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. Link to comment Share on other sites More sharing options...

Same here, but i wish EFI+vanilla+poweroptions (battery)+speedstep (if possible) all togather Empra Link to comment 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! Link to comment Share on other sites More sharing options...
