This Solaris release fully uses disks larger than 8 Gbytes because of improved BIOS interfaces. Previously, the following limitations impacted IA based systems running the Solaris Intel Platform Edition:
On IDE disks, only the first 8 Gbytes could be used by the system.
On either SCSI or IDE disks, only the first 8 Gbytes could only be used for the root (/) slice.
Both of these restrictions have been removed on systems with improved BIOSes.
See Solaris 8 (Intel Platform Edition) Installation Guide for more information.
