I remember it being described as a "capacitance issue".
There is some text describing some of the limitations in
the old "Sun Framebuffer FAQ" document that is floating
around at various FAQ sites.  A recent (I think) copy
is here:

http://bul.eecs.umich.edu/~crowej/sunfaq/FrameBuffer.html

In particular, the "What frame buffers are/are not
support in the Ultra machines?" question is relevant.

They just don't work.

Empirical testing says they don't fry, either.

NetBooting problem

Hi all,

My name is Laurent, and I'm new to this ML. I'm
french, so I must appologies for my bad english ;-D

I've just got a Sparc Server 5 w/o any CD-ROM or
floppy disk, so i'm trying to install NetBSD by the
netboot methode.

The server machine is my Ultra 5 Sun workstation under
Solaris 8. This machine has 2 ethernet interfaces :
- hme0 connected to the internet (cable modem)
- hme1 connected to my own network
It act also as a DHCP server for this second network.

The Ultra's name is 'Zeus' and SS5 will be 'ra', with
the IP adress 192.168.0.3 ;-D
Everything is working fine on my own network as I can
connect on my Ultra from my others machines (Amiga,
VAX, PC, ...)

As explanned in the documentation, I have :

- installed sun-rbootd-1.3.2.tar.gz

- in /tftpboot, I have liked 
ln -s boot.net C0A80003.SUN4M

- in /export/home/client/root, I have unziped
netbsd.GENERIC and ungtared rootfs.tgz

   the test development branch is called sommerfeld_i386mp.  the i386 in
   the name is quite significant.  there is no SMP development branch for
   sparc.  all the -current (and probably netbsd-1-6) does is to spin up

well...  that's all it does by default.  but there's this #if 0 in
locore.s you can enable and it will attempt to run the other cpus
and blow up.  it *should* work but i haven't figured out why it blows
up yet (and haven't tried for a long time either, :-( )

   the second cpu.  that's all.  you may want to check the following url to
   compare various ports' status on SMP, etc. :

Re: cg6 from an ss2 to ss5, ok?


Folks, guess what:(,

this could be coincidence but the ss5 appears to have
fried the cg6.  It was a sunGX frame buffer : 501 1672.

It ran most of the day no problem. Then I went out
of the room, came back and the whole machine was
down. Took me 15 minutes of pulling things apart
to try and work out why it wouldn't even boot any
more!   When the cg6 was removed it booted. The
centre of the main SunGX  chip is a bit browned
and trying to boot with it I noticed it was very hot.
/var/log/messages reported:  (i assume relevant)
Sep  1 19:20:18 lewy /netbsd: NMI: system interrupts:
40000000<VME=0,SBUS=0,ME>
Sep  1 19:20:18 lewy /netbsd: trap type 0x29: pc=0x196b0
npc=0x196b4 psr=4400086<S>
Sep  1 20:24:52 lewy syslogd: restart

I've got a cg3 (my last card!) in it at present and all
is going again.

The cg6 sat in my old ss2 for years with no problem
and then 1 day in the new ss5 and kaboom.

1. It could be just a coincidence that it was about to
go. At the end of it's life etc. What do you think?

2. Or it was the : "arcane incompatibility".

Oh, that does not sound good.

First thing I would do is get out a vacuum and vacuum out all the dust
grilles.  Sounds as though cooling was insufficient, which to me says
that either fans have gone out or things are clogged with dust.  If the
machine hasn't been vacuumed out in the last year or two, my money
would be on dust.

That's one reason I suspect cooling.

Re: scsi id trouble

Your SS5 will set the ID of the SCA drives.  Further, Sun is a little
backwards in that the first drive is SCSI ID 3, and the second is 
ID 1. 

The lower bay is your boot drive, and that will get ID 3.  The upper
bay is ID 1.

The disk order is 3 1 2 0.  That pretty well makes no sense any more,
and I can't even remember the historical reason it was that way any more.
Some Sun FAQ probably has details on it.

I have my NetBSD kernel built to honor the PROMs disk order, as it causes
less grief than trying to fight it.

FilesSystem managment (stupid question)

Hi all,

before doing the final install of NetBSD on my SS5, I
wonder if I can enlarge or reduce the size of a file
system "on the fly", like using "vgexpand" on a HP-UX
box ?

Thanks

Lolo (an very usefull feature of HP-UX).

Re: cg6 from an ss2 to ss5, ok?


Thanks All,

It's pretty clean, and the fans work. But I'll have a closer look.
I just left it up over night and the cg3 was still
in one piece the next morning.
I'll be hoping it's a one off.

Paul.
