Hi.

My laptop has a widescreen display (1280 x 768)

Under Mac OS X, that resolution works fine,

however, when booting, it seems that

the apple is stretched, it looks like 800 x 600.

Is there a way to fix that resolution so the apple

is not streched, yes, I know, what is the importance

of that? The importance is that we are trying (or at least I)

to have the system the most similar to a real Mac.

 

Help is appreciated.

Thanks

Good question. I think using a command at the Darwin prompt could fix this. It would look like this:

 

"Graphics Mode"="1280x768x32" (you must use the quotation marks)

 

Try that, and see if it works. If it does, you can place it in the com.apple.Boot.plist, and it will always launch in that resolution.

 

=================

 

Edit:

 

Ok, I just tried this, and it appears to fix the problem. :)

 

You can follow the directions here on how to edit the com.apple.Boot.plist file so that command is issued every time: http://wiki.osx86project.org/wiki/index.ph...he_boot_options

 

To automatically use a certain graphics mode:

 

<key>Graphics Mode</key>
<string>1280x1024x32@85</string>

 

You won't need to use the @85 (refresh rate) since it will be determined when OS X starts up.

 

Hope this has helped.

That command doesn't work for that boot 'stage'.

 

If I'm not mistaken it's an feature that got lost when the kernel got hacked, I assume it's not BIOS/EFI related as it does boot up with the correct resolution on a Intel mac with EFI as on the old PPC procs with a BIOS.

 

I'm just a n00b though :whistle:

Do I really have to prove myself to you? Do you honestly think I'm going to take photos to show you?

 

No offence, but if you don't believe what I'm saying now, why should I bother to show you. I'm telling you - this method works for me. Hold down F8 when booting your Mac OSx86 partition, enter this command, including the quote marks & capitalisation:

 

"Graphics Mode"="1280x768x32"

 

Edit:

 

And for the record, I'm on 10.4.9 + 8.9.1 kernel.

It works for me as well so it does work... press F8 to enter command mode before booting and include everything he typed including the ""

 

Great! :thumbsup_anim:

 

Sorry if I made an offence...

Well, I just wanted to see how it worked and if I was doing something wrong...

 

Well, thanks, trying again just right now...

 

Sorry if I came on a bit strong - I shouldn't have. Anyway, did it work?

Hmm, thought you were mistaken :tomato:

 

but it never used with the 8.8.1 kernel (SSE2) Think I'll do a reboot and try it with the new one :thumbsup_anim:

 

Doesn't work for me, or maybe it does but..

 

It doesn't change res wise, even when I put in 800x600, 1024x768 or 1248x1024.. And for you guys, it prolly only stops the stretching out, while at my lil bro's macbook the apple looks perfect on high res.

No, it doesn't look stretched. The apple also looks clear and crisp for me too.

Could you tell me what kind of res you use for the booting? (and the size of the apple? :) )

 

Or do you have any idea how to check the res at that booting stage? XD

 

The resolution when booting the Mac partition is now 1600x1200. I can tell because when I go into verbose mode the size of the text is much smaller than what it used to be. Also, the Apple logo becomes smaller too.
