low-power processor and motherboard

In an effort to find the lowest power system, I’ve started looking beyond the processor, where Intel’s Atom processor’s are a clear winner.

I read somewhere (didn’t keep a link) that the power usage of the older Intel 945 chipset on motherboards with older Atom processors actually consumed more power to run the motherboard chipset than the processor itself. Surely this is not right.

But it seems that Intel are on the case. The new NM10 chipset uses only 2.1 Watts of power and should be able to provide a chipset and processor running at 15.1 Watts. Very nice.

Now… next question is, which motherboard to go for. It seems that there are 3 candidates on the market at present:

  1. Foxcon D51S
  2. Intel BOXD510MO
  3. Asus AT5NM10-I

As far as I can tell these are all very very similar components. If there’s any significant differences between these, I’d love to know. Especially if those differences relate to running operating systems like OpenSolaris or Linux….

Mac IP printing without Bonjour

Bonjour is great because devices can be automatically discovered on the network.

However, I’ve got a faulty router that won’t allow bonjour to travel from wireless to wired ethernet connections.

So I was trying to figure out if there was a way to get the Brother Printer driver to work on the ip address, which I can manually set in the router, and not rely on Bonjour.

Here’s how I did it.

1. Give the printer a fixed IP address in the router’s DHCP settings. Alternatively you could also manually set the IP address on the printer.

2. Add the printer, like so:

 

Network printer by IP address

Network printer by IP address

Works a treat for printing.

DLink DSL-G604T Bonjour issues

It seems that the D-Link DSL-G604T wireless router has serious problems with Bonjour.

I have just purchased a network printer, which is automatically discovered over the network using bonjour. This technology is really great.

The printer connects by ethernet. One computer connects by ethernet – it works fine. The other computer connects by wireless, and it doesn’t.

To make things more strange, the wireless computer can ping the printer. But it won’t discover it over bonjour. If I connect the second computer via an ethernet cable and turn off the wireless connection, then everything works perfectly.

I read a similar story on the whirlpool forums where that router had a problem with music sharing between wired and wireless computers, and apparently the problem was fixed by a firmware upgrade for the router.

Not so lucky for me. I downloaded the latest firmware, and the same problem still exists.

If anyone has heard of how to solve this problem, please do tell.
