Here is how to setup
Gentoo on my
brand new asus.
Summary :
- Resize partitions with gparted.
- Setup minimal gentoo
- Update Windows 7 boot loader
Partitioning :- Burn last GParted live iso (current is 0.5.2-9).
- Enter BIOS (sup key)
- Switch boot devices
- Launch GParted
- Remove 30 GB from D: (/dev/sda5)
- Add / partition : 25 GB (/dev/sda6)
- Add /home partition : 5 GB (/dev/sda7)
I don't think I need a swap partition.
To install Gentoo, I followed both
x64 (last updated in 2008) and
x86 (updated in 2010) guides.
- Boot : gentoo with fr keymap.
- Set root pasword : passwd ...
- Load wifi : modprobe ath9k
- ln -s /etc/init.d/net.lo /etc/init.d/net.wlan0
- Edit /etc/conf.d/net and /etc/wpa_supplicant/wpa_supplicant.conf
Copy them from another box through a usb key or edit them from scratch with nano.
/etc/conf.d/net :
modules=( "wpa_supplicant" "!iwconfig" )
wpa_supplicant_wlan0="-Dwext"
/etc/wpa_supplicant/wpa_supplicant.conf :
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1
network={
ssid="freebox_essid"
key_mgmt=WPA-PSK
psk="secret"
priority=20
}- Start network : /etc/init.d/net.wlan0 start
- Mount partitions :
mount /dev/sda6 /mnt/gentoo
mkdir /mnt/gentoo/home
mount /dev/sda7 /mnt/gentoo/home
Stage3 :cd /mnt/gentoo

- Save boot sector (to some usb key):
dd if=/dev/sda6 of=boot.grub bs=512 count=1
Reboot :exit
umount /mnt/gentoo/dev /mnt/gentoo/proc /mnt/gentoo/home /mnt/gentoo
reboot
Update boot loader :- Steps based on this post
- Copy boot.grub to C:\
- Open a cmd as administrator :
C:\>bcdedit /export bcdedit-export-100513
L'opération a réussi.
C:\>bcdedit /create /d Gentoo /application BOOTSECTOR

Notes :
- grub menu is not visible ?!
- A lot of packages need to be emerged, still.
Some hardware info is available in
next post.
