[comp.unix.wizards] Increasing Syspt in Sun 3.4

budd@bu-cs.BU.EDU (Philip Budne) (01/06/88)

We kept finding that well configured systems under 3.4 would not boot
because the system page table was not large enough; Here is the
largest value of SYSPTSIZE that will not overflow the system segment.
More room might be gleaned by crowding the space allocated for kadb.

Alas you need sources.  Sun config will not allow "maxusers" to exceed
32, and we didn't get sources to config!!  I just edited the makefile.
