Booting From Partitions Greater Than 2 Gbytes (BugID 1234177)

Due to PROM limitations, no sun4d and sun4m architectures boot from partitions greater than 2 Gbytes. These systems fail with the following message:

bootblk: can"t find the boot program

All sun4u architectures support booting from larger partitions.

One related bug (4023466) reports a problem with re-preinstall where the boot image for large disks creates root partitions greater than 2 Gbytes. System administrators are cautioned not to use re-preinstall on sun4d or on sun4m systems with large root disks (4 Gbytes and greater).
