FWIW, I picked up a Jaton PCI nVidia Geforce2 (45$ shipped from newegg) card and I am able to get Powerstrip to push it @ 800x480@60 and also under Linux X can push it with the FAQ modeline. I haven't tried converting the modeline to a fb.modes style yet. In brief testing with the nVidia drivers (a TNT2 on a PC @ work), I couldn't get rivafb to push 800x480...but as I said, I haven't tried this with the geforce2 yet.

Thanks!

Thanks a gazillion minuo.
I guess that's the way to go.
I was just really hoping to get the whole thing working
without a PCI card.
Too bad.
That's life for ya.

Please explain your set more. Do you have a lilliput or Xenarc? That is the card that i am looking at to get and would like to know your progress. Please update us

antimatter-
The whole setup (so far ) is:
The system is a epia m10000 Nehemiah with a Xenarc 700TS. The card as I said before is the Jaton Geforce2 from newegg, here is a direct product link @ newegg (card). I chose this based on the fairly low price (45 shipped) and that the nv X drivers worked for a TNT2 @ work. I haven't yet tried the actual (binary only) nVidia drivers, acceleration is still low on my list of things todo (software dev starting now that the display is showing its native res.)

damageboy-
I too want to do this without a PCI card...seems a waste of my only slot considering the onboard vid is [well, should be] an excellent solution...


Small update: I tried a converted modeline (using a modeline2fb perl script I found ) but it gave me an 852x480 res...writing past the edge of the panel Maybe with some tweaking or a better way of generating the fb modeline....here's the one I used (you can see all the numbers from the powerstrip settings in it, but I don't know enough about modelines to tell whats wrong here):
X: Modeline "800x480" 31.746 800 860 940 1000* 480 508 511 525 -hsync -vsync

FB:
mode "800x480"
geometry 800 480 800 480 32
timings 31500 60 60 14 28 80 3
hsync low
vsync low
endmode


How about a new (I think, feel free to blast me with a if this has been discussed before) thought thrown out for anyone's comment/shootdown/compliment/....:

When I redid the BIOS image I made an 800x480 tif, then I resized(image, not canvas) to 640x480 (squished looking on my pb). Works perfectly in that the PC boots and the Xenarc stretches the 640 to 800 and the image is not squished anymore. Now, a couple minutes ago I tried a little SDL test with the same squished style of image as a background using a 640x480 vesa FB. Again, Xenarc stretched it and all seems good. My thoughts go like this: If you "squish" all the carpc frontend images by the same ratio as the bg (640/800=.8), they all should be stretched by the xenarc without any issue. As for text being off kilter, shouldn't the same stretching apply to a bitmapped font? The screen would still show 640x480 is the OSD, but I don't really care so long as the text is readable and the aspect ratio is clean (ie, it looks good ) One thing I'm not sure about would be mapping the coordinates for the touchscreen (buttons, etc.)

This probably wouldn't help users of MediaCar/FP/whatever without at least some new skins and maybe some dev changes, but devs that are rolling their own should be able to make this work, or am I missing something? I will be playing with this some in the next 24 days (newegg return is valid for 30 ), and see where I get, but I wanted to throw the thought out so I can get a "yeah, that would work" or a "no, you're being dumb and forgetting <whatever>" from someone who may know more about this kind of stuff than I.

Wait... Your screen reports 852x480 using the onboard VGA on the VIA...
and the X Display server thinks there are 800 Pixels wide or 852?
Try "xdpyinfo | grep dimensions" to see what X "understood"

Sorry for not being clear, this was still with the nVidia card (geforce2) and it was using the framebuffer. I took the modeline from xenarc's www and used a modeline2fb script to convert it to a fb.modes style and added it to the file. Then I modprobe rivafb and fbset 800x480. The OSD reported 852x480 and had the left edge lined up with the left of the panel, but a ls /dev showed that it was drawing text off of the right edge of the panel. I'm not sure why, maybe someone else knows more about how fb modelines and this panel work?

As for X, the xenarc modeline works great with this card and the OSD reports 800x480@60.

Anyone test this with the lilliput? and when you say as for X. WHat do you mean?

All of this modline2fb and fb.modes styles are greek to me.

Thanks for your input

Using Linux there are two ways for graphics, the framebuffer or X. X is the "normal" way that most users would use to get a desktop for general use, but it is another part of the system to wait for startup. The framebuffer doesn't (natively) support windowing or any of the desktop-use style features, but could display a fullscreen app perfectly and start quicker.

Each system has its own way of specifying timings for video modes, X uses a Modeline setting in its config file, framebuffer uses the fb.modes file with its own format for timings. The modeline2fb I have referred to is a perl script that converts an X Modeline setting to a fb.modes style. I still think it is likely possible, with some playing with timings, to get 800x480@60 on the framebuffer with this geforce2 (after all, if X can do it, it proves it is possible, just need to find the right timings).

In my reply to damageboy, I meant that I haven't been successful getting an 800x480 on the framebuffer, but X is working just fine (even the OSD).

FWIW antimatter, I did try this card briefly using powerstrip and it worked fine with XPProSP2. I don't have a lilli though, so I can't help there.

Well holy crap, no wonder why i had no clue on what you were talking about.... Linux. Why didn't you say something before (maybe you did) *goes to look*

Thanks for clearing things up and for your long explaination

When you say "It worked fine with XPProSP2" can you be more specific. Did you mean that it displayed 800x480 fine on the resolution and on the OSD?

Heh, sorry I don't think I mentioned it as I was initially replying to damageboy about X modelines

For XP SP2 (I had it one there while I was messing with BIOS tools to flash a new logo), I used a demo powerstrip and IIRC I went to some sort of a 'All Resolutions' or 'All Modes' and chose the 800x480 that was listed there. I think this gave me 800x600 on the OSD, so I clicked the icon that looked a bit like: --><-- (for shrinking horizontally) and it popped back with 800x480@61 on the OSD. I then toyed with the timings (I believe the vertical timings weren't quite where the xenarc FAQ showed them) and got it to 800x480@60 on the OSD. I wish I had taken some screenshots...if I get a chance this weekend I'll put XP back on and get some to post.

With those settings, the boot is a little wierd, but I suppose one could live with it. It would give me a 720x480 (or 400...don't remember exactly) during the XP loading screen and it would be "goofy" looking until powerstrip started up. Once PS was running the card would output 800x480 and the screen would self-adjust. It seems like I've read that you can "save" a custom resolution from powerstrip and have it available to windows natively? I don't know much about that...not a windows guy

Cool man, thanks for the information. I have been eyeing that graphics card for a while and i think it may be time to give it a go. I just don't want to buy the card and not get the native resolution.

If any one with a lilliput has changed their resolution to 800x480 and gotten the OSD to recognize it as 800x480 please let me know what your setup is like and what you did to get it that way. I too am on the quest for 800x480

My 700tsv always detects 800x600 as 800x480, so i just let it cut the lower part of the screen, and then display FrodoPlayer on the displayed part... =P Thats my solution =)

New BIOS Version

Hi,
Although currently the "newer" BIOS 1.16 seems to be a ****ed up it is claimed that it might support Widescreen VGA.
I'll be glad to know if someone can make it work.
