Re: S3 Trio64 support



Dear Gary

The S3 cards do work perfectly in an Alpha under Debian. If I remember right, the S3 needs RAMDAC support and needed an XFree86 v3.x. I don't know wether the latest Xorg or XFree86 supports this, it seems not... (BTW: Have disabled graphical login? If not -> comment out the login manager in /etc/X11/default-display-manager). Anyway how it works:

You can install both versions of 4.x and 3.x of XFree86. Don't ask me why nor how, fact is X runs in the end on your S3:

Install xserver-s3 xserver-common-v3 and xserver-xfree86. I don't know if this works with xorg. The packages are in woody? You may find them in snapshot.debian.net or, hmm, recompile. Anyway it's a security risk, because these packages aren't supported anymore.

Some AlphaServer are quite picky with their video card. Generally S3 is a good choice and there are such cards which do run in Xorg without that old stuff. IIRC Elsa Winner was one.

Regards, Adrian.

I have a Personal Workstation 433au with an S3  86c764/765 (Trio
32/64/64+) graphics card in it. This works with Windows and with
OpenVMS just fine. I assume it was working with Tru64 UNIX as well, as
that is what was installed when I obtained this box.

However, I can't find a suitable X driver or configuration to get this
card to work even at plain VGA levels with Alpha Linux. Logically, the
s3 driver should do the trick but no matter what I try, it doesn't
activate the card. DEC did sell a lot of these with that card in them,
I believe, and it seems as if we must have support for it buried
somewhere. However, even the man page for the s3 driver is missing
from the current distribution, though the driver is still included.

I could actually live without X on this machine, since it works well
enough as a client to other machines. However, I really would like to
at least have a shell interface from the console, and even that does
not work. Booting from SRM (which finds the keyboard and video card
without difficulty) I do get the bootup messages right up to the point
at which Apache loads. I think this is part of init level 3. Then the
display stops updating, and the keyboard is unresponsive.

The system finishes booting and can be reached via ssh from another
node, though. What do I have to do to keep the attached keyboard and
monitor working?
