[OpenIndiana-discuss] How should a disk partition layout looks like

[Carsten Grzemba]

I have a disk installed with Openindiana and installboot shows bootloader at cxt0d0s1 and has not cxt0d0p1
The disk will not recognized by BIOS for boot but it boots if selected in loader.

On other resources shows EFI boot files on cxt0d0p1.

Is p1 partition necessary for boot?
How looks like a correct disk partitioning nowadys?

Thanks!
