I actually cleaned it really a lot because it was full of dust.
How do I make a reseat of the memory ??
I did not found any useful SRM utility instead on the VAXstation there is
a cool PROM utility to test memory (test mem).
I have a good experience of NetBSD/VAX but I do not have experience of
FreeBSD/alpha, I have just been looking around for a good OS for my
AlphaStation and excluding Linux at priori I have tryed NetBSD/alpha first
and then I Switched to FreeBSD/alpha. I have not even tryed OpenBSD/alpha
they don't even support ELF and LKM and shared libraries.
Anyway my big problem for now is really the Xfree86 I am unable to make it
work. And everytime I try to launch X it makes the kernel crash, the system
complitely hangs and I have to manual power cycle it.
I was thinking to mount the AlphaStation PCI card on a PC, configure it
there and compy back on my AlphaStation the XF86Config file.
My big problem is that XF86Setup does not work because it requres
XF86_VGA16 which is not included in the XF86336 distribution on the CDROM!!
I even tried to rebuild the Xfree86 compiling from the source tree but I
do not know why XF86_VGA16 is not built!

thanks

Rick
