GRUB2 -> Chameleon

28 September 2013 - 11:34 PM

situation: disk containing osx86 and linux. boot loader was Chameleon, replaced by GRUB2.

 

boot linux and extract Chameleon's i386.zip into /boot/chameleon

then edit file /etc/grub.d/40_custom in order to add this lines:

menuentry "OSX86 Chameleon Boot Loader" {
chainloader /boot/chameleon/i386/boot0
}

after save, run update-grub2

done!

 

EDIT: simplification... chainloader pointing to chameleon's boot0 do the trick

________

useful chameleon recovery commands

(cd /boot/chameleon/i386)

dd   if=boot0   of=/dev/disk/by-id/TheDiskThatYouAreUsing   bs=440   count=1

dd   if=boot1h   of=/dev/disk/by-id/ThePartitionWithOsx86OfTheDiscThatYouAreUsing   bs=512   count=1

cp   boot   /the/root/of/your/osx86/mount/point/

 

dont copy-paste, just take as reference!

please use dd (destroyer of disks) with precaution, you can kill a little cat if used wrong!

Kernel memory footprint

06 February 2013 - 09:15 AM

hi all!

recently, i have been testing sinetek's 64 bit legacy kernel. dealing with system logs, amd_insn_patcher, dyld, libSystem.B, update_dyld_shared_cache, and all that...
i finally got sinetek's kernel running for a while, until a system crash happens. it happened when i noticed a very high kernel memory use (650MB)
so i decided to test nawcom 10.6.8v2 kernel, and after some hours, 930MB (!) used only for kernel.
now im back to avn legacy kernel (the most stable i found), and im cheching also memory footprint. as above, kernel memory footprint increases slowly. actually when im typing this, it has reached 500MB.
and its constantly growing!!

i would like to ask those unmodified mach_kernel users, and the other legacy_kernel users, what is their memory footprint, in order to compare.

im not sure if there is something wrong.

best regards
