Install Windows 8 consumer preview at virtualbox

Installed at w8 cp at VirtualBox in Ubuntu 11.10.
The default version of VirtualBox that came with 11.10 is version 4.1.2.
No Windows 8 option, so select others, system will up, and stop at recovery option.

Google found that 4.1.8+ version should already come with w8 option, update to 4.1.8, w8 up without problem.

Build UEFI EDK2 UnixPkg 64bit under Ubuntu 11.10

Two place need to modify :

1. Link crt*.o to correct place :

root@neou11:/usr/lib# ls /usr/lib/crt* -l

lrwxrwxrwx 1 root root 32 2012-03-04 02:37 /usr/lib/crt1.o -> /usr/lib/x86_64-linux-gnu/crt1.o
lrwxrwxrwx 1 root root 32 2012-03-04 02:37 /usr/lib/crti.o -> /usr/lib/x86_64-linux-gnu/crti.o
lrwxrwxrwx 1 root root 32 2012-03-04 02:37 /usr/lib/crtn.o -> /usr/lib/x86_64-linux-gnu/crtn.o

2. Use GCC 4.6 instead of 4.4 :

neo@neou11:~/work/edk2-12898/UnixPkg$ svn diff build64.sh

Then SecMain could be built, and running.

Ubuntu 文字模式開機

sudo update-rc.d -f gdm remove

or
echo false > /etc/X11/default-display-manager

/etc/X11/default-display-manager 記錄了用哪個 display-manager
如果是 gdm, 多半是 : /usr/sbin/gdm
