ZiGOMATiK Posted April 15, 2011 Share Posted April 15, 2011 Hello, I try to boot on the DVD of Mac OSX (iDeneb 1.5.1 or iATKOS S3 Snow Leopard) but I see the official bootscreen of Mac OSX during 1 or 2 seconds and then my PC reboot. My PC is a HP EliteBook 8540p (Intel Core i5, 4 Gb RAM, ...). I already try to boot with cpus=1 flag or -x -v -s .... But there is no effect, I can't boot on Mac OSX. Have you any idea ? Thank you.

Insomni4k. see your multipler ratio in your bios then put this flag busratio=xx where xx is the number signed by your multiplier (ex. for my i7 I have to write busratio=20) Link to comment https://www.insanelymac.com/forum/topic/254907-reboot-on-bootscreen/#findComment-1670735 Share on other sites More sharing options...

ZiGOMATiK Posted April 15, 2011 Author Share Posted April 15, 2011 Thank you a lot, it works ! But I have another question. I installed OSX on a USB Key and I use the new version of Chameleon to boot on my key. This one (and sorry for the very, very, crappy pic ) How can I edit the boot flags to add busratio=18 (for my case) ? It is possible ?
