Android Macbook

I downloaded LiveAndroid, a LiveCD for Android running on x86 platforms from Google Code, to try on my Macintrash.

Currently I am running OS X 10.5.7 and Windows 7 (build 7100) on my Late 2006 Macbook (Core 2 Duo, T7200). I’m also using rEFIt as my boot manager. The Android LiveCD showed up as Tux on the boot screen and I got to the Android desktop with the message, “Please connect charger, the battery is getting low: less than 15% remaining”. I was running on AC and the battery was fully charged. I dismissed that warning and went into the console (alt+F1) to try to configure networking.

The liveandroidv0.2.iso supports DHCP, so I tried to get the network running using the howtouse live-android instructions:

ifconfig eth0 yourip netmask yourip’s mask

e.g. ifconfig eth0 netmask

That resulted in ifconfig SIOSIFADDR: No such device

I also tried ifconfig eth1 but received the same message. I didn’t look at the startup log. What’s the use of anything

Windows 7 – Can’t Play DVD Video

I’ve been trying several builds of Windows 7 x64 on my Macbook that uses the Intel 945 Express Chipset. Recently, I did a clean install of Windows 7 build 7100. The display driver that is installed is a Prerelease WDDM 1.0 Driver (

When I tried to play a DVD with Windows Media Player, I received the message “Cannot play DVD video.” Microsoft gives several possible reasons for this message:

  1. Your video card driver is out-of-date.
  2. Your computer is missing a compatible DVD decoder.
  3. Your computer hardware is not powerful enough to play DVDs.

Since build 7 is Windows 7 Ultimate, I assumed a decoder was built in to the OS. I was indignant that suggestion 3 was questioning the manhood of my Macintrash.

Then I remembered the OpenGL problem I had with one of my programs. After I installed the Intel Vista 64 bit drivers for the 945GM Chipset from, WMP was able to play DVDs. I’m not sure why the Prerelease WDDM 1.0 Driver didn’t allow the decoding, but the released Vista driver works – just be sure to run the installer in the compatibility mode for Windows Vista.

My Windows Experience Index also went up a tad compared to build 7068; compared to build 7000, the WEI from 2.0 to 3.0. So my computer is getting faster as it ages or Microsoft is improving Windows 7.

Windows 7 Build 7068 on a Macbook

I did an upgrade installation of Window 7 build 7068 (x64) over build 7000 that I installed in January on my Macbook (13-inch Late 2006 with an Intel Core2 Duo Mobile Processor T7200, 3GB RAM). Winver gives: 7068.0.amd64fre.winmain.090321-1322

I ran the Windows Experience Index assessment again, and the base score went up from 2.0 (build 7000 64-bit) to 2.8 (build 7068 64-bit).

With build 7000, my Macbook’s low score was because of the 2.0 subscore of the disk data transfer rate of the primary hard disk, a 120 GB Toshiba MK1234GSX. With build 7068, the subscore of disk data transfer rate of the same primary hard disk went up to 4.3.

With build 7000, the Processor and Memory (RAM) subscores were 5.0, while the Graphics and Gaming Graphics subscores were 3.1. With build 7068, the Processor and Memory (RAM) subscores were 4.8, while the Graphics and Gaming Graphics subscore was 3.1. The Desktop Performance for Windows Aero dropped from 3.1 (build 7000) to 2.8 (build 7068).

The main problem I’ve been experiencing with build 7000 is that Windows Explorer will get sluggish or hang after waking from sleep. Trying to switch directories or file copying, even locally, will trigger the problem. Ending the explorer.exe process and restarting the process doesn’t always solve the problem. A reboot does.

Windows 7 and OpenGL

I installed Windows 7 (64 bit) on my Macbook that uses the Mobile Intel 945GM Express Chipset. One of the apps that I use is ClearView, an RC flight simulator for radio controlled planes and helicopters, so I can learn how to fly my Heli-Max Axe CP. On the first run, ClearView said that OpenGL wasn’t installed. The Windows 7 Beta display driver (Pre-release WDDM 1.0) didn’t have OpenGL.

I installed the Intel Vista 64 bit drivers for the 945GM Chipset from, which installed OpenGL 1.4. ClearView seems to work OK.

July 22, 2009: Windows Update notified me that there was a updated Intel display driver for the 945 Express Chipset for Windows 7 RC. I installed it, version, and it runs OpenGL on my flight sim program. It also works with these Intel chipset families:
