Detosx Posted December 27, 2007 Share Posted December 27, 2007 I don't think this can physically work, that I would instead need two hard drives, which isn't practical with a laptop. I would love to use the vanilla kernel on GUID (though iATKOS doesn't directly support that option) - with Speedstep! That way I would have peak performance and tweak-able battery life. In that I can't have that, I wondered if there was some way to have an EFI+MBR partition with vanilla kernel working alongside a partition with a modified kernel with Speedstep. That way I can save battery on the road and boot into the performance partition when I'm on the mains at home.

Same here, but i wish EFI+vanilla+poweroptions (battery)+speedstep (if possible) all togather Empra Link to comment https://www.insanelymac.com/forum/topic/78360-dual-iatkos-partitions-on-a-laptop-one-for-performance-the-other-for-battery-life/#findComment-554887 Share on other sites More sharing options...
justvisiting Posted December 28, 2007 Share Posted December 28, 2007 I don't know how at the moment, but it is much easier to have one installation, two kernels (ex. vanilla_perf, vanilla_battery) and set your boot loader to present you with the option to select one.

Detosx Posted December 28, 2007 Author Share Posted December 28, 2007 I originally had three partitions - Vista, Tiger and Leopard. I replaced the third with iATKOS using the Darwin X86 bootloader and Speedstep. Everything went fine. I then formatted the Tiger partition and installed iATKOS using the Darwin EFI. No surprise, it didn't work - I was left with just a blinking cursor at boot. In gparted I could see the partition was set to boot. I then tried making the x86 partition active but still was left with the blinking cursor and no F8 option. I am now installing X86 option to the former Tiger partition, which should give me the ability to boot into both partitions. Edit - it didn't work, I am left with a blinking cursor! Clearly I borked the partition table in some way, though the partitions are in tact. I might have to install to a USB drive, rescue my data and do a clean install. No harm in that! Does anyone know if dual-core chips (as opposed to Core 2 Duo) play nice with GUID and EFI? Fun and games. Re two partitions, one for battery and one for performance - if anyone has managed an artful compromise, I would be glad to read!
