mac-fish Posted July 25, 2008 Share Posted July 25, 2008 hi, just got leo4all v3 working on the d600 i have here... the problem is, i can´t boot it up... always get that error: Hey, we are going backwards! -> restart timing. Hey, we are going backwards! -> restart timing. Calibation failed with 2 attempts so, i´ve searched and googled around for some time, and found out what flags could fix this... for example platform=X86 or cpus=1, also found out you have to disabled ACPI to fix this... but nothing of those tips helped me to fix this annoying issue... i CAN boot with dvd by typing: rd=disk0s2 -x -v BUT it is very annoying, i can´t install any drivers using that way, and it´s only loading safeboot kexts... tried playing around with the kernels at install, and also with bios, where i found out, that disabling USB Emulation fixes this error but then it immediatelly reboots when trying to boot. BIOS version is A16... also strange is: i couldn´t find this version of the BIOS on the dell site o.O i´m using boot_v5 to start darwin over GRUB ( ubuntu 8.04, standard GRUB 1.5 ) Link to comment https://www.insanelymac.com/forum/topic/117603-problems-with-efi/ Share on other sites More sharing options...

LVNeptune Posted July 26, 2008 Share Posted July 26, 2008 That happened to me...Few different things I believe caused it. 1) Check BIOS time, make sure it is right, OSX keeps changing my BIOS time for whatever reason. 2) Remove any peripherals you don't need while booting the system, (USB drives, etc.) see if this helps...

Gujal Posted July 27, 2008 Share Posted July 27, 2008 Also try installing Chameleon Bootloader. It may help fix the issue. http://chameleon.osx86.hu Link to comment https://www.insanelymac.com/forum/topic/117603-problems-with-efi/#findComment-835455 Share on other sites More sharing options...
