It’s great to finally solve a Blue Screen of Death (BSOD)

Wed, 29 Oct 2008 05:53:57 -0500

I've been using VMWare Workstation for over 8 years, and I love how it allows me to setup different operating systems on my workstation for evaluation, test, special connectivity, or software installation and operational testing without any risk to my base OS installation. I am currently running Vista Ultimate x64 with VMWare Workstation 6.5.

Recently, after upgrading to the latest build of VMWare Workstation, I started experiencing computer freezes when I would turn on the monitor in the morning. I would have to reset my workstation, and 9 times out of 10, one of my RAID 0 arrays would need rebuilding, which required me to boot into Safe Mode, allow the rebuild to complete, and then reboot normally. This time lost was starting to mount, and I was getting extremely tired of it. Late last week, upon re-booting, I got a so-called Blue Screen of Death (BSOD) indicating an INTERNAL_POWER_ERROR (0xA0). And I couldn’t even boot into Safe Mode, despite repeated tries with some intervening reversions to BIOS defaults. I wasn’t able to find a lot of good information (via a web search) on this BSOD, until I happened on an article on Scott Hanselman’s Blog. Hmm, he says VMWare might be to blame. And it turns out it’s a power transition issue with the USB connection that Bluetooth wireless keyboards and/or mice use via their dongle. I have a Microsoft Bluetooth Wireless Elite Keyboard & Mouse, and with unplugging the Bluetooth dongle or uninstalling VMWare being the only workarounds, I was in a bind. Heck, I couldn’t even find the supposed offending driver, VMKbd.sys on my system! After a lot of searching and testing, I think I found a solution buried deep down in one of the VMWare Community forums postings. Here’s the essential part of that forum post located in the middle of this page:

1. Open Regedit.

2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E96B-E325-11CE-BFC1-08002BE10318}.

Here you will find an "UpperFilters" param of type REG_MULTI_SZ with a value like: "kbdclass vmkbd". If you open it up to modify it, you will see one driver name per line; notice that vmkbd by default is the last in the list. Edit (Cut and Paste) that parameter by putting the vmkbd entry to be the first in the list.

Note that in some cases "vmkbd" can be named differently: vmkbd2, vmkbd3 - it does not matter. It is probably because you have installed a newer version of VMWare over the old one or something like that, and the previous driver was not able to be delete it from the registry. Remember to re-check this registry entry the next time you upgrade VMWare.

3. Reboot and you should no longer have any BSOD’s related to this issue.

I’ve had no problems re-booting after a critical out-of-band security patch and some Windows Updates, no freezes have greeted me upon arising, and I’ve had the chance to actually get some work done this week. Hope this helps.

iPod Envy? Cook your Windows Mobile 6.1!

Wed, 24 Sep 2008 22:08:26 -0500

I've been using Windows Mobile phones for a few years on the Cingular and AT&T networks. I currently own an AT&T Tilt, which is actually an HTC 8925 (or TyTN II, or Kaiser) for those of you who care about such things. It was loaded with a second release of Windows Mobile 6 when I got it last March. My previous phone was a Cingular 8525 (which became AT&T overnight it seemed), and it came loaded with Windows Mobile 5. Since I'm the curious sort, I soon discovered that the XDA Developer Community was THE place to find out everything about PDA's and SmartPhones -- from where to get the best carrying case or audio adapter, to more esoteric subjects, like how these devices actually work at the hardware level. There are sections for every single PDA/SmartPhone you've ever heard of, with active participation by developers and power users of each.

After a lot of reading on XDA's Forum and Wiki sites, I learned that these devices run on a firmware image, called a ROM (or Read-Only Memory), that is developed by the manufacturer (in this case, in partnership with Microsoft) and loaded by the carrier, and that the carrier's own special programs are loaded from another area, called the Extended ROM. I also learned about the special firmware that allows these devices to actually communicate, called the Radio, about the bootloader, and a ton of other tips about customizing your phone to the way you work. I guess I became a tweak addict. Hello, my name is Bob, and...

It wasn't long before I discovered that many people were unsatisfied with the pre-loaded operating system and features delivered on their phone, and were customizing their phones with not only new features developed by, and offered for free to, the XDA community, but were also making entirely new ROM images, and flashing them -- tech speak for updating your phone with new firmware.There are some very bright people in this world, and I suspect a large percentage of them are in the electronic engineering field. I was simply amazed at the abilities of some of these folks, with handles like CusTel, kypher, and pof, who were simply brilliant in their ability to reverse engineer devices, extract or decompose ROM images, and understand and explain firmware code. They did this to make tools that could be used to 'cook' new ROMs -- tech speak for building a new ROM image from component parts -- as well as allow new Radio's to be loaded as the manufacturer's developed them. The frequency with which new ROMs and Radios appeared on the site made me start to suspect that the sources these folks were using were being seeded to the community by the manufacturers and carriers as a sort of Alpha test cycle, or that some participants in the community actually silently worked for the manufacturers or carriers. That said, please note that there is no pirated software, or warez, available at XDA-Developers. In fact, posting any can get you permanently banned from the site.

As I sat there with my Windows Mobile 5 8525 long after Microsoft had released Windows Mobile 6, and waiting for AT&T to get around to releasing an update, I started to think, "Why wait for AT&T? I think I can flash my phone with one of the WM6 ROMs being cooked at XDA specifically for the 8525." And, even though I eventually waited for AT&T to release their own update, I ended up flashing my phone with a different ROM -- one that was a later build of Windows Mobile 6, did not have any of the additional software that AT&T preloads (and that I simply did not find useful), and as it turned out, one that fit the way I use my phone to a 'T'.

After nearly two years of rough and tumble service, that phone woke up one morning last March with a white screen. I could get to it remotely while docked with a great product I bought, called SOTI Pocket Controller, but its display was finished. Using Pocket Controller, I was able to run some backup software, and otherwise get my phone ready for a warranty return to HTC. I was told that would take 3-6 weeks, and if you're like me, your cell phone is like a lifeline. So, off I went to the AT&T store, thinking I was going to get a throwaway flip phone to tide me over. But at the store, I met the Tilt, and, it was love at first site. This phone has a 400MHz processor, 256MB of ROM, 128MB of RAM, 65K of colors on a QVGA screen, takes micro xHD storage cards, has a 3 megapixel camera, wireless-G, Bluetooth, and a GPS, and when you slide the screen away to reveal the QWERTY keyboard, the screen tilts up at a readable angle (the 8525 screen just slid out). It also came with Windows Mobile 6 loaded, and with the promise that Windows Mobile 6.1 would be available "any day now". Where have I heard that before? But I was given upgrade/renewal pricing, and that was that.

So I got my new Tilt home, and immediately did a hard reset to clear it to factory state. This time, I did a soft reset just after completing the initial screen alignment. This bypassed the AT&T custom software load, and gave me a basic WM6 phone with the essentials (Office Mobile 6 being one of them). Of course, I learned that I could do this at XDA.

I immediately switched my preferences at XDA from the 8525 to the 8925, and as I read the wiki and forum topics for it, I discovered that some challenges lay ahead. The display driver had problems (with a Class Action law suit to boot), there was no Flash for the camera, and flashing this phone with a new ROM or Radio was a little more complicated than it was for the 8525. So I continued to read the XDA Kaiser wiki and forums (highly recommended), and gather my courage.

A few weeks ago, my Tilt's battery died evidently in the middle of an important registry write, because it started to act very strangely and would not boot correctly. Suspecting a corrupted registry, and coincidently, the day the new AT&T WM6.1 upgrade was released, I downloaded a few tools and the AT&T ROM, went through a few very important preliminary steps, and flashed my Tilt. I did the soft reset thing, and played with this ROM for a day or so. Not being overly impressed, I ventured into custom ROMs for the Kaiser, and after trying several different ROMs and Radios, I finally found a combination of ROM, Radio, applications, and skinning that is just a joy to use. Again, due to the sheer genius of the members of the XDA community, the HTC Diamond User Interface, called TouchFlo 3D, was extracted and configured to run on the Kaiser as a 2D variation, called Manilla 2D. It is cooked into the ROM I am currently using, called HyperDragon III Pro. Here are a couple of screenshots of my current setup, grabbed using Pocket Controller.

You simply drag your finger over the items along the bottom bar, the Icon appears with the background dimmed, and when you release your finger or stylus, you're on that screen. There is a nice Home tab with the clock, alarms, call history, and next calendar appointment. There are also tabs for Contacts (with pictures of your fave's right from your mobile contacts), Messaging, Mail, Internet, Photos and Video, Music, Weather, Map Search, Settings, and a Program Launcher. The soft menus change contextually for each tab, and the Start Menu has large MRU icons at the top of a large-sized menu. I have skinned the basic Manilla 2D interface with a skin called Feng Shui, and added a custom Weather tab skin. It is extremely fast. Note that at the time of this writing, Manilla 2D has only been ported for HTC devices.

Some projects are just plain fun...

Wed, 26 Mar 2008 07:55:59 -0500

Back in January when I started work in earnest on the web site project I have just completed for On-the-Go Foodservice Magazine, I had to build a special development box to use because the Ektron CMS400.Net Content Management System (CMS) we had selected for this project would not install properly on Windows Vista. That's all I run here on the real hardware. It was a bit of a frustrating start in some ways. But it proved to be a minor annoyance, as I was able to satisfy every single Phase I Launch Requirement (and then some) with this CMS, ASP.Net, the afore-mentioned development workstation, and a few creative moments by your's truly. I also had more of a supporting cast of characters than I usually do contributing to the success of this project in both the graphics and web designer (CSS) fields. Special thanks must go out to Ingo Chao, an extremely gifted CSS designer, who seems to know every browser strength and weakness off the top of his head. As a result of his contribution, the site renders almost exactly the same in every CSS 2 browser in the wild. We even have print and mobile device support. I also have to thank a few special folks at Ektron (you know who you are) who back-door accelerated my requests for support on certain key 'features', knowing that we were trying to push the envelope with their product, and that the site would have some real visibility after launch.

The site launched last week (3.19.08 in the EDT afternoon to be exact) with the fewest hiccups I've ever experienced with a site launch. While there were the usual last minute panic attacks, and anxiety over things possibly forgotten or yet-to-do, I have to say it went off pretty much without a hitch. It even involved a domain transfer of the existing placeholder home page, and that only took a few hours to propagate.

What was more interesting to me was that in my 15 years of building dynamic web sites (yes, you read correctly: 15 years) on a number of different platforms, I had never hosted any of my project sites with a hosting provider on a shared server. Enter ServerSide. They came recommended from Ektron, and proved to be more than competent in working out the various configuration changes that had to be made remotely to allow the site to come up in their environment. This included helping me understand the dreaded 'Medium Trust' environment, which had a potential showstopper impact because I used the popular and awesome SubSonic OR/M for some data access I needed to do outside of the CMS. MSDN articles didn't hurt either. Anyway, ServerSide is relatively small in the world of hosting providers, but their pipe is huge and they have experience with CMS400.Net. What that also means is that the person on the other end of the support line is almost always the same person, and so you can count on not having to recite all of the background information each time you send that support request email.

But where was I? What was the subject of this post? Oh yeah, fun. Sometimes you're working along slogging through requirements and getting nowhere, and you wish you were in the Bahamas. Sometimes, on-time payment is an issue (but that's the subject of another, future post). But sometimes, you manage to work on a project that you just check off one requirement after another, the client is fully engaged and happy to have you on the team, money is not an issue (although our budget was very tight), and it all just comes together. This was one such project. For a small team of 2 full-time (customer and me) and 5 part-time (other principals, graphics, web design, etc.), I am simply in awe of what we were able to accomplish in a little over two months of intense effort. So, where's the fun in all of this you may ask? All I can say is, if you don't 'get it', you might want to consider a line of work different from web software development. If my ramblings have been too obscure, perhaps this will enlighten: the fun is in the designing, the building, the launch, and the results, all produced with the help of a great team.

Internet Explorer 8 (thank goodness it's only) Beta 1

Thu, 06 Mar 2008 18:57:18 -0600

Microsoft has released Beta 1 of Internet Explorer 8, and tonight I installed it on a VMWare Virtual Machine to test it. If you've at all attempted to conform to W3C standards, as well as achieve some Search Engine Optimization by employing Cascading Style Sheets (CSS), and especially CSS Level 2) instead of good old HTML tables, you may either be a) pleasantly surprised, or b) unpleasantly staring at the prospect of many hours of hand-editing CSS to repair to your site(s). I develop sites for a living, and I prefer a). Fortunately, Visual Studio 2008 has Intellisense for CSS style sheets.

But it turns out that there is a quick (or temporary) fix. If you have all those special CSS selectors living in your iefixes.css file (or whatever you call it!), you can continue to use them by employing a single meta tag in all of your pages (this is especially nice if you use just a few master pages for a site, and can thus place the this tag in just a few places). At any rate, add this meta tag to your <head> section:

May your time be spent productively.

Update: Here are some additional results of testing. One of my more complex layouts totally broke with the above meta tag in place. So I tried the IE8 Internet Explorer 7 Emulation button, and after restarting IE8, the site came up like it does in IE7 (and other browsers). Fine, but how am I going to convince users to hit that button? There's a built-in user training issue for Microsoft! OK, what about complete IE8 standards mode? So I set the above meta tag to IE=8, and only two elements in my complex layout broke, and not catastrophically at that. So, maybe this new world won't be so bad. But I can also see the possibility of some more conditional style sheet loading, i.e., <!--[if gte IE 8]>. Sheesh, when will it ever end? As one respected observer noted, "Hardcoding a reference to a specific browser as a necessary part of the page’s markup feels plain dirty."

Vista SP1 available for Partners and MSDN Subscribers

Thu, 14 Feb 2008 20:03:20 -0600

Vista Service Pack 1 is now available for Microsoft Partners and MSDN Subscribers. The download manager used is the Akamai torrent engine, so it comes down really fast. I had it downloaded, burned, and installed onto a test Vista Ultimate Virtual Machine within an hour and a half of finding out it was available via an MSDN Flash message. There is a combined x86 and x64 DVD image available. Everything went extremely smooth. Looks like SP1 (remember, this is a VM, so don't laugh at the performance index -- it's all constrained by the graphics emulation):

Next up will be my beautiful wife's little half-height desktop workstation, which is almost identical to the headless XP Pro/VS2008 development box I built in January (details here). And then finally will be my Vista Ultimate x64 workstation. Life is good.

There is also a Vista SP1 Clean up utility that is installed by Service Pack 1 for the really brave. Simply run vsp1cln.exe from an Admin Command Prompt to immediately remove all of the backup files saved by the update process (about 800MB). Hard disks are cheap, but wasted space is wasted space! Now if only I could find a way to remove all those Windows Updates backup files that piled up over the last year or so. It's not as easy as it was in XP, so if anyone knows of a good way to clean out all the now-useless pre-SP1 updates, just click on the old email link below and shout it out.

My new high-performance (2nd) Dev Box

Sun, 13 Jan 2008 10:17:29 -0600

I am currently working on a project that is using an (unnamed) Content Management System that refuses to install on Windows Vista, due mainly to IIS and Index Server security issues. So, I tried the Virtual Machine approach, and while that was OK, it just wasn't fast enough. And that was a 2 processor Windows Server 2003 VM with 2GB of memory. So, having built an Intel vPro® desktop system for $599 at Intel's latest Channel Partner workshop last fall, and watched my wife enjoy all of its speed running Vista Ultimate, I searched out most of the components for myself. I already had a Western Digital 74GB Raptor 10,000 RPM SATA II hard drive from my server spares drawer (add $149.99 for an OEM 74 GB drive or, better yet, $169.99 for a 150 GB drive from NewEgg, and there are frequent rebates and specials). I didn't need a monitor or keyboard/mouse because my intent was to run the new box headless over full-screen RDP from my nice 22" monitored workstation running Vista Ultimate 64-bit. Add $150 or so for a nice widescreen monitor and keyboard/mouse and you have a standalone system.

Because of the aforementioned Vista Issues, this is a Windows XP Pro SP2 (soon to be SP3) box. Here's the cost breakdown from my NewEgg WishList. This is a very sweet little box. It takes about 45 minutes to assemble if you've done any recent builds at all. Software installation takes a whole lot longer, but I already had an old XP dev box Acronis True Image disk image that I used to seed this build (but that's the subject of another post). PC Wizard 2008 reports a performance index on this build of nearly 18,000, and that's with integrated shared-memory graphics from the on-board Intel GMA3100! Plus, I was able to install Visual Studio 2008 side-by-side with Visual Studio 2005, and do my development for this project in Visual Studio 2008 with all of that CSS sweetness.

Official Patch Available for Animated Cursor Flaw

Tue, 03 Apr 2007 12:45:40 -0500

Windows Update just prompted my Windows XP Pro x64 machine to download a critical patch. This one fixes the Animated Cursors flaw, as well as six other serious issues in GDI+ that relate to the way various file formats are handled.

I'd recommend that you open Automatic Updates and check for new updates now, and restart your computer. This affects computers all the way down to Windows 2000, so if you have anyone using an older system, make sure they're patched up too.
