root@debian:~# cat /etc/issue
Debian GNU/Linux 7 \n \l

However, the above command may not show the current Debian update point releases. Thus you may get more accurate info with the following command:

root@debian:~# cat /etc/debian_version
7.7

1. prepare usb in on some linux machine

check where is usb; probably on /dev/sdb

#umount  /dev/sdb

#cat *********.iso > /dev/sdb

2. in Bios;

bootseq: usb -> HDD

3. Then boot.

Successful!

Incomplete. Forget it.

Recent debian Kernels are SMP compatible.

You can check the SMP compatibility by “uname -a”. The output would contain word “SMP”.

1. download kernel sourece:

root@mamiko-PC:/usr/src# ls
linux-patch-3.2-rt.patch.bz2  linux-source-3.2.tar.bz2

2. unzip:

root@mamiko-PC:/usr/src# tar xjf linux-source-3.2.tar.bz2 root@mamiko-PC:/usr/src# bunzip2 linux-patch-3.2-rt.patch.bz2

root@mamiko-PC:/usr/src# ls -l

3. patch:

root@mamiko-PC:/usr/src# cd linux-source-3.2

root@mamiko-PC:/usr/src/linux-source-3.2# patch -p1 <../linux-patch-3.2-rt.patch

4. install qt4-dev-tools package

5.

Static IP address

There are various reasons why you may wish to assign static IP addresses on your network. For instance, one may gain a certain degree of predictability with unchanging addresses, or you may not have a DHCP server available.

A static address can be configured with most networking tools standard in Arch Linux, for example see netctl, systemd-networkd, dhcpcd.

The following describes how to configure a static IP address manually. You need:

• Static IP address
• Subnet mask in CIDR notation, for example /24 is the CIDR notation of 255.255.255.0 netmask.
• Broadcast address
• Gateway‘s IP address
• Name server (DNS) IP addresses. See also resolv.conf.

If you are running a private network, it is safe to use IP addresses in 192.168.*.* for your IP addresses, with a subnet mask of 255.255.255.0 and a broadcast address of 192.168.*.255. The gateway is usually 192.168.*.1 or 192.168.*.254.

iface eth0 inet static
address 192.168.1.16
netmask 255.255.255.0
gateway 192.168.1.1

Above is not for debian.

Important!

Everything is in file:  /etc/network/interfaces

Never put more than one gateway!!

This could make it.

In the starting process of recovery mode, it seems doing fsck and reporting the result.

It may be good practise to run recovery mode once in a while.

select “gnome classic” at the login.

It is set to default from then.

gksu gedit /etc/hibernate/common.conf
DownInterfaces wlan0
UpInterfaces auto

It is not allowed, and it is normal.
Workaound;
as normal user
gksu gedit
Although you would get warning messages, it works.
