Nvidia 8800GTX no 1920x1200 boot size
« on: July 16, 2010, 07:40:47 PM »
hi guys,
how many of you have an Nvidia 8800GTX that can't do 1920x1200 under vesa 3.0? Well I guess I have one. I used the video output display from the boot loader and I think the highest I ever got was 1280x1024x32.
I use a DVI output and have it connected to the port closest to the motherboard.
I'm sure this card is capable of more. THe VESA information is stored in the Video Card BIOS I believe.

Not sure it it helps you at all, but I can tell you my 8800 GT does 1920x1200x32 in Chameleon all right. I'd be surprised if they (Nvidia) dropped that for the GTS.

which version of Chameleon are you using? Did you patch your vbios in the video card? Thanks..

Nothing related to Chameleon, you have to blame on your BIOS.

I did had the same issue as you, but after updating my 8800 GTS 640 bios I've got 1920x1200 support ;)

Ok, so, it took me some time but I'm finally booting with 1680x1050 resolution.
Card: PNY 8800GTX OC Edition
Bios: Modified EVGA 8800GTX v10

I matched the vendor sub id, board id and applied the same clock settings that the PNY OC edition had used.  Also removed the EVGA bios screen so I can get right to my nice Gigabyte bios without seeing info about the video card first.

Here's a video.  Ignore my goofy laugh when I realize it's working.   8)

Ok, it's basically 5am. I need to get to bed.


Edit: Just for the record, here's my original post: http://forum.voodooprojects.org/index.php/topic,945.msg4076.html#msg4076
So glad this is fixed!  Not a Chameleon issue at all, but thanks for the help here guys!

nikey22, if you need a little tutorial from me, I'll run you through what I did.  No promises, this is a risky fix, but it worked for me :D

I'm also interested in getting 1920x1080 for my Gigabyte GTS250 card (GV-N250OC-1GI Rev 2.0). I think i should visit mvktech.com :)

zef, you'll have to get lucky and find a GTS250 that has 1920x1080 VESA support.  I'm trying to find if your card sticks to the nvidia reference design.  If it does, you'll have a lot easier time finding a compatible bios (you should be able to use any manufacturer's bios that uses the reference design).  I figured it's worth having nikey22 get instructions from me since we have the same card.


Edit
Wow, this is interesting stuff.  Try this instead if you're feeling up to the risk. If you'd like to actually modify your existing bios, I think that is possible too.  http://www.insanelymac.com/forum/index.php?s=&showtopic=211294&view=findpost&p=1416376

Also, we have a thread on this here too.  http://forum.voodooprojects.org/index.php/topic,1227.0.html  Not for actually flashing your bios, but a diff for chameleon :D

I was working on a PM on how to do this, and decided I should probably post it up in case anyone else wants to give it a shot.  I'm sure I'm doing plenty of things the hard way, but this worked for me.

DO THIS AT YOUR OWN RISK

Go get:
NiBiTor 5.6 http://www.softpedia.com/get/Tweak/Video-Tweak/NVIDIA-BIOS-Editor.shtml
nvFlash http://www.softpedia.com/get/Tweak/Video-Tweak/nVFlash.shtml
USB flash drive
FreeDOS usb image http://derek.chezmarcotte.ca/wp-content/uploads/2009/08/FreeDOS-1.0-USB-Boot.img.bz2
An updated bios for your card that includes the resolution you want.  Your best bet may be to just get the most recent bios (or modify it using the instructions here: http://www.insanelymac.com/forum/index.php?s=&showtopic=211294&view=findpost&p=1416376 )

I used NiBiTor 5.6 to modify the EVGA 8800GTX v10 bios.

Fire up NiBiTor
Before doing anything else read in the bios from your card, then back it up
Tools -> Read BIOS -> Select Device -> Pick your card.
Then Tools -> Read BIOS -> Read into File...  And save it someplace safe.  Then make a backup copy

Now, Tools -> Read BIOS -> Read into NiBiTor and we can start looking at your bios info.

After this, open a second copy of NiBiTor to edit the donor bios.  Go to the Adv. Info and match your Sub Vendor ID, Sub System ID, and Board ID.  Your Device ID should probably already match.  There might be something wrong if it doesn't.

I went through the tabs and matched up the clock speeds as well (I only matched my clock speeds because I had and OC edition card - most cards would ship with stock speeds so you probably won't need to modify these).

I also went to the Boot Settings tab and unchecked the Display Boot Messages box because I was tired of seeing this before my mobo bios.  This is optional (obviously).

One note: Just above the tabs in NiBiTor, you'll see your Product: info.  My stock bios says G80 Board - 0355h00, the bios I flashed with says G80 Board - 0355h05.  I had no problems, but this worried me more than anything else.  Lesson learned; it's at least ok for these to not match up sometimes.



Once you're done modifying the bios, unzip the FreeDOS image, then dd it onto your usb key (it will erase everything you have on your key)
SAMPLE dd command from OS X (modify for your actual file location and your disk):
Code: [Select]
sudo dd if=FreeDOS-1.0-USB-Boot.img of=/dev/disk10 bs=4096
Now mount your USB key (OS X does this for you) and drag in your modified bios (and a backup of the original in case something goes wrong).
Also copy over the nvFlash utility.

Now reboot and boot from the FreeDOS disk.  use
Code: [Select]
nvflash newbios.rom  to flash your bios.  If there's some mismatch, you may need to use
Code: [Select]
nvflash -4 -5 -6 newbios.rom to force the flash  (I had to force the flash).


Edit: Added a couple more code tags for easier reading

I have a spare 8600GT laying around now.  I might see if I can learn a little about flashing new resolutions onto an existing bios.

zef, if you can let me know what's going on with this Chameleon patch: http://forum.voodooprojects.org/index.php/topic,1227.0.html
I'd be very curious to find out if it might be included.

Would be great! Investigating the case :)

Terc, your suggestions to update the bios worked perfectly.
I now have bios 60.80.13.00.13, which is the latest bios for the EVGA 8800GTX 768mb card and this bios correctly unlocks the extra native resolutions, I now have 1900 x 1200. The icons are slightly stretched though, so I used GIMP and resized each of the icons from 96x96 to 96x81, and they seem fine.

great suggestion!
case closed

nikey22, one last thing.  Go into your theme and change the resolution to 1920x1200  (set the correct height and width)  That should get you the right icon dimensions.  I'm not sure there is such thing as 1900x1200, and overlooking the theme resolution is easy to do.

Glad to hear the bios update did the trick though!
