In response to a question posted some few days ago regarding ESIX on
Gateway 2000 386-20 systems, yes it seems to work. At present the
system has a Seagate 4096 drive and 4MB of memory. (I am using Xterm
to cu to my news system to write this). Next mod is to upgrade to
some decent disk space!
One glitch that I do not understand, but will pass on: The tunable
parameter DMAEXCL does significantly improve performance. (wish i
knew more accurately how to set the parms, but the sample on pg 5-32
is infinitely better than the distributed version) CAUTION: the
rebuild after changing this hosed my X-Windows install. DE-installing
X-win and TCP/IP and then RE-installing made it fly again. I would
recommend doing the tune before installing much more than the basic
utils disk to avoid this possible glitch.
I have installed (and will soon test) the Rabbit Software X.25 gateway
on this system. Install was painless, hope to make it all work.

I have an esix system rev D that I would like to tune up for 8meg of memory and an SCSI controller. Other than the default tuning parameters that get changed when you install the packages, what other tuning parameters can improve performance. For example, I have a problem that some software running on my machine has caused fatal error 11 to occur. This sometimes happens when running the C compiler or the Meridian Ada compiler (which is nothing more than an Ada to C translator). It happens when I am running through a tcp/ip port usually running mwm and several xterms (although I have an Xwindows terminal that acts as the server). Since I have been afraid due to ignorance to touch the tuning parameters (except for maxumem which is set to 8092), some advice from those who have gone before will be much appreciated. I am running on an HPVectra RS20C with 8 meg of memory (including the low memory) a vga and both an ESDI disk (300 meg) and two SCSI disks (300 and 600 meg). Thanks for the advice.
