Default 12V computing?

Does anyone on the list have recommendations on 12VDC based hardware which
runs a stock Centos 4 (or even 5)?

Any ideas if this can run centos with out a special modifications?

Jason,

I don't see why the 32 bit version of centos would not run on that
hardware. Despite the fancy processor name, it still has to work
with the i586 command set (at the worst).

There's no such thing as a "12 volt" computer... unless you're looking
at some sort of weird industrial setup. That motherboard runs of a
standard ATX power supply just like any other beige/black box would.
You can buy special electronic power supplies which convert 12V dc to
the ATX standard, these are often used for putting a computer in a
car. Search the mini-box site for "pico psu"

Yes. We are trying to minimize costs ( certification of deviation from
baseline centos/RHEL vs. hardware costs) in a 12VDC only environment.

The documents I have read disagree. See the picture too:

http://resources.mini-box.com/online/MBD-E-C7VCM/moreimages/image2.jpg


notice the modified ATX connector to only have +12 and ground.

We are aware of these, but that would be just another part at another cost,
and another testing point, ...

by 12VDC, do you mean regulated 12VDC +/- xx%, or vehicular 12V which
typically is 11-14V, and should be engineered to not burn up on 9-18V
with noisy spikes et al?

I have run CentOS 4.5 on this platform without problems.



I wouldn't expect any issues with CentOS 5+.

We will have a regulator.

are these Via C7 processors i686 compliant? I think the earlier
Cyrix/VIA stuff was i586 only. I thought CentOS5 was i686 only,
and no longer supported i586 level CPUs ?

Default 12V computing?

If you want to minimize power costs, look to higher voltage, not
lower. Run your computers off 208-240 volts instead of 100-120. If
your supply is not auto ranging, make sure it's set to the high / 230
setting.

Having a massive 12v power supply to run several computers isn't going
to save any power. Your second picture just demonstrates they have
integrated the electronic power supply into the board, thus when your
power supply fails, you can replace the entire system instead of just
a component. It is doubtable than a 12VDC to ATX converter is any more
efficient than an AC-line to ATX converter. Plus the cabling to
transfer 12V at 10a+ more than a few feet is going to be massively
expensive - look up the I2R losses on google.

In regards to cpu support, the via website mentions the C7 compares
directly with the Pentium IV, which would make it a 686 class cpu.
Additionally, they claim support for these extended instruction sets:
MMX, SSE, SSE2 & SSE3

One thing you might want to consider, is DIY blade computing. With
some clever wiring, you can splice the ATX connector harnesses from
several dead power supplies onto a modern high wattage psu, providing
power for 4 to 6 low-end system boards arranged in a stack. A new "80
PLUS" rated 500-600w psu should have no problems. Pick one from the
stack to be the 'master', and toss a hard drive on it, the rest can
net boot from it.

Default 12V computing?

there are computer systems that take 12VDC
(for example the PC-104 type and others). such
a computer system is a box that has a connection
for 12VDC. inside the box is a power supply that
takes the 12VDC and presents the +12VDC, -12VCD,
5VDC, and -5VDC that's needed by the various
electronic subsystems that make up the computer.
the installation of linux (or any other OS)
is independent of the power requirements of the
computer system.
