EDIT: keybord Fn key setting doesn't work for me. The temporary settings is fine, but all methods had failed to save that settings...

Interesting. Can you post the output of /Applications/Utilities/Partition Inspector ?

rEFIt, by default is installed to the OSX partition not the EFI partition.

Also, keep in mind that you have two different partition tables that you are dealing with. The OSX partition might be marked as bootable on the GPT side, but not the MBR side...

you can actually try booting with grub-efi without modifying your current install (i.e. you can still boot in legacy mode normally.

Will post my "sudo fdisk -l" & "df -h" data a bit later (MBP's @ home).

Still getting to grips with the whole EFI/GPT partitioning/boot, so I don't want to break anything quite yet (all the bits & pieces are working well, so I'd like to keep it that way)

I thought rEFIt ran out of the 200MB EFI partition in a similar way that GRUB runs out of my "/boot" partition. Otherwise I see little reason for that partition to be there in the first place.

Not too sure what the stability of grub-efi is like, especially on a 64-bit environment. Once I'm a bit more informed & confident I may commit to it.

Using rEFIt has significantly improved my boot time & stability, compared to how it was in the monolithic installation before.

Was hoping rEFIt/EFI would open up more advanced booting features, like that of the "ExpressGate Pre-Boot OS"; having something like a functioning OS prior to the full OS being up. (but that's not a huge concern)

On a separate note; power management is better, but still not perfect.
If put the MBP into hibernation & bring it back up again, the synaptic touchpad is not operational. To fix this I simply put it into suspend (close the lid/screen) & bring it back again, and it seems to work OK.
2-finger scrolling works fine (horz & vert), but I now have to trigger right-click with 3 fingers instead of 2. Which is actually not such a bad thing.

Will post my "sudo fdisk -l" & "df -h" data a bit later (MBP's @ home).

fdisk can only read the MBR partition table...

nope, unless you specifically placed it in the EFI partition, it is install in /efi/refit on your OS X partition.

The EFI partition exists because the EFI spec really requires it to be there (it is also used for firmware updates)

Was hoping rEFIt/EFI would open up more advanced booting features, like that of the "ExpressGate Pre-Boot OS"; having something like a functioning OS prior to the full OS being up. (but that's not a huge concern)

rEFIt is an EFI executable. nothing is running except the Mac firmware at that point. rEFIt just gives you a nice interface to the bootselector already on the Mac (holding alt on statup will get you to the default selector). It also provides a few nice tools (also efi executables) and the partition inspector tool that I referenced above.

Thanks for the info, cd33.
Obviously I don't understand it quite as well as I thought I did.

If I can port my "/boot" & GRUB into the 200MB primary (EFI) partition, I'd be a much happier camper.
I think I read somewhere that GRUB2 has support for EFI, but at the moment it's not quite stable enough (same goes for EXT4).

Since the MBP hardware is still a [black box] to me (hwinfo & lshw can only tell you so much), regardless of how nice it is, I'm a bit hesitant to do anything that might break it. But I'll probably end up breaking it anyway (as I tend to do), so if you have any advice or references you think I should consult, I'll give it a try.

You referring to the "Partition Inspector" under Mac? Will have to switch & post again.

In the mean time, I attached a screenshot of my gparted, fdisk & other disk info I can track down (just in case). Will amend with "Partition Inspector" screencap after reboot

Pretty weird that some partition inspectors see the EFI partition & other inspectors see the OS X HFS+ (sda2 / disk0s2) set with bootable flag

If you're not too much regarding about the wireless connection, yes Jaunty works well.

I've never got the wireless speed and quality I had on Hardy with the madwifi driver.

All the data seems normal for how you are booting.

The difference in the boot flag, is the difference between the GPT and MBR partition table. in the MBR table, the OSX volume is set as bootable (that is what you want since that is where rEFIt is) and in the GPT the EFI partition is set as bootable (which is correct as well).

I still don't know how you got grub to boot from partition 6, but if it works, it works.

[freakalad]

cd33, IYO, do you reckon that grub-efi & grub2 are stable enough?
Are there any advantages in implementing it & wouls it improve my boot time & stability, or would I only be complicating things needlessly?
