I haven't used any of the units that support ADB (just old-fashioned PC
keyboard and mouse ports), so I don't have specific model recommendations,
but I can tell you this:
Not many of them do well with monitors at extremely high resolutions/refresh
rates. The picture can get wobbly or washed-out. If you're planning on
working at 1600x1200 or so, make sure you have a money-back guarantee so you
can test it with your equipment. Also make sure you get really high-quality
video cables.

Well, I wish that were the case. The manual clearly states that jumper J1F2
is the BIOS Configuration Jumper. When set on pins 2-3 this displays the
Configuration Manager program (BIOS editor). This has worked on occasion,
but this error baffles me.

Did you disable the splash screen?
You don't need to touch the jumper on the mainboard if you have the splash
screen enabled. I have had my board for about a year and I have never
touched that jumper.

Is English your native language? Normally I don't bring it up, but
your articles are _really_ difficult to understand - some of your

If it is your native language, we can save a whole lot of time if you

See, the reason a lot of people are seeming confrontational is that
we're having to extract information from you as if we were pulling
teeth. What have you tried? Do you get any error messages? What
_exactly_ is the error? You said at first that Linux didn't detect
the card, but this is obviously false, as /proc/pci lists it.

I assume, then, that this isn't a PnP card. You need to tell Linux
the relevant numbers before it will work.

Then I'd guess it's not a PnP card. Read the card's manual to
determine how to configure the I/O address, and IRQ and DMA numbers.
Then load the appropriate module and explicitly specify those three
numbers (you may not need a DMA, it probably depends).

What does being in runlevel 3 have to do with installing an expansion
card, or even with installing _drivers_ for an expansion card?

Assuming you have the appropriate drivers set up, press
Ctrl+Alt+NumPadPlus to cycle through the resolutions. Or you can edit
your /etc/X11/XF86Config (or /etc/X11/XF86Config-4) file, find the
right entry, and change the order of resolutions.
You might see something like:
Modes "1024x768" "800x600" "640x480" "512x384"
Put the resolution you want as default first. Be sure to do this for
the correct pixel depth, as there's a different section for each.

Have you ever updated the BIOS then? Because according to the manual, you
have to move that jumper to reset the BIOS. Just wondered. As for the
splash screen, the guy who thought he could help turned that screen off as
it was supposed to speed up the boot process.

Yes, I have updated the BIOS a bunch of times. The board I have originally
came with ver 215, now I'm up to 248. I have probably updated the BIOS at
least 5 times, probably more. Where do you see info about upgrading the BIOS
in the manual? In my manual it doesn't say anything at all. I downloaded the
pdf file for the BIOS and it says to follow the instructions that come with
the BIOS upgrade but the upgrade does not make any mention of moving any
jumpers. The BIOS also contains a button to reset the configuration and that
should actually be good enough.
I don't think the splash screen slows down the boot all that much. On my
machine I have an Adaptec 29160 SCSI controller, this controller is
definately the slow poke of the boot process. The OR840 boots pretty fast
compared to my old DK440LX, now that thing was really slow.

One other question, how long does your system take to boot up? Just
wondering why you turned of the splash screen. Even with my SCSI adapter I
am usually through the POST in about 15 seconds.

I haven't dared to o/c yet - without that, I haven't seen *any* APIC

Subject: G450 TV-Out under Linux
From: David Maslen <[EMAIL PROTECTED]>

Some feedback for you.
I purchased a G450 recently. I was interested in the TV-Out feature,
and was hoping to use both my PAL Television set and 17" monitor with
Xfree86. I now discover this feature is unsupported.
My decision to purchase a Matrox card was largely based on the
excellent reputation I believed Matrox to have in relation to it's
history of publishing video card specifications to Xfree86 developers.
While I am impressed with the G450, and the linux forums you provide,
I am a little disapointed with my Matrox purchase and would hesitate
to recommend Matrox video cards to fellow linux users in Australia.
While I prefer the open source model, I would probably be satisfied
with binary drivers which would support the the matrox card on an open
source operating system like linux.
I do consider it my own fault that I purchased a G450 rather than a
G400, however my purchase decision was largely based on brand loyalty
and my assumption was "a higher number will be better". I should have
done my reseach prior to purchase. I hope to do better next time.

I have an A7V133 and love it.
Yes, benchmarks can distinguish between DDR and PC133 memory, just like
they can distinguish between 800 and 1300 MHz processors. But _YOU_ almost
certainly won't be able to, EXCEPT IN YOUR WALLET!
For all but the tiny percentage of programs which can execute mostly
cache-bound[##], the core speed of the CPU is almost irrelevant: what
matters is memory speed. For memory speed, what matters is ACCESS TIME and
not data rate. Those DDR RAMs have the same 60-70 ns (or so) access time as
PC133 RAMs.
[##] "mostly" is >98%; for even a 3% cache miss rate the CPU
wastes time waiting on memory (in our simulations, at least).
This is a highly technical question of how the data actually gets from
memory to the CPU (reads outnumber writes by typically 4:1 or more, so
one normally optimizes for reads). I do NOT know what these motherboard
chipsets can do, but I do know about our memory controllers (this is
for a PowerPC system, not Intel/AMD). Our current memory controller takes
12 clocks per memory access of which the last 4 carry data. So DDR memory
would reduce that to 10 clocks, less than 20% improvement. BUT -- that
improvement is LOST unless the memory controller can overlap a sufficient
number of requests to keep the memory bus occupied. Ours can have 4
requests outstanding, but for DDR that is not enough, and there is no
advantage whatsoever of DDR over PC133, IN OUR DESIGN. YMMV, and I
suspect the motherboard chipset designers worry about this a lot....
Unless the motherboard chipset can keep at least 8 memory requests
outstanding AND OVERLAP THEM, and unless you have multiple DIMMs which
are appropriately interleaved (so different requests hit different
memory banks), DDR will have essentially no advantage over PC133 at all.
(This assumes the processor is pipelined enough so 8 memory requests can
exist.... Our PowerPCs can just about do that, but I don't know about
Pentiums or Athlons....).
I am not the hardware designer of the system I mentioned, I
do OS software for it. It is an embedded PowerPC "supercomputer
on a board" completely unrelated to the PC market. I know enough
about this to be dangerous.... And I know NOTHING about the
details of Pentiums or Athlons or PC chipsets.
