Windows Server 2012 on a Macbook

Posted by Mr. Leslie Wong On March - 23 - 2013

Server Manager, Windows Server 2012

After the failure of an old computer running Windows Server 2003, I setup Windows Server 2012 on a Macbook.

Years ago, I set up a Sony Vaio PCG-Z505HS running Windows Server 2003 at home so I could keep up with Macs and Active Directory. When I recently experienced problems with DHCP and DNS, I discovered that the Vaio had died. There was no LED power indication. My troubleshooting consisted of jiggling the power connector and checking the power supply voltage. When I measured voltage from the AC adaptor, I gave up, using the rationale that it had lived its useful life. The Vaio, with a Pentium 3, 500 MHz CPU, was introduced in January 2000.

Coincidentally, I had a hardware failure in my Macbook (late 2006), so I decided to repurpose it as a domain server using an evaluation version of Windows Server 2012.

The Windows Server 2012 installation was simple using the Server with a GUI mode installation. The Server Manager and configuration tools greatly simplify the setup. With Windows Server 2012 on a Macbook running silicon introduced in 2006 – an Intel® Core™2 Duo Processor T7200 that has Intel® Virtualization Technology (VT-x), the next step is to try virtualization. As a Macbook running OS X, I successfully ran VMware Fusion VMs running Ubuntu and Windows 2000, though I forsee the 3 GB of RAM in the current system will be a limiting factor.

The best part about running an Active Directory domain at home is joining computeres to the domain. The welcome message says, “Welcome to the lower_slobbovia domain.

Macbook in a Mini-ITX Case

Macbook (late 2006), disassembled

 

My Macbook (Late 2006) has gone through many modifications and operating systems. Recently, it decided to stop responding to keyboard or trackpad input. Instead of trying to replace the trackpad/keyboard cable (which I’ve done once already), I decided to put logic board of the Macbook in a Mini-ITX case and try an evaluation version of Windows Server 2012.

ifixit’s MacBook Core 2 Duo Logic Board Replacement guide was helpful with the disassembly. After removing the logic board, I stripped the bottom case of the remaining parts (SSD, hard disk, speakers, display, etc). The MacBook logic board was short enough to fit in the case with the ports and connectors lining up with the opening for the Mini-ITX backplane.

I thought using the Macbook bottom case would be the best way to mount the system board because the case helps to align the MagSafe connector and the fan/heatsink assembly. I also wouldn’t have to mount other stand-offs in the Mini-ITX case. I used Dremel cut-off wheels to cut down the case bottom. To mount the logic board in the Mini-ITX case, I used double-sided foam tape.

The wiring for the ancillary devices – Wi-Fi, Bluetooth and speakers – were routed around the inside of the new case. The Mini-ITX case came with a bracket to mount 3.5″ hard drives internally but with non-standard headers on the logic board, I abandoned that idea. There was also a power supply, which I removed. I wired the power switch on the front of the case to the trackpad/keyboard connector on the logic board.

I had already removed the DVD drive when it stopped working in the summer of 2011 and replaced it with an SSD. I used double-sided tape to mount the SSD and the second hard drive to a bracket mounted above the logic board. Eventually, the short cable for the second hard disk failed and when I replaced it, the connector on the logic board failed from too many insertions.

When I first powered it on, it actually worked. The Mini-ITX case is slightly larger than a Mac mini (200 x 225 x 56mm vs 197 x 197 x 36mm) and slightly less attractive but it works. My only regret was breaking the circuit board for the system LED when I was disassembling the case.

Raspberry Pi Webcam

 Raspberry Pi Webcam

 

I’ve had a webcam serving live images using WebCam2000 running on my Macbook. I recently bought a new webcam, a Creative Live! Cam Chat HD (it was cheaper, $25, when I bought it August 2012). The previous webcam I was using, a Vivicam 3350B (I bought it on Woot! for $8.50 in 2005), didn’t have a Windows 7 driver and I was using Windows XP Mode and Windows Virtual PC - it was a little cumbersome.

When the Raspberry Pi was released, I thought it would be a great webcam server. I ordered one from Allied Electronics last July, but they never had stock. When Adafruit started selling them, I bought one.

After I acquired a compatible USB keyboard and dug up an Intellimouse Explorer 3.0, I started out with the 2012-09-18-wheezy-raspbian image. Googling found a Romanian site, BobTech, with an excellent tutorial for setting up a Raspberry Pi streaming webcam (English Google translation). Basically, the instructions just worked.

Later, I bought an Edimax EW-7811Un USB Adapter and with the current 2012-10-28-wheezy-raspbian image, WiFi was even easier to setup. The only change I made in the network setup was to give the Raspberry Pi a static IP address so I could find it. I edited wlan0 section in /etc/network/interfaces:

iface wlan0 inet static

address 192.168.1.115

netmask 255.255.255.0

gateway 192.168.1.1

nameserver 208.67.222.222

wpa-ssid “Skynet”

wpa-psk xxxxxxxxxxxxxx

I made a change to have MJPG-streamer serve a single image instead of a stream. Instead of using http://raspberrypi:8080/?action=stream, I used http://raspberrypi:8080/?action=snapshot. I use a script to reload the page every 10 seconds.  In mjpg-streamer.sh, I set FRAME_RATE=”15″ You really don’t see much action unless it’s windy.

Once the Raspberry Pi was setup, I used puTTY to connect to it, so I can start mjpg-streamer and do other things without having the Raspberry Pi connected to a monitor.

Windows 8: “Tough Luck, Bub”

Posted by Mr. Leslie Wong On October - 26 - 2012

Today I purchased and downloaded Windows 8 Pro on my c. 2003 Shuttle SB51G computer. It has a Pentium 4 2.8 GHz CPU. At the end of February 2012, I was able to install the Windows 8 Consumer Preview on it. Last June, I tried installing the Windows 8 Release Preview, which didn’t work.

I started the upgrade purchase through the Microsoft site and one of the upgrade adviser warnings said that the NX bit needed to be enabled in the BIOS. I knew that my CPU (Northwood) didn’t have this feature which was also the reason the Windows 8 Consumer Preview wouldn’t install. I still completed the purchase knowing that I would use the license on another computer. The Windows 8 installation procedure went through like everything it was fine. It was, until the reboot:

Windows 8 Your PC needs to restart

 

The message on the reboot said, “Your PC needs to restart. Please hold down the power button.” This same message was displayed after several cold boot attempts. The error code, 0x0000005D, with the parameters 0x030F0207, 0x756E6547, 0x49656E69, 0x6C65746E, as far as I can find, refer to an incompatible CPU.

I think it would have been nicer on Microsoft’s part to say, before I plopped down $39.95, that Windows 8 wouldn’t work with my CPU. I can imagine this happening to a customer reading the hype about Windows 8 and trying the upgrade, paying for it and then getting a cryptic message. It seems to be Microsoft’s way of saying, “Tough luck, bub.”

I restored XP from an image, and my ancient computer is back to being a file server.

Windows 8 on a Macbook

Microsoft Windows 8 Release Preview on Apple Macbook (Late 2006)

 

I installed the Microsoft Windows 8 Release Preview (x64) on my Apple Macbook (Late 2006). Over the years I’ve upgraded my Macbook’s hardware – it now has 3 GB RAM, a 120 GB OCZ Agility 3 SSD and a 320 GB Western Digital WD3200BEKT hard disk. I use rEFIt as the boot manager for the two main operating systems that I use, Windows 7 and OS X Lion.

I ran the Windows 8 setup program from an external DVD drive while booted to Windows 7 and the installation took about 25 minutes. Everything worked pretty well except the audio. I could see by the red glow coming from the audio jack that it had to defaulted to the SPDIF (digital) output. I installed the Bootcamp 4.0 IDT Sigmatel audio drivers and the analog sound output started working.

Thanks to Paul Thurrott for the instructions on setting up Windows Media Center, I was able to get the TV tuner working after I installed the Silicon Dust HDHomeRun TV tuner Windows drivers.

Once I got the dual monitor setup working and installed Google Chrome, I realized that Windows 8 is pretty much like Windows 7, except for the Metro interface. It seems that Microsoft’s goal with Windows 8 is to simplify Windows with Metro. The side effect of this is hiding everything that is of use to the power user – which made the learning curve going from Windows 7 to 8 slightly steeper. Fortunately, switching between Metro and the desktop interface is simple. The main problem with the Metro interface for me (besides that you can only see one running app at a time) is that I would never use the apps that are tiled on the main screen.

When I realized it would take me a week to install everything else to get to the equivalent of the working system I had on Windows 7, I did an image restore back to Windows 7.

I’m not so down on Windows 8 now that I’ve used it for a while. Microsoft has made improvements in Windows 8 that are helpful to the power user – Windows Explorer – now called File Explorer – is much more robust, for example. Windows 8 even runs fairly quickly on my 5.5 year old hardware and it only took about 30 seconds to boot. So while it looks like Windows 8 will run well on this legacy system, unfortunately Apple won’t be supporting my MacBook (Late 2006) with it’s next OS, Mountain Lion.
