Hello,

Was thinking about throwing a new drive in my SS20 to try NetBSD 4 or
5.  Was wondering if anyone is using my config (or close) could give
me a general idea of the end result.  My system has 2 x 200Mhz ROSS
processors (RT626) or I can put in 2 x SM81. I also have 448mb RAM and
CG-14 with 8mb VSIMM.

cg14 works fine bu SMP is currently broken.

Some window managers and applications crash the CG-14 driver.  For
example many Gnome 2.x apps and many window managers like Windowmaker,
XFCE, etc. also crash X11.  CDE, fvwm, fluxbox, blackbox, and
openwindows are the only ones I've ever been able to run with any
stability with the CG-14.  This is with the 2002 Sol9 release and the
latest recommended patch cluster applied.  The instability in X is my
only sadness with this machine.

NetBSD's Xserver can use the cg14 as a dumb framebuffer with a hardware cursor. The only occasional problem is that some applications are dumb enough to always expect an ARGB visual while the cg14, like most Sun graphics hardware, is ABGR. THey are few and far between though and all you'd see is wrong colours, no crashes.

So can anyone tell me what sort of system can be achieved with the
later incarnations of NetBSD?  I see there is a non-accelerated cg14
driver.  Anyone use it and can you appraise the performance compared
to the Solaris driver in 24 bit X?

Slower, but not much. The SX doesn' seem to be all that fast. Unfortunately documentation doesn't seem to exist anymore :/

I also see the SMP is available now on the SS20.  Is that hard to get
working and does it perform well?  Can it be used with the 4.x release
or is it a 5.0 only feature?

It should work in 4.x but got broken between 4.x and 5.x, a fix is on the way but it's not there yet.

I'm not a developer, but I have a long history using the gcc tool chain to compile packages, resolve dependencies and what not. It's a lot of work I understand, but if the end result is worth it, I'm probably willing to give it a try.

pkgsrc takes care of most of that ( and it works on Solaris too )

have fun
Michael
