Testing is one of the most important steps in putting a computer in your vehicle or car and is often skipped. We highly recommend testing your system on the bench for a day or two before you put the device in your car. We previously did a video on how to build your own car computer. This video will give you some insights into this next step.

Rob Wray from mp3Car takes a closer look at Intel's D945gsejt motherboard and their SSD z-u130 2 GB module .
The unique fact here is that they made room on motherboard to fit this 2gb module into the USB header, so you can essentially have a very fast boot up time if your OS is installed on that chip without taking up barely 2 inches of the board.

Some forum members were already talking about this mobo but I thought I would shine some light on the subject. I had a chance to play a little bit with it and see if it's working etc.
Form factor Mini-ITX /micro-ATX compatible
Processor Integrated Intel® Atom™ processor 330 with a 533 MHz system bus
* One 240-pin DDR2 SDRAM Dual Inline Memory Module (DIMM) sockets
* Support for DDR2 533/667 MHz DIMMs
* Support for up to 2 GBΣ of system memory
Chipset Intel® 945GC Express Chipset and
Intel® I/O Controller Hub 7 (ICH7)
* Eight USB 2.0 ports
* Two Serial SATA ports (3.0 GB/s)
* One parallel ATA IDE interface with UDMA 33, ATA-66/100 support
* One serial port
* One parallel port
* PS/2* keyboard and mouse ports
I tested this board with the following config:
- 80 gig seagate SATA hdd
- 300 w power supply
- 2g of DDR2 800MHz Buffalo ram (1 stick)
- Dell mouse and keyboard (both usb)
- memorex external DVD via usb
The board was able to install XP Home flawlessly, and so far, is very quick. Startup time 46.8 seconds and shutdown time was 8.5 seconds.
You can't look at this board without comparing it to the previous LF2 model.
Unfortunately the only thing I was able to find, along with others here on the forum, the S-Video is the only difference. The previous model has it and is priced on newegg for 79.99 and this model doesn't have priced at 76.99 on newegg.
So it seems for $3 less you can get a board without S-Video. Why not include DVI or display port on the next model?
Talk about this, and see other pictures on our forums

We talk with Robert Allshouse, Business Development manager of Intel's NAND group. He talks about Intel's SSDs which are now hitting mass production. The products are guaranteed to work from 0c-70c. They use less power and take far more of a beating than their disk counterparts. Just get ready to unload your wallet.
Transcript:
Rob Wray: Hi, my name’s Rob from MP3 Car. We’re here at CES 2009 at Intel’s booth, and Rob from Intel is here with us giving us a quick demo of some of their memory that’s been in the press recently. So you’ve got three different modules of memory here which are all very interesting.
So this guy here, he’s an eighty gigabyte module that sells for what? About $500 on New Egg? This guy’s about, is $1,000, and how ––
Intel’s Robert Allshouse: That’s 160 gigabyte. And this little one down here is another eighty gigabyte. It’s the same drive in a slightly smaller form factor for your more small form factor net tops and other smaller applications.
Rob Wray: Okay.
Intel’s Robert Allshouse: Using a micro static connector instead of the standard static.
Rob Wray: So how long do these last?
Intel’s Robert Allshouse: The typical life for the consumer level drives is they’re expected a five-year useful life, and that useful life is at a ten-gigabyte write per day.
Rob Wray: Right.
Intel’s Robert Allshouse: So since the technology has finite write cycles. You can read as much as you want, so it’s a read-intensive application. By continually reading maps from there, you’re not affecting the life.
Rob Wray: Right. So you were telling me a little bit before about multilevel drives. So the multilevel drives, you can write two bits of data per transistor, and the single level drives you can write one bit of data per transistor. So it sounded to me like most of our readers are really going to be interested in the multilevel, because you get the same read performance off the multilevel versus the single level, and just your write performance is degraded, and it sounds like with five years writing ten gigs a day, the MLC is going to capture everybody unless you’re trying to run a database server or something with tons of writes.
Intel’s Robert Allshouse: That’s right. The SLC drives, our thirty-two and sixty-four gigabyte drives, at near the same price points, are really focused on those sequel server guys with high write intensive applications. The five-year useful life for these drives is for most consumers plenty, and it’s actually more than enough. The difference in the writes as you were saying, it’s about seventy megabytes per second write on the MLC drive. And it’s 150 megabytes per second write on the SLC drive.
Rob Wray: Right.
Intel’s Robert Allshouse: The reads are about the same. They both flood the SATA bus at about 250 megabytes per second in reading. So you’re read performance between the consumer level and the enterprise level drive are the same.
Rob Wray: We were also talking about boot times. So boot times you said was one of the least impressive benefits out of flash, but a lot of people that we work with decide to resume from hibernate, and since that’s just a read application we should get a pretty good boost and resume from hibernate, but not boost – booting.
Intel’s Robert Allshouse: Yeah, you definitely – I mean, you see definite improvements in your boost. You know, five, ten seconds. But a lot of what’s happening, if you go look at a boot demo side by side, you’ll see the IO light is not flashing as much because it’s going so much faster, but you’re still waiting. And there are a lot of other things that happen during boot besides just IO.
I’m less impressed by that as much as something like hibernate, or really application load performance. Because application load where you’re random IO performance shows the huge difference, and you’ll see a demo on that where you can see you know, files transferring and applications loading immediately in real time.
Rob Wray: Well, let’s get into that demo.
Intel’s Robert Allshouse: Alright. So the primary purpose of this demo is to show how while file transfers are happening in large applications, you don’t slow down the rest of your system. So right now we’re copying a 680-meg set of files, at the same time we’re going to open up Picasso, look at six large pictures, create a collage, and then choose another IO-intensive application like opening up iTunes, which then looks in your folders, sees if there are new songs to look for, all while that’s happening. And this takes about thirty seconds before the collage is done, and playing.
Rob Wray: So the CES show floor is loaded with tons of vendors, probably hundreds of vendors, trying to sell you memory for your laptop. What’s the difference between stuff that would go in an inexpensive laptop or it’s floating all around the halls versus what we see here?
Intel’s Robert Allshouse: So there definitely is a big difference, and they’re all based on the same NAN technology with the exception of MLC and SLC, but really underlying it is NAN. But what you do for say additional camera where you’re writing maybe a couple hundred times maximum in the life of the drive, and you’re writing at the speed of moving a five-megapixel image or maybe even high def video at thirty megabytes per second, it’s different than what you’re trying to do on a laptop. And so you do have different rates.
The most simple grade would be a USB or an SD card, and those are designed around consumers who are just moving small amounts of data rarely. You’re not using it all day, every day. And then you move to your net top, net book type design, where it’s still small density and it’s off-the-shelf components building a small density low cost SSD. And at the high end, you have some drives like this one that have architecture design and route very high performance. Ten channels and parallel operating versus maybe two or four in the lower end drives for net book type applications.
Rob Wray: Right. So the other thing you guys have done, you were telling me before is you’ve written some – in your controllers, you’ve written things to optimize the write processes so it’s faster. You have more DRAM and things like that that you wouldn’t see in consumer grade.
Intel’s Robert Allshouse: Absolutely. A problem inherent in technology behind these is you can’t write a single bit, and so what you may run into is depending on how a vendor writes their algorithms, they may have to do two, four, ten times the amount of writes to change the amount of data they want to change. We’ve optimized that to get down to about 1.1 times. The term’s called write amplification. So it says that if you’re at two times versus one time, you’re getting half useful life. We’re only doing about 10% extra writes and we’re best in class in the industry.
Rob Wray: That’s great. Well, thanks for taking the time to give us such a thorough interview.
Intel’s Robert Allshouse: My pleasure. Thank you, Rob.

Dashtop Devices has a demo car here at CES. Here is another example of a car computer hitting the market.

My name is Robert Wray. AKA Fiberoptic on our forums. This nic goes way back to the original days of MP3Car when I had a super speedy uncapped 10mb cable modem in 1996 and nobody else was on the Comcast pipe. For the last 4 years MP3Car has consumed an average of 70-80 hours a week of my time. Before MP3Car became my life I worked at a small technology consulting company. I scoured the net for travel bargains, toured the United States and 12 other countries. I sailed on friend’s boats, rock climbed, and enjoyed the outdoors.
   
Most of my work days at MP3Car consist of reading and replying to sales questions, reading the forums, testing new products and filling in where ever the rest of the team needs help. Currently we have two lab cars that we test things in. The original Toyota Highlander Hybrid which we used with Intel @ CES 2006 and a 2006 Scion TC(prototype dash photo below). My desk is also normally an explosion of technical parts, paperwork, projects, test equipment and ideas in progress.

Recent public reviews of products I have tested are the SIIG , M4 ATX software and the Garmin Mobile PC.
Expect more of these reviews on a regular on a basis as part of our blog.
Many of you may have noticed that MP3Car has been undergoing changes over the last 6 months. One of the biggest changes here is the separation from our StreetDeck product which occurred in mid July. This separation will allow us to support all software efforts as well as redirect resources towards the growth of the community which has grown to 1.1 million posts and 101,000 global users.
We hope to roll out several community upgrades before the end of the year. I believe one of the most important things we are doing is creating this new blog. A blog is the first of many infrastructure improvements that will allow us to more openly share information about the growth of MP3Car and exciting new things happening in mobile computing.
All of the MP3Car team will be contributing to the blog on a regular basis as well as an occasional guest blogger. If you any ideas that you think should go on the blog, please send me an e-mail.
Discussion about the MP3Car Blog will occur in this new forum which has been created here.

Intel notes that the versatility of the SwitchBack-PC is nearly “boundless,” and the modularity of the Black Diamond solution creates a lot of optionsvfor the design of the chopper. “Instead of a computerized dashboard affixed permanently to the bike we can use the BackPack technology to make it portable,” explains Intel’s Reed. “So theSwitchBack-PC not only controls and monitors the chopper, and integrates with its electronic subsystems, but it also functions as an Ultra Mobile PC, allowing the user to surf the Internet, do email, write reports, and so forth. You can snap it off and take it with you, preventing any unauthorized person from operating the vehicle.”
But it’s not just a snap-on PC either. “Everything on the bike is integrated with the computing system, and vice versa,” explains Justin Dyster, president of Black Diamond. What that means is that the ignition system is controlled by fingerprint recognition software. The sunlight viewable digital dashboard displays all of the traditional vehicle indicators like speedometer, tachometer, fuel and oil gauges, battery life, and turn signals. Black Diamond used StreetDeck* infotainment software to integrate audio and video applications like GPS navigation, Wi-Fi connectivity for quick updates on traffic and web-surfing, and touch-screen access to the radio and MP3 files, all of which are also integrated with the handlebars and headset in the helmet. Rear-mounted USB cameras replace standard rear-view mirrors to display rear-view images on the digital dashboard. This “dashboard” is also a fully functional PC, complete with QWERTY keyboard that can be disconnected from the vehicle and taken with you, to create, edit and view presentations, spreadsheets, do email, and so forth.
Dyster also notes that the SwitchBack-PC used on the Intel Chopper is just like the off-the-shelf version that Black Diamond makes for other applications, with a few minor differences. “We used a custom paint scheme, and we increased the performance of the SwitchBack with the new Intel® Core™ Duo processor to allow for more features.” Battery life of the SwitchBack-PC has been extended in several ways. Besides the engineering efficiencies that give the device a long battery life to begin with, hot swap capabilities allows the user to replace the battery on the go. Plus, the SwitchBack-PC battery will be recharged while the bike is operating. So the user will always start with a fully charged battery when the UMPC is detached from the vehicle.
