Over the next year I predict that I will need another 2-6TB of storage to cope with added data volumes (I intend on starting to film in 1080p resolution which is about 4GB for 15min of video). Currently the largest available drives are 2TB at a cost of about $300. The issue is not with the drive itself though. It is about how and where do I connect the drive to the network.

External USB/FW drives are too slow for real use (they are OK for incremental local backups though). So the remaining solution is some kind of NAS. My HTPC/Mac (see below) will fulfill that function. It is attached via 1Gbps Ethernet and has six drive bays available and a large power supply. The unit already sports a 250GB boot drive and a 1.5TB data drive.  The issue is that with that all the SATA ports on the Atom board are used. So the next drive will have to be attached to an extra SATA PCI card (which will have to be Mac compatible).

The new Snow Leopard also supports wake-on-use. That means the machine will wake on access of a drive. Currently I still need to wake it manually via WoL. Remains to be seen when Snow Leopard (10.6) will be “available” on the Intel Atom boards with all needed features supported.

The issues I have with data in my private home start to mirror what has been happening for quite a while in the datacentres. Not only does that mean I need ever more technical know-how at home to cope but it also means that something like the solution below gets interesting.

This is of-course too large for private use but it does solve some of the issues you might encounter when building your own NAS.

One other thing that is hugely annoying in NZ is the lack of broadband flatrates. This effectively prevents you from performing sorely needed and large off-site backups. Currently I solve this problem by storing a USB hard drive off site. This HDD contains a copy of the most important data that I have (by no means all the data!).

So, what have you done for your backup today?

[Update] With the upgrade to 10.5.8 the sleep mode breaks. There is currently only a fix for Voodoo kernels but not the plain Vanilla ones. Very annoying this is. Maybe I’ll have to re-install.

[Update 2] I have re-installed to 10.5.6 because that gives me sleep and Atom 330 Hyperthreading. I’ll then wait & see what Snowleopard brings…

As I said in post 1 I got my first inspiration from here:

http://www.osnews.com/story/21564/Building_a_Hackintosh_Apple_Can_t_Sue_You_

Basically the interesting part being able to use the standard OS install. I pretty much followed the instructions on that page. But here I’ll also give some additional hints that might make your life a little easier.

So with a USB stick, a freshly burnt boot-132 CD and the Mac OS X Leopard DVD (10.5.0) I ventured to my new Atom powered sleek SilverStone Mac (or do I call it a PC?). Before I started though I had deleted all partitions off the hard drive so that the Mac OS X installer would not have any issues trying to delete Linux or Windows partitions. This I did with a Live boot CD running Ubuntu 9.04. The Partition Editor under the System menu did the trick.

That done I inserted the boot-132 disk and started the HTPC. As promised it came up with a prompt and after exchanging the DVD the new OS was happily installing. Note to partition the drive correctly before installing though.

The install took about an hour. Create your user & stuff and you’re ready to reboot. You will still need the boot-132 CD to start into your partition until you have installed the bootloader Chameleon.So reboot now and see what happens.

*TaDa*

You have your first OS X start! Probably you’ll only see a 1024×768 resolution but that’s 100% OK.First install the 10.5.7 combo installer from Apple. You might run into a system crash when you reboot. This is due to problems with hyperthreading (HT) on the Atom CPUs. This is probably due to the processor not being interpreted correctly but I did not yet figure a way of fixing that. Maybe someone out there has a clue. To get it running you therefore have to turn off hyperthreading in the BIOS.

Now start executing all those steps in the link above. You’ll need to install Chameleon, Kexts and the other goodies. One thing the documentation sort of misses is the fact that you manually have to set the Mac OS partition to be active if none of the tools has done that for you. Details for this can be read-up here.

Should you have more than one partition the boot manager will also come up every time to ask you where to boot from. If you don’t want that read up here how you can change on the boot loader. For me it were the entries…

<key>Kernel Flags</key>
<string>rd=disk0s2</string>
<key>Timeout</key>
<string>4</string>

…in the com.apple.Boot.plist file.

One thing to note with the Intel D945GCLF2 board is, that the Realtek NIC is not fully 100% supported and the above description does not mention that. Get the Kext from here and install it with the OSx86 tool. All networking now works like a charm.

Finally repair disk permissions and install

If you have done all of the above you should be able to recreate this screen:

The important detail being…

If you do have the good fortune of having a SilverStone case with a display you will now need to get the display to work. the easiest way I found is by using the linked installer for LCDproc from here:

http://www.insanelymac.com/forum/lofiversion/index.php/t83598.html

I also recommend Plex for the movie experience (or just stick to FrontRow for now). Perian is also a valuable asset to have for those video codecs. XSlimmer (see below) can also help with cutting down the space used by applications a bit.

The set-up has now been running a couple of days and I’m very happy. Two things remain to be done:

1. I need to get 5.1 audio to work. So far no luck (or figure out a way for the on-board digital out to work)
2. Find a way to activate the buttons and volume controller from the SilverStone case.

Although the latter is not that important to me. I’m content and am totally amazed at how well this has worked. The Atom is also a lot faster than I would have expected. It probably isn’t as fast as a Mac Mini but then I wouldn’t have expected that but it is a heck of a lot faster than my 1.42Ghz Mac Mini I had before (even with a 250GB 5400RPM drive upgrade!).

So the experiment was a success and I can now attack the final little nigglies.

Since I have a Mac OS X Leopard family license with two licenses left unused I thought this might really be a good idea. If it is legal I’m not sure (am no lawyer). I do know though that Apple earns on average $2000-$3500 from us every year in software and hardware. I think that warrants me going a little astray for the fun of it.

In the end I just love the tinkering. I think it’s the same genes that are responsible for grown men to play with toy trains.

So what did I do…. firstly I had to get all the components.

1. Intel Atom 330 Motherboard D945GCLF2 (from Paradigm PCs in Wellington – not the cheapest but reliable & quick)
2. 1GB Ram DDR2-5300 (had that already)
3. WD 250GB 7200RPM HDD (had that already)
4. Pioneer DVD-RW DVR-110D (had that already)
5. SilverStone LC16M HTPC case with a Task 450W low noise PSU

The SilverStone case was a stroke of luck. I got it cheap off TradeMe and it was exactly the thing I was looking for. Eventually the hard drive will be exchanged for a 1-2TB drive(s) but I am waiting for the big drives to come down in price a little and for this experiment to work before spending more money. So far I have now spent just over NZ$400 for the set-up.

The  Intel D945GCLF2 mainboard with its dual core 1.6Ghz Atom 330 processor is a sweet little thing. It definitely has its drawbacks. It only has Intel GMA950 integrated graphics, 2GB ram max, only 2 SATA ports, only one PCI expansion slot, no Firewire and the chipset could be more efficient. But it is very compatible with Mac OS X, has a plethora of USB ports (4 x front & 4 x back), is available and is dirt cheap. My research on the Internet said that it definitely wouldn’t do 1080p. Since our TV is 720p/1080i only I wasn’t too worried.

I would have liked to get one of the new Atom + Nvidia ION chipset mainboards but there’s none to have in NZ for a while and their compatibility with Mac OS X isn’t proven yet. I also anticipate them costing NZ$350 and more.

So by last Friday I had all the parts sitting right in-front of me.

(LtR: DVD, HDD, Mainboard, RAM and USB stick)

and the case…

And I must say the case is absolutely divine. It is just the right size. Has space for (at least) 6 hard drives and can be fitted with fans left-right and center. It is solidly built and the front is really nice aluminum. So I set about setting it all up. It would be a challenge to get all the switches, display and other gadgets to work under OS X.

More tomorrow….
