Subject: MAXIMUM PROCESS SIZE under SCO UNIX ODT 1.1 and ANY OTHER 386 UNIX??

Do I understand correctly that the maximum user process size available
in SCO UNIX SYSV/386 is 4 MB (MAXUMEM=8,192 pages * 512 bytes/page)???

Is this limitation specific to SCO UNIX or is it generic to AT&T UNIX?

Can I get around this limitation by running under root, odt, whatever?

This is creating a serious problem for me as I move into working with
larger and larger 3D models of human brain structure and activity.

Does any other 386 based UNIX (or at least 386based system capable of
supporting AT&T and/or BSD compatible unix source code with minimal 
conversion effort) offer larger user process (individual task) virtual 
address space?  Perhaps BSD/386, 386BSD-0.1, coherent, solaris, linux,
MSDOS w/DJGCC, MS WINDOWS w/32 Bit Zortech C++, OS/2 2.0, ?

Ideally, I'd like to be able to go up to perhaps 64MB virtual address 
space on 64MB 486 based EISA motherboard.

Thanks, AJ
