Antonio92 Posted February 7, 2010 Share Posted February 7, 2010 I have had Leopard OSx86 installed on my Toshiba Satellite A300-203 laptop for months with no problem, but suddenly it refused to boot. Since like one month ago, I get kernel panic each time I try to boot it, just by the time the Apple logo shows up. I tried to install it back with the DVD but when Apple logo shows up I get the same (kernel panic). I have no idea at all about what can cause this problem, I didn't do anything special (maybe updating bios can cause this? I updated it other times with success and Leopard booted normal). This is what I get when I boot in verbose mode: As you can see, there is no error, it seems to load the kernel and then there is the panic. I have to manually shutdown the computer after getting what you can see in this picture. What can I do?

jeryia Posted February 10, 2010 Share Posted February 10, 2010 did you try another distro? Link to comment https://www.insanelymac.com/forum/topic/210153-leopard-osx86-used-to-boot-doesnt-do-anymore-though/#findComment-1407466 Share on other sites More sharing options...
nerdocrat Posted February 10, 2010 Share Posted February 10, 2010 What kernel are you using? Chipset? Link to comment https://www.insanelymac.com/forum/topic/210153-leopard-osx86-used-to-boot-doesnt-do-anymore-though/#findComment-1407595 Share on other sites More sharing options...
Antonio92 Posted February 11, 2010 Author Share Posted February 11, 2010 I tried some different Leopard distros (iDeneb, iPC, XxX...), a tiger distro and a snow leopard distro (Universal), all getting kernel panic at boot. My chipset is Intel ICH10. It used to run perfectly until I updated the bios. The picture I posted on the first post of this thread was taken when I booted vanilla kernel. This is what I get when I boot voodoo kernel in verbose mode: What can it be? I guess some ACPI / APIC issue, but I have no idea about it Link to comment https://www.insanelymac.com/forum/topic/210153-leopard-osx86-used-to-boot-doesnt-do-anymore-though/#findComment-1408001 Share on other sites More sharing options...

phoenix_iii Posted February 16, 2010 Share Posted February 16, 2010 Any hints????? Put old bios back on... or look to see what got 'turned on' (or off!) in the bios that's upsetting osx.

Thanks in advance Antonio Greetings, I know for a fact that most computers using a vanilla kernel can be updated straight from Apple until 10.5.5. After that your BIOS needs the DSDT patch or else 10.5.6 cannot run at all. I also know that when an update from Apple fails the only way to get it working again is to COMPLETELY erase the partition for Mac and do a fresh install. In simpler words: You may have updated to 10.5.6 without patching your bios with the DSDT patch which means you'll need a fresh install.

RoyV Posted February 17, 2010 Share Posted February 17, 2010 I think what might be the cause are your bios setting? Probable causes can be USB settings, display settings CPU settings I had the same problem when I changed some CPU settings (hyperthreading enabled) and then it froze. I changed back and it booted normally again.. I'm a complete noob at this so I hope this helps :-) Link to comment https://www.insanelymac.com/forum/topic/210153-leopard-osx86-used-to-boot-doesnt-do-anymore-though/#findComment-1411912 Share on other sites More sharing options...
Antonio92 Posted February 17, 2010 Author Share Posted February 17, 2010 But everything in BIOS seem to be as normal... I also tried to restore factory defaults and change some values with no success. I can't put old bios back on because there is no way to do a downgrade (I was looking for it with no luck) @-tanner-, I can't do a fresh install as the OSx86 DVD doesn't boot! I get the same problem when trying to boot the osx86 dvd. I can't boot voodoo kernel aswell, I said. I have no clue about what to do Link to comment https://www.insanelymac.com/forum/topic/210153-leopard-osx86-used-to-boot-doesnt-do-anymore-though/#findComment-1412010 Share on other sites More sharing options...
Antonio92 Posted April 14, 2010 Author Share Posted April 14, 2010 Any hints? I still can't boot it I can't do a fresh install as I get the same error when I try to boot any OSx86 DVD Link to comment https://www.insanelymac.com/forum/topic/210153-leopard-osx86-used-to-boot-doesnt-do-anymore-though/#findComment-1448622 Share on other sites More sharing options...
oldtopman Posted April 21, 2010 Share Posted April 21, 2010 Bummer. On my old a45-s120 there were a whole bunch of processor options. Otherwise, add this to the h(incompatibility)cl Link to comment https://www.insanelymac.com/forum/topic/210153-leopard-osx86-used-to-boot-doesnt-do-anymore-though/#findComment-1452580 Share on other sites More sharing options...
Antonio92 Posted April 25, 2010 Author Share Posted April 25, 2010 I managed to boot it by typing the following flags at boot: idlehalt=0 cpus=1 but now USB ports are not working except for the USB mouse... any hints?
