    Bugger,

    I am using the QSoft Ramdisk Driver for windows, allows you to specify size or allow growth and to preload an image to the ramdisk at startup and save it at shutdown.

    My 2c on Via boards. they work well for most circumstances, but do have issues with very large flash interfaces etc. I can run OziExplorer, nRoute, roadRunner playing mp3 all at the same time with no issues with lag etc. The C7 is a vast imporvement over the C3 for the same number of clock cycles!

    I noticed Millsy leaves his GPS on all the time. Can anyone tell me how to wire a single USB port on a hub to run off standby power? Is it just a simple case of splicing power into the +5v (red wire) and GND (black wire)? does the GND need to stay connnected to the Hub as well so the TX and RX (green and white) can still function?

    On all of the USB devices I have played with, the GND and the cable shield are joined together anyway, so there may be no need to leave the black wire connected to the Hub as well cos this will be achived by the cable shield anyway...

    Rodweb, with my Holux gps i just leave it plugged into the usb port with the gps on and the battery in so when the comp is in standby (I dont hibernate,just standby,have dual batteries)the gps runs off its own battery, which will last a long time, just means i dont have to wait for a cold start, also i use an external aerial, i also have a holux m1000 which i use when i use the laptop, just chuck it on the dash and use bluetooth to the lappy. i have just got hold of tiny xp and am going to play around with this and xpe to try and get a handle on this os stuff, all new to me, up till now i just chuck the xp disk in and load xp as is, i suspect a bit of frustration is headed my way

    Millsy, Just chuck the Tiny XP disk in and load it as is, will be fine. You will need to go in and play with power settings, then run the Hibernate script which Tiny installs in a folder on the desktop to get back where you are with standby and resume. Tiny leaves a lot of folders there, don't delete these in case you want them. I found out the hard way and reinstalled again! I made a TinyXP folder on my HDD with two folders a Root and a Desktop folder. Copied everything from the Root that Tiny left there into that, and put the desktop stuff in the desktop folder before I deleted anything.

    Tiny stiill supports wireless networking and bluetooth out of the box which is good.

    I think I cut the red wire on the USB and put standby power to the GPS +5v red wire with the standby negative to the negative of the Hub. So when I power down, the GPS will still stay hot.

    Still waiting for some more stuff to turn up, 4 deliveries still to come... Will post some pics then after I finish my Off road Hub enclosure with HDD, Hub and Silab Radio in it.

    Gee you guys are busy at home... I'm all tied up at work at the moment and sorting out a house extension as well...

    Anyway, if I stear clear of the Via systems, what do people recommend? I'm assuming most would head for the Pentium M based systems for temperature and power??? What about fanless?

    Bugger, one of he reasons I am trying to use a laptop is that it is a Pentium M which I read was a good choice. It still has plenty of grunt. Can't help about other ideas.

    Bugger,

    I have just upgraded to an AMD X2 4850e CPU (2.5G 45W) running in a Jetway NC62K Mini-ITX mainboard... This thing has heaps of grunt, and is not all that more expensive.

    CPU - AU$99
    MB - ~AU$200 from linitx.com

    Mainboard has onboard Nvidia GF 8200 graphics as part of the MCP78S chipset.. Also has HDMI, 6 USB 2.0 ports and VGA + DVI...

    Anyway, just an alternative to the Intel route.

    I have been thinking on this board, i would like to get everything inside a double din case and be able to get it in and out same as a normal headunit, you can get kits to fit a touchscreen and i can make any sort of case at work.
    VB-1214NM Pentium-M Nano-Gig Motherboard with on board 60w dc psu, have asked if anyone has used this board but i guess not,by the way got tiny xp working now that i am a proffesional i am going to tinker with xp embedded.
    Stupid work computer wont let me open the manage attachments bit. anyway here is the board i was looking at

    Millsy, when I played with getting minlogon going, I found I had to replace winlogon.exe in C:\WINDOWS\ServicePackFiles\i386 before I did any of the changes in the documentaton I found on MP3car. Otherwise whatever I did, the file in this folder got copied over the others. Might just make your tinkering a bit easier.

    I bought some bits for my dash here http://www.bybyte.com/ . Got a dual DIN screen fascia adapter and a screen mounting kit for a 2008 Corolla which should fit my Hilux (same radio in both cars). They turned up in about 5 days but still waiting for the screen which won't be far away to check everything for fit. If you use the board's interrnal power supply, you might consider running power through a Jaycar MP-3064 24-12 volt regulated power supply which has an input voltage range of 11-24 volts. It will cost you $70. I think my my Waeco low voltage cutout kicks in at 10.8 volts, so the 11 volt cutout should not be a drama. Might be some cheap protection.

    Hey dudes,

    I run an Apple Mini Mac running Bootcamp and XP3, FreeIce currently but going back to RR as I can not work out how to get my WebCam (reverse camera to work in FI, Sygic Drive, also playing with Destinator 7, Silabs which offer superb reception. I have an 80GB Solid State HDD and of which 45GB is allocated to XP. I have now issues with space and have currently 3 sets of maps installed.

    If all you are running is XP then even a 65GB drive would be heaps. They are coming down in price. have a look at this
