris fdisk partition.
x86 Boot fdisk partition
This is a 10 MByte fdisk partition that enables Intel Architecure to boot the miniroot that is placed on the newly created swap slice located on the Solaris fdisk partition.
The Web Start installation utility creates the x86 boot partition, taking away 10 MBytes from the Solaris fdisk partition. This prevents any existing fdisk partitions from being altered.
This partition should not be created manually.
This requirement also prevents you from upgrading the Solaris 2.6 or Solaris 7 releases to the Solaris 8 operating environment using the Solaris 8 Install CD. For more information refer to "Upgrade Issues".
