====== Gentoo on MacBook Pro(MD318, 15inch, late 2011) ======

Cheers, finally I made it, the Gentoo back to work on my MacBook Pro.

I have spent several days to make the Gentoo back, because previous it works, but after one update whatever, it can't start the X.

The biggest problems I met is 
  - Hard Disk IO bug, the M4 SSD need upgrade the firmware
  - The init system has changed from OpenRC to Systemd.
  - Can't start X(startx, Xorg -configure, X -configure, aticonfig --initial) doesn't work

So you can image how difficult it is to fix all the problems, because
  - The MacBook Pro doesn't support the usb bootable device
  - I don't have DVD ROM, because I have replaced it with one Hard Disk.
  - Sometimes the keyboard doesn't work for X and kernel problems.
  - I don't aware the difference between OpenRC and Systemd

===== Upgrade the M4 SSD firmware without DVD ROM =====
  - Download the firmware from the official website
  - Get the BOOT2880.IMG from the iso file
  - Download the riEFI  file
  - Mount the EFI and get the SYSLINUX
  - cp -a SYSLINUX /boot/
  - cp BOOT2880.IMG /boot/SYSLINUX
  - Boot to the grub and press "c" to do the manual boot
<code Bash>

kernel /boot/SYSLINUX/ubnkern
initrd /boot/SYSLINUX/BOOT2880.IMG
boot
