How do I get dmidecode?

I use it in my BIOS Update add-on. Easiest way to get it, you can install that add-on, and it will be left in /usr/sbin/dmidecode.
The add-on does no harm, if there is a BIOS available for your system board it will be updated, otherwise it exits.

edit:
Or skip the add-on, and grab it directly:

# wget --no-check-certificate "https://dl.dropbox.com/s/wcbf6kiry1le87o/dmidecode?dl=1"

# /usr/sbin/dmidecode

Sounds great! Will definitely try this out.

Just a couple of questions first though:

1. I can't find any info on this add-on on the site. Can you direct me to it?
2. Would this version be compatible with the Pro Pioneer as well?

1. The add-on includes BIOS updates for some ReadyNAS models. BIOS updates can be needed for a variety of reasons for different models.
2. There is no BIOS update available for your model. The add-on should detect that if you tried to install it.

Edit: 2. Yes, the Pro Pioneer/BE, Ultra 6 Plus and Pro 6 use the same BIOS

Okay, thanks for the info.

I tried it on the Pro 6 and it gave me two prompts like such:
BIOS update encountered an error.
and then
The BIOS_Update_Package add-on has been successfully installed.

After that I could find dmidecode in /usr/sbin/dmidecode like you said. However, i was not able to get a speed reading off of the memory modules. Any idea why that might be? Is there any other way of determining the speed of them?

The reason I'm messing around with this is I had a 2x1GB kit of this memory lying around and after realizing the Pro 6 actually uses regular 240 pin SDRAM I decided to give them a go.
http://www.corsair.com/vs2gbkit667d2.html#tab5

They are rated at 667MHz and 5-5-5-15, but the speed says "unknown" and frontview says 4-5-5-15, so I'm curious what settings are actually used. Does the BIOS run them at 667 or 800 or does it go by the SPD always? If so, why 4-5-5-15? Is it actually overclocking them? :) They ran through the memory test fine though. I wanted to compare them with the one Apacer 800MHz stick that came with the NAS.

The chipset supports dual channel mode, so will two sticks put a lot of pressure on the memory controller you think? Will the heatsink be fine?

If this works fine I was thinking of going for a 2x2GB kit at 800MHz CL5 (which are still readily available) just to get some more headroom.

I know changing the RAM is not officially supported, but I'm just trying to figure what the BIOS is doing and what settings are being used, thanks!
