Re: Indy RAM

You can identify whether a SIMM is parity and FPM by reading the part number on the chips. See http://www.chipmunk.nl/DRAM/ Companies that service old Macs may have them in stock (but they mostly would not be parity). If you can't find it elsewhere you can use a company like MemoryX that carries all...

Re: Resizing AdvFS partitions on Tru64

AdvFS uses "domains", which are made up of multiple partitions. I don't have time to read the docs but it should be possible to create additional partitions and add them to the existing domain to increase the available space.

Re: VNC to Origin2000

X11 is a protocol between clients (applications) and servers (that manage the display). Display support is compiled into the Xserver. Under the X11 model, headless servers don't exist: the Xserver is always accessing the display hardware. To display remotely, you log into a remote host with the DISP...

Re: X11/Graphics Trouble Indigo2

Great.. So, is there a location I can manually check/modify the configuration? Good to see you got it working. For future reference, I think the way to do this is to do echo -n "1280x1024_60" > /usr/X11/Xvc/GR20_TimingTable but I've never needed it. I'll check sometime to see if this is c...

Re: X11/Graphics Trouble Indigo2

"unmanaged" from gfxinfo means that no Xserver owns the display. This would be expected when Xsgi is not running. When you use setmon , you need to give it the -x flag to tell it to make the setting the future default. That way it doesn't need to contact the Xserver (a point is that the DI...

Re: X11/Graphics Trouble Indigo2

I would pull the disk and put it in slot #1 first, because that's where the root disk is expected and it can sometimes make IRIX confused. Slot #1 is the bottom slot, which might be easier to slide into if the cover is off. Slot #2 is the top slot, for option disks or tapes, and slot #3 is the CD/DV...

Looks like the fluid loss problem is pretty serious (there are also a lot of material compatibility problems).

Re: Hot-rodding my G5 - storage performance

We inherited little endian due to x86's massive success, but I wonder why architectures went little or big endian in the beginning. Big endian seems to be logical, specially if you are reading memory dumps. They were conventions used in closed corporate cultures. IBM always used big-endian numberin...

Re: Indy overhead projector?

I'm not sure what we're supposed to be looking at. It's an OHP in a case?
The Presenter flat panel (for the Indigo2, Indy, or O2) has an open back in order to be used as an overhead display.

Re: Received an O2, now how do I get it to boot.

I would be inclined to believe IDE that there is a secondary cache (L2) error. It might be caused by a shorted connection, like a wire strand or stray solder ball under a cache chip. Testing with another CPU module would be the logical next step.

Re: your latest purchase

A country with two different voltages for household outlets would be quite odd. Fortunately Japan isn't so strange, it uses 100V throughout, but with two different frequencies (60 Hz in the west, 50 Hz in the east). A 16% difference in frequency is much less of a problem than 100% difference in volt...

Re: it would be cute if we had HDL for Irix

Sure. The open toolchains for Spartan6 were made possible with the Xilinx documentation (which was quite complete for their older parts) and analysis software such as DeBit.
