coolbgdog Posted August 20, 2005 Share Posted August 20, 2005 I have a intel 82845g integrated graphics card and when Im loading up osx I tried to do the command "Graphics Mode"="1024x768x32@85" at the screen and when I press enter It justs restarts the computer. In the upper left screen it says vesa 3.0. I dont know why its doing that.

RevoX Posted August 20, 2005 Share Posted August 20, 2005 your intel graphics card is not supported. it only gives you a 800x600 in 4 bit colors. I suggest finding another graphics card or using os X x86 in vmware.

coolbgdog Posted August 20, 2005 Author Share Posted August 20, 2005 It works using -x boot and I have a radeon 9250 pci card which works though.

juneyong Posted August 23, 2005 Share Posted August 23, 2005 i have a GeforceFx5200 on my computer. OS X runs in 1024x768. i go upto 1280x1024 @60hz by passing "Graphics Mode"="1280x1024x32@60" during boot process,but its not run. how could OS X runs in 1280x1024?

rohde Posted August 24, 2005 Share Posted August 24, 2005 Can any of you get a refresh rate higher than 60Hz? I can't and I'm almost passing out here - the 60Hz is killing me slowly but surely: at frequent intervals I need to bang my head against the desk to set my eyes back into place. No, seriously 60Hz is inhumane. Link to comment https://www.insanelymac.com/forum/topic/633-vesa-30-card-cant-boot-into-graphics-mode/#findComment-6494 Share on other sites More sharing options...

cabrito Posted February 8, 2006 Share Posted February 8, 2006 i have also the 82845G. after installation it just started in grey colorscale. i couldnt even recognize the icons on the screen. i tried the "GraphicsMode"=... stuff but it didnt work. i went into BIOS and increased the memory buffer of the graphics card from 1MB to 8MB and it worked!! suddenly on the boot prompt you can read VESA v3.0 7MB and it boots into 32bit color... Of course no graphics acceleration but i've gotten further... good luck!

kikos Posted February 10, 2006 Share Posted February 10, 2006 Has anyone tried changing Darwin's default resolution in graphics.c to something higher than 1024x768? If you don't know what I'm talking about, see here for reference: http://forum.osx86project.org/lofiversion/...hp/t2839-0.html I have an Nvidia GeForce 6600 that Darwin says supports Vesa 3. The information that Darwin is getting from my video card is incorrect as the max resolution according to Darwin is 1024x768x32. I looked at how graphics.c works and I think i know why when some people type in "Graphics Mode"="1280x1024x32" OS X still boots in 1024x768. In short, graphics.c is checking to see if the user typed in a resolution darwin thinks is supported by your card, and if there's a match Darwin (OS X?) will boot in that resolution. Otherwise darwin boots using the highest available rez or uses the default resolution of 1024x768. One of the last functions in graphics.c is setVideoMode. I think this part of the code takes some variables based on what Darwin thinks about your video card and sets the resolution based on the variable. I'm interested in the part of setVideoMode, where the default setting is established: params[0] = 1024 params[1] = 768 params[2]=32 My plan is to change params[0] to 1280 and params[1] to 1024. I'm curious to see if Darwin will accept this and pass this graphics mode to the OS X GUI since OS X is not loading a kext and is presumably relying on vesa info from Darwin. Has anyone already tried changing the graphics resolution through graphics.c and compiling a new boot binary? The problem I'm having is that I can't compile the boot source. I have xcode 2.2.1, boot-122.tar from the 10.4.3 source directory, and I'm running OS X 10.4.3. I have gcc set to version 3.3. , but when I run make, the compiler can't find the cc1 executable. Any ideas? I think the error is something like "cannot exec cc1" Link to comment https://www.insanelymac.com/forum/topic/633-vesa-30-card-cant-boot-into-graphics-mode/#findComment-54883 Share on other sites More sharing options...
kikos Posted February 11, 2006 Share Posted February 11, 2006 Short version: Overwriting the modified boot file might work for people stuck in 1024x768. I wish I could still test this myself, but now that darwin recognizes my card better, I can't. Alternatively people stuck in 1024x768 might try a native install from the 10.4.3 8f1111a Jas Patch 4.2b Long version: After modifying graphics.c , I compiled the new boot file and then ran the startupfile tool. The system started to boot up in 1280x1024 mode, but crashed during boot. Recompiling graphics.c to the default didn't work, so I had to reinstall OS X in order to get it booting again. I blame the startupfiletool for this problem because, later on a VMWare OS X, I simply overwrote the boot file with my new boot file and it booted fine. After re-installing OS X natively, I was going to try to overwrite the boot file manually rather than using startupfiletool. But now, ?video tells me that my video card can achieve several resolutions higher than 1024x768. I'm not sure why this is, but there is a difference between my installation methods the first time and the second time. The first time, I originally installed to my USB drive in VMWare and used disk utility to copy OS X to my blank IDE drive. Max resolution here was 1024x768. But the second time, I booted from my PC using the JaS patched OS X installation DVD. Max resolution is now 1280x1024. But now even my unchanged USB drive will boot into 1280x1024 if I boot from it. Doesn't make much sense to me. Link to comment https://www.insanelymac.com/forum/topic/633-vesa-30-card-cant-boot-into-graphics-mode/#findComment-55368 Share on other sites More sharing options...
