Information on VESA modes in ATI&NVIDIA bios

[colorfuel]

Yes, it would display the full resolution. New Chameleon RC5 build has the module Resolution.dylib, so flashing the GPU's BIOS isn't needed anymore.

 

 

Ok, so how do I get the boot menu to show up in 1680x1050?

 

It seems my 6870 VESA only supports 4:3 resolutions, resulting in 1400x1050 max resolution for my monitor.

 

 

Note: Once booted, any resolution works properly.

You added some resolutions (1680x1050 and 1440x900) that were already present so they will have no effect. And 1920x1080 is not a standard VESA resolution so it might not work.

 

However, the real problem might be that any resolution above 1280x1024 is being blocked no matter what you have in the tables. This seems to be the case with my 9800GT. A few posts back, I posted a link to a site that showed how to unblock those modes. I just can't find the proper offsets in my BIOS to try it.

 

In the mean time, you can try this solution: http://www.insanelymac.com/forum/index.php...=255510&hl=

Thanks. Only thing I can't figure out is if my 560Ti should be able to support VESA 1680x1050? I don't know how to find out. If I can boot into the OS and after the bootloader screens it is fine then I didn't know what approach I should take. Kind of a noob at hacking the BIOS (my specs are below in my signature if it depends on my motherboard)

How can I put 1920x1080 in vbios tables?

Same here with EVGA GTX460 SC. Nothing changed after flash.

[smsaim]

Same here with EVGA GTX460 SC. Nothing changed after flash.

 

Same here, no change after Hex edit and flash. 100% sure I edited as per instructions, and flashed successfully too.

[colorfuel]

This is my dilemma as well. Hopefully someone can figure out how to fix this...

 

I found a solution.

 

I installed one of the later chameleon updates (with icloud support) and put the file Resolution.dylib inside /extra/modules

 

and of course the

 

<key>Graphics Mode</key>

<string>1680x1050x32</string>

 

line in boot plist.

 

 

hope that helps you aswell.

I have just done this mod on my ASUS 5870 and it works!

 

My card is an Asus EAH5870/G/2DIS/1GD5 connected via dvi to a dell 2407. I wanted 1920x1200 for chameleons gui as I used to have this with my gtx285 using the anval booter. Since I am now using chameleon 2.1 r1650 for Lion the game has changed!

 

 

The instructions are perhaps a little scarce in the original post for ATI owners so below is a picture guide as to what I did. I will also attach the stock & modified bios so you can compare what I did.

 

 

1:

 

Get your bios from your 5870 using gpuz in windows.

 

 

2:

 

run analysevbios on it and you should get 5 'modes' shown similar to the screen shot below. We have to edit all of them.

 

 

write down the hex of the 5 tables, i.e. a9ee, aa0a etc.

 

 

3:

 

Open your extracted bios using RBE 'radeon bios editor'. Click the hex dump button.

 

Now on the right in the 'jump to pos' field type in the hex value of your first table and click go!

 

it'l jump and you will see the 6byte value on the left 20 03 00 01 58 02 exactly like in DieBuche's post. Highlighted in pic Below.

 

 

 

4: Changing the modes to 1920x1200 resolution.

 

 

Mode 1 (a9ee)

 

Now we are not interested in the bytes 3&4 of that string. This is the case for every table. So the first edit I change 20 03 00 01 58 02 to 80 07 00 01 B0 04. We change bytes 1&2 & 5&6, leaving bytes 3&4 as they were.

 

Mode 2 (aa0a)

 

Lets jump to position aa0a in RBE. Look at the bytes and you'll see almost the same as before except bytes 3&4 in the middle are different. Edit bytes 1&2 & 5&6 to the same as you did before. So 20 03 E0 00 58 02 becomes 80 07 E0 00 B0 04.

 

 

Do this for the remaining 3 modes.

 

 

5:

 

Lets click on 'okay (applies changes)' in RBE and make sure the checkbox 'automatic checksum handling' is ticked.

 

Now save the modified bios out of RBE. I called mine mod.rom for ease.

 

 

6:

 

Lets run analysevbios on the modified rom. Now what should actually happen is that it will show no 'modes' found. See my screenshot.

 

 

What is happening is analysevbios is searching for modes that are 800x600. We have just changed those modes to 1920x1200 so of course it will show nothing found because there is no longer 800x600!!!

 

That's it now - just got to flash the bios.

 

 

Flashing the bios.

 

I used the latest atiflash on a win98 bootable usb drive. You should experiment first - I created a bootable usb dos drive. Now I had to flash my bios with 'atiflash -f -p 0 mod.rom' I was planning to use the -pa flag which is supposed to flash all adaptors in the system without question - However it fails for me and demands I choose the adaptor number. atiflash -i tells me my adaptor is 0.

 

So knowing the right flash command i created a second bootable usb drive with my unmodified bios on. This was my blindflash failsafe. I put 'atiflash -reboot -f -p 0 stock.rom' into auto exec.bat. The reboot flag tells it to reboot after flashing so I know its finished.

 

Lastly on my gigabyte ex58-ud5, it seems to have an issue booting of usb reliably. To make sure the blind flash was gonna work I unplugged my regular hard drives and set the first boot drive to be 'usb-hdd' This ensures it will boot from the usb no matter what.

 

Enjoy!

Hi Dublove, thank you so much for detailed guide, I hope that should help many hackintoshers out there. I am trying to add 1920x1080 vesa mode to my Gigabyte HD5750 but I am stuck on step 2 (analysing vbios). when I execute the commad in terminal, all I get is info about lenth. I dont get any info on modes. I have tried many ways but same results. I am doing it on Lion, may be that is the reason.

 

I have attached my vbios and would really appreciate if you could analyse it on your system and tell me what are the 5 modes (eg: A9EE) for my bios. I can do the rest. Note: there are two bioses in bioses folder, one extracted via gpuz and one via winflash.

 

Once again, thank you so much for doing it for our hackintosh community.

Hey

I read from a successful mod of the HD6850, but the tool from the first post isn't working for me and just shows the lenght but not the exact position of the resolutions.

Has somebody a solution? I tried different bios from different manufactures (XFX, Sapphire, Club3D, AMD, ...)

Awesome guide, Thank you!!!!!

 

Hey guys,

 

Which part do I have to change to get 2560x1440x32 for a ATI sapphire 5770?

I already made the patch for 1920x1080x32...

 

 

 

Thanks and best regards

Len

anyone?

Thanks to dublove i was finally able to hard flash my MSi ATi HD 5870, i can get now 1920 x 1080, but i still have those 1 inch thick, awful borders. Does anyone know, how to remove them?

 

I have the same problem, with an HD 4850. I noticed the resolution did change, because during boot there were some lines that wouldn't fit in one line and now it does.

Besides, in case of any problem with my monitor, I believe it would be safer to have 800x600 mode. I guess it'd be better to replace another "less useful" resolution, perhaps 1152x864. How can I do that?

 

Edit: another reason, look what happened to my BIOS screen (previously, it was fullscreen, almost full, with the same black borders).

 

Edit2: I managed to replace 1600x1200 with 1920x1080, so BIOS went back to normal, but I still have those borders.

Well Guilherme, I don't know if DieBuche is still around. But it looks like that we are yet to find someone who could post screenshots of Chameleon boot screen which does not have the blackborders. Since you claimed that you were able to change the resolution, did you also try to set the resolution in the theme.plist file in your theme folder?

Okay, I've tried following the tutorial in the first post, but I just don't get it.

 

I'm running a 1GB ASUS GTX 460 with the stock BIOS, and I want to edit it it so that I can use 1920x1080x32@60Hz. When running the included program I get:

 

Attempting to open stock.rom

Length:60928

Found 1. possible NVIDIA mode at 0x418d(Decimal:16781)

Empty Table at 42ad(Decimal:17069)

Empty Table at 432d(Decimal:17197)

Empty Table at 436d(Decimal:17261)

Correct number of finds

Mod should be working

 

So I opened the .rom file in NiBiTor and went to the HexEdit function, then went to 0x418d and it was just 00 00 - I don't get what I'm trying to find here?

 

Also, how to I actually edit the file?

 

If anyone could give me quick step-by-step instructions on how to add a 1920x1080 VESA mode to my 460's BIOS, I'd really appreciate it. Thanks

I tried it with my 460 as well and it didn't work. The entry was there and I made a couple of edits but still no 1680x1050 on boot. Some say it doesn't work on nVidia cards if you use DVI but I had it working fine on my old 8800GT with DVI and I didn't have to make any rom edits.

What I don't get is what I even need to do to try it out. I figure that even if others aren't reporting success, it's worth having a go, but I'm just confused now about what I'm supposed to do. What tool should I actually be using to edit the hex in the BIOS?

 

EDIT: I figured out what to do, but after flashing it twice, it's still not working.

Yes, I changed the theme size as well. I believe it might be a BIOS limitation, because the BIOS screen and POST screen have the same borders, even before loading anything of any OS. Interesting to note, when I shut OS X down, there are a few lines on a black screen, but this time they fit the whole screen.
