does anyone know the maximum user process size under xenix 3.0? i am using it on an AT and can only get about 1.2MB via mallocs. also, i assume that it would be very difficlut for me to change this limit without the sources (like any other un*x system), right? john kullmann decvax!sun!plx!jk

Check out those files, and the manual entries for 'CONFIG' and '/etc/master'. Basically, Xenix provides you with just enough source to tune your system, and to add in device drivers.

The files for such modifications are in places like "/sys/h" or "/sys/conf/xenixconf". (I'm not exacly sure right now.) It is possible to recompile the kernel, infact it is necessary if you install new periferals which XENIX has to know about. Hope this helps you. Mark Galassi ...!tektronix!reed!rosalia
