SGI-320, Win2k: some USB-, Power- and Video Problems

SGI-320, Win2k: some USB-, Power- and Video Problems

Post by David Pete » Tue, 03 Aug 2004 07:51:49


Hi all,

recently did a clean Win2k-install on SGI VW-320 dual 500MHz 512MB RAM,
80GB IBM GXP HD, PCI-modem, 1600SW display.

Works great but with below few glitches:

1.) ---------------------------------------

Some USB-devices connected via 4-port USB-hub only get recognized after they
are unplugged several times. From group reading I learned already that the
onboard USB on the VW-320 is problematic, and for devices other than SGI
mouse and keyboard that an extra PCI-USB-Card should be used.

Q: Will every modern PCI-USB-Card fit in the system, or is there a problem
with the supposingly special 3.3V design of the SGI-PCI slots?

2.) ---------------------------------------

The system seems to power down normally (although quite fast, takes only
couple of seconds to power down completely). But then it would not power up
unless the power cord is unpugged and re-plugged after a minute or so.

Q: Is the power problem related with the usb problem - or is that a separate
(known) problem with possibly some solution?

3.) ---------------------------------------

The VW-320 plays all videoclips like MPEG, ASF, WMV - but not clips from a
digicam with Motion JPEG compression. These only show up completely
distorted and with false colors. Codec is Morgan Multimedia MJPEG codec.
Latest DirectX 9c is installed.

Q: Is this a known problem with the VW-320?

Thanks for reading so far -

David.

Right.


It's not a special SGI design, 3.3V PCI are part of the PCI spec. However,
on PCs the 5V version of PCI is much more common.

You have to get a USB card that is 3.3V capable. All USB chipsets should do
3.3V but it might be possible that the cards PCB lacks the proper coding and
thus won't fit into the 320's PCI slot.


That's a separate problem and caused by the power supply. The PSUs in the
SGI320 often give problems, so instead of replacing it with the same type
I'd put a better one inside. ATX PSUs can be reworked to be used in the
SGI320...


Well, the cobalt drivers have some serious problems with DirectX and
Direct3D. These bugs never got resolved, and for sure never will be. So not
all software using these APIs run correctly on the SGI320.

But I think it's more a problem with your codec. Perhaps You should try a
different MJPEG codec...

Thanks. I'll probably get a 4+1 PCI USB card with nec chipset and TWO
PCB-gaps then:

Thanks again. I've read about that on Milton's btinternet SGI-site (BTW,
where has it gone, that great site? Seems that I can't go there anymore).


Right. OK. I'll try a different codec then.

Thanks for your fast and comprehensive help.

David.

Thanks for the information. Have you ever tried setting the registry key

SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\PowerdownAfterShutdown

to "0", and switch off manually after shutdown?

I can't try it out myself because I'm at a different system at the moment.

Looks good. Haven't seen a price but such card should go well below 10.-EUR.
If You want Firewire (the 320's Firewire ports have no real useful drivers)
then I'd suggest to get a firewire card as well (should be around 4-7EUR)...


It's gone? Well, You can try to mail Milton and ask what happened...

Thank you. The USB PCI card has been ordered today. Firewire probably will
not be required cause major video editing and the like will be done on a
different machine. This one is used (by our children's Grandma ) for
general text processing, internet access and photo edititing. EUR 450,-- for
a beautiful system that once was DEM 20.000,-- was just such a irresistible
bargain. I'd even like to have a pair of the amazing 1600SW Monitors on MY
desktop...


Had done that already, but so far with no success.

Thanks, David.P
