surfstu Posted June 29, 2010 Share Posted June 29, 2010 ok, I installed on a lenovo g560 after installing win 7, then win 7 would not boot but osx SL was great. Then after i fixed win 7 install, my bios crashed? the laptop has gone back to shop, is it possible for [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] or any other part of install to crash a bios so much that one cannot enter bios setup? Can the efi partition be responsible for this? surley not? surley computers are more robust than this? stuart Link to comment https://www.insanelymac.com/forum/topic/223133-can-osx-completley-break-a-pc/ Share on other sites More sharing options...
surfstu Posted June 29, 2010 Author Share Posted June 29, 2010 Anyone with more knowledge than me care to comment on whether it was possible for me to wreck a computer to the extent that it would not enter bios setup or the F12 (choose disk to boot from) menu? It just stalls during POST, I thought this was only possible to do if updating bios? stuart Link to comment https://www.insanelymac.com/forum/topic/223133-can-osx-completley-break-a-pc/#findComment-1500736 Share on other sites More sharing options...
surfstu Posted June 29, 2010 Author Share Posted June 29, 2010 no-one daring to answer this question? It is quite relevant because if OSX can break a PC beyond user repair, fewer people would be doing this..............

danielkza Posted June 29, 2010 Share Posted June 29, 2010 As far as I know the only way for you to screw up your PC is using wrong voltages while trying to get SpeedStep to work on your DSDT. You'd have to up them very high, what unfortunately can be caused by a single typo. All the other modifications will, at most, cause OSX to malfunction, but never damage your hardware. And you can't screw up the BIOS by messing up with partitions. The disks aren't even spinning when the BIOS starts, and may be not present at all. The BIOS doesn't know or care about partitions: all it does is set up whatever it's supposed to, read the first sectors of the chosen boot drive, and give up control to the boot code.

surfstu Posted June 30, 2010 Author Share Posted June 30, 2010 thankyou, this is exactly what i thought, so it seems that the h20 bios used by lenovo is a tad unstable and has caused my laptop to be useless until a new bios is loaded, which can't be done by me because i have no idea what bios to put on it, the manufacturers website give an exe bios that can be loaded via windows.....

surfstu Posted July 1, 2010 Author Share Posted July 1, 2010 How did you find out that it can ruin your bios? i found out the hard way, with a £700 laptop bought last week, only to find there is little support from lenovo for their new insyde h2o efi based bios, many new PC's are adopting this now too Link to comment https://www.insanelymac.com/forum/topic/223133-can-osx-completley-break-a-pc/#findComment-1502348 Share on other sites More sharing options...
snsr Posted July 1, 2010 Share Posted July 1, 2010 My T60p (C2D - 2613-CTO) is seemingly fubar after iATK Leopard last year. Most of the time the system won't even POST (the system is back to Windows 7.) When it does, however, everything works as normal. Haven't yet tried re-flashing the BIOS, but I'm going to after reading this.

At least you can get into windows, just use the windows flash download of bios for your pc from the manufacturers site, it just may solve your problems Link to comment https://www.insanelymac.com/forum/topic/223133-can-osx-completley-break-a-pc/#findComment-1503004 Share on other sites More sharing options...
