Users / Re: HELP! How do I add a media director for diskless boot?
« on: January 14, 2008, 01:53:48 am »
Hmmm, well that contradicts the Wiki ( and what I'm seeing. That’s not to say that the Wiki is not out of date or I’m doing something wrong. I'm trying to net boot a Dell GX50, it does not have a boot from network option in the bios but it does have a net boot option when powering on. On the main power up splash screen there are two options F2 for setup and F12 for network boot. When I attempt to use the network boot option it tries to connect but does not sees the core, so I assumed I needed to do what the Wiki said (i.e. set the MD MAC address on the core). I know the core NIC’s and DHCP server are working because LMCE can get to the web and if I boot the GX50 into windows I get an IP address from the core’s DHCP server. Any ideas why this isn’t working?

Users / HELP! How do I add a media director for diskless boot?
« on: January 13, 2008, 10:45:24 pm »
I have installed LMCE from the 7.04 from the DVD ISO and all went fine and the Core/hybrid is up and running. I have two NIC’s installed and working; ED0 and ED1 are both accessible. Ed0 is the LMCE DHCP internal interface and it is connected to a 10 port hub that has one other pc connected to it that I want to net boot from the core. So now I’m trying to follow the directions on the Wiki to setup the diskless boot system.

Heres the step from the Wiki that I’m stuck on:

“In LinuxMCE Admin go to Wizard > Devices > Media Directors. Add the media director if this is a new one, and set the Mac address. The Mac address should be a series of six 2 character sequences separated by colons, like this: 1A:00:F2:21:23:9F”

So I go to the admin site and go to wizard and find my way to the media directors and I see one MD listed “core/hybrid”. Seeing how the Wiki doesn’t explain how to add the new device I assume that I need to click on the “Add Device” button. After clicking Add Device I get a popup to select the device template. In the Device template pull down I select “Generic PC as MD” and click close.  The popup closes and I see the Media Directors admin page again but I don’t see my new device added? Even with a refresh there is still no new device added. What’s going on, am I doing this right? How is one suppose to manual add media directors? I even tried going in to the advanced devices menu and tried to add a new “top level device” and I can’t get that page to add a device either, no matter what template I select?

Users / Intel e2180 Core suggestions???
« on: January 11, 2008, 05:37:10 am »
Is anyone using an Intel e2180 CPU as a core? I'm wondering what mobo will work well with the chip and LMCE as a core not a hybrid. I really want o have SATA RAID 1 support and gigabit LAN onboard. I am currently a direct TV subscriber and would love to put 4 PCI capture cards in one core with an e2180. I am planning on using cards that do hardware encoding so the CU should not have to do much while recording. Pleas comment on your experience with the 32180 chip as a core I would also love to see system specs and power usage if you have them.

Developers / Re: Adding alpha blending to the Openchrome drivers?

I wish I knew, that's exactly the question I need an answer to  ;)

I'm new to LMCE and Openchrome; I have just started looking through their source today. It looks like there is support for overlays in Openchrome but I can't tell if the latest via chipsets are supported. It also looks like 3d DRI and vx are all supported but again not sure if the latest chipsets are stable.

If someone can help us understand what LMCE needs in the Openchrome drivers to at least support UI2 overlays I bet the two of us could make it work?

I'll keep digging around in the code and try to understand it better and let you know if I figure out what support is missing.

The HVAC control device on looks interesting but there is no basic UI for the every day user. Do you know if anyone makes a standard digital wall mounted thermostat that supports the insteon wireless or wired coms? I would love to simply replace my existing thermostat with an insteon supported device. If I could do that and control my lights I would be sold on insteon.

Does anyone know what it would take to add alpha blending to the Openchrome drivers to support UI2 overlays? I am an enterprise application software engineer and I have done some graphics programming but haven’t done any real driver work to speak of. I would be more then wiling to try to get UI2 overlays to work on the VIA systems if someone would be willing to point me in the right direction.

First, let me say thanks to Dan for the hard work with the insteon driver.

My biggest issue with insteon is that as far as I can see there are only light an appliance controls. Where are the motion sensors, entry control (i.e. door locks) and thermostats? If there was an up to date Z-wave controller supported I wouldn’t mind spending the money to get the devices that I want to control my house. So right now it looks like Z-wave has the most end device controllers but least support in LMCE and insteon has up to date support but lacking in end devices unless you are ok with the slower and less reliable X10 devices.

Looks to me like from a home automation stand point we are stuck between a rock and a hard place.

Is there a happy middle ground, what should someone do for an LMCE setup today? Does one invest in an old z-wave controller (if it can be found for a better price then on and more expensive/better (do you truly get what you pay for?), end device controls or wait for a new z-wave controller to be supported or start using insteon and wait to get more end device controls???? Better yet, could someone invest in both z-wave and insteon controllers and use X10, insteon and z-wave all controlled by the same LMCE core? That seems like the most flexible solution right now if you want full home automation but it may be a bit more expensive.

Users / Re: Energy consumption of core
« on: January 10, 2008, 05:22:03 am »
I have been looking for a good power saving solution for my core and I have been leaning towards the Intel e2180. It looks like a few other people have successfuly used them in there cores. I am also planning on using RAID 1 with only two 1TB drives to save a bit more power if I can’t spin the drives down when the core is idle.  Has anyone had issues or success with the e2180 and if so what mobo are you using and how many capture cards (i.e. video encode streams) do you have running at one time?

A first step any development team should take when it comes to power consumption is to minimize CPU and disk usage on polling tasks and use hardware to signal events asynchronously. For example, there is no reason why an update task has to run every few mins (or hours even) when we know that most updates are only available once every few days, weeks or months. Why should a task look every so often for updates or even scan the hard drive? Lets learn from systems like TiVo that simply look once a day at 3am when there should be little activity. Then, once the update process completes the disks should return to the state that they where in prior to the update. If all non user tasks where synchronized to run at a specified time when there is low user load and then return to a sleep state we would not have to worry about drives spinning up when there is no needed user or system load.

Also, I completely agree that LMCE should disconnect its media store from its system store to allow for media drives to spin down. However, it seams that there is a simple solution to this problem, use some form of NAS or another low power system to supply data storage and place that system in sleep mode when not in use (assuming that LMCE does not poll the NAS drives). Also has anyone looked into using 2.5 laptop drives in there core instead of the 3.5 inch high speed (10k rpm) power hogs? I know a lot of enterprise server solutions (specify HP servers) are doing that now, not only for power savings but also for space savings; you can fit a lot more 2.5 inch drives in a thin rack mounted server.

As an intermediate solution would it be possible to run the poling tasks and things like the myth scheduler on an external low power system (e.g. Via’s EPIA systems) and simply bring the core out of a standby or hibernate via wake on LAN (or hardwired power up signal) when specific events occur such as a scheduled recording is coming up or based on a household calendar or when a MD comes online?

Note: I have not yet used LMCE (but I will be soon) thus, I have made some assumptions based on what I have read on the Wiki and in the forums in the last few weeks. That is, I have no first hand experience so please feel free to correct me as needed  ;D
