Boot Screen

[InkMaster]

Hi all; currently I don't really have any boot screen on my hackintosh - just the white text over black bg loading all scripts/files and whatnot --- is there any way that I could get the "regular" apple boot screen? The one w/ the apple and the gear - and preferably so it works @ 16x10 resolution so it doesn't look all stretched out... any way to do this?

 

thanks.

insert in apple.comBoot.plist

 

<key>Kernel</key>

<string>mach_kernel</string>

<key>Kernel Flags</key>

<string></string>

<key>Boot Graphics</key>

<string>Yes</string>

 

 

 

Hint: use Prefedit or PrefSetter.

thanks, that made it work - but is there any way to make it the "native" resolution? -- that being 1280x800 - just so it doesnt look stretched out

Tack this onto the end of the same file (com.apple.boot.plist):

 

<key>Graphics Mode</key>

<string>1280x800x32</string>

 

That's assuming, of course, that you can support 32-bit color. If not, change the "x32" to "x24", "x16", or whatever color bit depth your graphics card can handle.

and ummm.. once it stop's booting (i.e. restarts a second after it loads the boot screen; which is btw still at it's old resolution) would anyone have any suggestions for how to fix such a problem? preferably w/o reinstalling everything (again)

 

PS: Would a GMA 900 even support 1280x800x32 at boot?

 

***update***

 

I got it to boot up again, but still - a 1280x800 boot screen would most definitely be nice

so; no more solutions I take it?

Basiclly I found samething as you find

there is limit on the max resolution we can get on boot screen

 

my resolution is 1680x1050

and no better what I set in the boot.plist

 

it looks like ugly streched 1024x768

 

I suggest you to go some search in the forum, I remember some post saying maximun resolution is 1440x960 but I can't find now

 

let me know if you find out anything

ok, I find the reason

read the following post

 

 

http://forum.insanelymac.com/index.php?sho...=Graphics+Mode#

 

 

seems its the reason of hack kernel doesn't support higher resolution

 

 

we left with no help

The boot graphics is completely independent of your OS X resolution, it is an image of a set size that can't be adjusted, there would just be too much margin for error to have fancy resolution changing graphics during early booting stage. You can't set it higher or lower.

I can't agree, yes you can change the boot resolution in the real mac and in my G5 with 24' screen, it is definately 1920x1200, its not like in windows.

 

However, is seems the hack kernel broke this function so no matter how you set in boot.pl, it won't work

[Neonkoala]

Well I'm just telling you that due to the limitations of BIOS and the Darwin bootloader it can't be changed as EFI is responsible for controlling it on a real Mac thus it isn't possible for OS X to grab a true resolution.

[offall]

I am still partly disagree. though I agree that its kernel problem but I am not sure whether it is due to the no true resolution availble at booting

actually when you force boot with com.boot. its already told kernel to use true resolution but kernel still not responding.

 

Another evidence show its not because we don't have EFI.

My G5 is bios based and no EFI and boot screen is in native resolution

OK but the G5 is based on a totally different architecture and I forget what its called now but boots using a completely unique process. The Intel system upon which OSx86 is based is 100% reliant on EFI as all Intel Macs have it.

 

EDIT: Found it, it uses Open Firmware the old PPC machines.

Ok now I am convinced about EFI part, still can't explain why you sepcify the resultuon in com.boot, you can force to change resolution back in 10.4.4 (I started from 10.4.3 and only from 10.4.6 this function is suddently stopped working.

 

 

I think that means the the early version of carcked kernel are able to do so

but the new kernel makers are lazy and they didn't enable this function,

[Neonkoala]

It is probably a feature back from the 10.4.1 days, I can't think of any success stories using that boot option of recent times so I would say look into that. I doubt it is even included as a function in the newer kernels as they were'nt designed with ADP2 systems in mind. PErhaps you can port it though.

This explanation sounds reasonable, the early version of 10.4 (I am sure 10.4.3 can do it without problem) designed this feature to be compatible with ADP.

But now since all the ADPs are recycled by apple (is it true?) they dont care it and canceled this function.

 

But when exactly did they canceled the function? 10.4.4 or 10.4.6?

 

I guess the major part of this is in the kernel only, so those (e.g Paulicat) who make kernel should able to re-enable it easily, no need to "port" it

(not easy for me though, I haven't ever seen the source code for their kernels anywhere)

Are you guys talking about the spinning wheel gray screen? If so, I can confirm that it is and always has been perfectly able to work at different resolutions, including my native 1280x1024.

 

And that's not a BIOS screen nor has to do anything with BIOS or EFI, its actually OS X.

Hi, Proteo

Thanks for reply, yes, we are talking about the startup grey screen with spinning thing.

So the resolution is ok for you?

 

Could you let us know what version of OSX and what version of kernel you are using.

 

And your video card and video drivers as well

 

 

Thanks
