Yes, I saw that in dklabel.h and was looking in various places for all
references to the _SUNOS_VTOC_8 or 16.

I thought that this was kinda funny in fmthard.c :
#if defined(_SUNOS_VTOC_16)
/* make the vtoc look sane - ha ha */
vtoc->v_version = V_VERSION;
vtoc->v_sanity = VTOC_SANE;
vtoc->v_nparts = V_NUMPAR;
.
.
.
and have been reading more on the issue of EFI labels.

and stick with netboot for the time being. check.
