Here I site rebuilding.....

Well I thought I just had to have a dual boot system! And now here I sit reloading the CF-28!
Oh well, I gave it all I had.
All seemed to go well until the end, for no apparent reason, Windows decided not to boot anymore.
XP trying to load UBUNTU, partitioning went fine, then while loading UBUNTU it just quit, left it sit and sit and sit and nothing. I am wondering if the CD drive quit reading.
Anyway I spent enough time trying to restore, time to reload!
I left an unused 10gig partition on the HDD to try again another day.

What did you have as a boot loader? How did the install go, or did it even complete? Can you give us a little more detail as to how you started the install, what directions you were following?

(too many questions...... )

 

Did not complete the install, I think thats when it all went south. Was following on screen directions. The partitioning went fine, it was during the install that it failed.
Downloaded UBUNTU and booted from that CD and followed on screen directions.

Try using the slimed down version of ubuntu

 

Rick - I had the same problem - Ubuntu just stopped loading - I found a fix for this on the Ubuntu forum but it was after I already re installed so I dont know if it would have fixed it but I will try to find it and link it for you. Also is your HD new? dual boot is tough on older slower HD's for some reason. Will post back with more info - don't give up it's well worth it.

 

Ok will watch for link.
Yes 7200 rpm 100 gig new.
Also lost my GPS not sure if its related... was working when I reloaded XP then quit.

Rick
Read through this - not sure if it will help but sounds like it is good info even if nothing else -
http://ubuntuforums.org/showthread.php?t=24113&highlight=grub+restore
I will keep looking -

 

Also - My first attempt at Linux was with a unit that had OEM GPS and it gave me a fit - I had to unhook the GPS while loading linux and then had issues with it even after that - this was on an 800 - my 1G does not seam to mind the OEM GPS.

 

I went into BIOS and turned off then on then to auto, changed resources, never made any diff.
I pulled it and will let it site over night to see if the power dissipates from the caps in it. If that does not work I will replace it.

Only thing left to figure out on the recovery is getting CalWin to work. Touchscreen works but is off by about .5" and I can not get the calibration program to respond to my touch, no matter what I use, finger or stylist [sp].
Will download new and try that.
Rick H...

 

Remember to press and hold on the calibration - till the spot moves on it's own? I made the mistake of just tapping the screen (stupid me - like on my iPaq). The 12.1" screen was fine that way, but the 13.3 wanted to be set correctly.

Didn't realize what I did wrong until someone else brought it up in another thread.

 

Out of curiosity... Will this calibration correct my I-Guidance? When I use it for street navigation and I tell it to take me back to my house... It wants to take me about 5 more houses down the street. Do you think that is I-Guidance or the calibration of the GPS engine?

 

I always assumed accuracy was a function of the GPS engine. More sats better accuracy.
Thats my own assumption.
I did notice that the 408 seemed to show a 1 mph speed in Streets and Trips even sitting still. My Garmin Street Pilot does not do that.
Rick H...

 

I don'[t see what possible affect the touchscreen calibration would have on the GPS accuracy.

 

I agree on that. Just took a short trip with mine, worked excellent. No false MPH readings and always showed me on the road, not running the ditch (which I have been know to do!).
I am pleased.
On a side, on the 25 mile round trip I had net stumbler running. Logged over 60 wifis. Dang I can not believe how many people have them running wide open with no security!
Rick H...

 

I don't either... That was not what I was talking about. Someone mentioned using a program to calibrate the GPS engine. My question was does I-Guidance have my address wrong or does my GPS need calibration oof some sort? My Hummer also is slightly off on my house number. So is my wife's Bimmer...

Edit: Sorry... Thought you were talking to me....

 

TB, I'm betting on the mapping program software being slightly off. If you are familiar with benchmarks, find one near you for which you have a good topo map. Pull the lat/long off of the map at the benchmark with as much accuracy as you can. Compare that with the lat/long on your various GPSs.

Benchmarks are surveyed as to position on the Earth as opposed to being marked via sattelite. Not foolproof, but should be pretty exact.

The other oddity about GPS software is that they can be spot on when at one scale; and when you zoom in and out, it seems as if that changes.

Just some random rambling of an old codger, hope it helps.

 

The accuracy of your house location on I Guidance is totally a function of the map as loaded into I Guidance. You have two issues here, software accuracy and gps accuracy. If your gps always reported your location to the software exactly the same, your address would always be in exactly the same location, not necessarily where it really is, but always in the same place. GPS accuracy is variable within certain limits depending on hardware, weather, interference, and even intentional government degradation of the gps satellite signal, although they don't seem to do that any more. Any Sirf III reciever, at least those from USGlobalsat will give you very good accuracy if it has good antennas and a good view of the sky. They give pretty good accuracy even without a good look at the sky. A really good DGPS will give you consistent sub-meter accuracy. They cost anywhere from $5000 up. USGlobalsat units, in my experience will often run at 3 meters or less, and that is very good for a $50 gps. The only way to really see how accurate your gps is is to compare the location it is reporting to a very good gps, or better, find a USGS monument, let your gps settle down, and compare the latitude and longitude you observe on your gps to the known location of the monument. The only interesting comparison is between known geographical locations as the accuracy on the map which has been scanned into a software program may vary a lot even though your gps is giving the computer a really good fix. Somewhat ot I know, but I have seen a lot of nonsense about gps accuracy thrown around on places like eBay lately. Edit: On my very good GPS's I have control over more parameters than you can imagine, but I have never seen one that would allow a user to adjust the position being reported.

 

Never thought about software accuracy and now that I do, I am betting its more in error than the GPS engine.
The only difference between men and boys is the price of their toys!
Thanks for the great insite.

I guess that's why all consumer grade mapping software has the big disclaimer when you use the routing; "DO NOT USE THIS SOFTWARE AS A PRIMARY SOURCE OF NAVIGATION" or words to that affect.

 

Even though some marine GPS mapping programs are now legal for sole means of navigation; the vendor of the programs still give the caveat about the use of paper charts. May be CYA on the part of the vendor, but in my experience it's very sound advice.

 

Pappy, That is precisely why you have observed the position jump when you zoom in and out.
"The other oddity about GPS software is that they can be spot on when at one scale; and when you zoom in and out, it seems as if that changes."
Obviously the different zoom levels are using different scanned maps for more or less detail and the maps are different in their relationship to real world position. OZI requires you to tag a known point, real world, to gps location to align your uploaded map to your gps. This is what TB was asking about but I doubt I-Guidance has a way to do that. My "toys" are anything but, I really need sub-meter accuracy in my daily work. REAL accuracy is a Leica unit I got to use once, $80K+. It took 3 1/2 hours time to first fix, accuracy within 1/100th of a foot, VDOP and HDOP. That's less than 1/8 of an inch.
