Create One Touch open close button for CD DVD drive Tray

Create One Touch open close button for CD DVD drive Tray

I have published a post about opening and closing cd/dvd drive tray with (mouse left click) one click button several months ago. I named that post as open close CD tray by mouse click on ubuntu . One of my readers ask me that s/he can not understand the method. S/he requested me to explain the process detail.

So I am writing the post. I have two optical drive attached on my machine. I will create two buttons to open or close my first CD Drive. I will create buttons on top or side menu on Ubuntu Linux Desktop system.


Open Close One Click Button for CD Drive:

• a. Right click on panel body. A drop-down or pop-up menu will open.
• b. Select Add to Panel from the list. A Add to Panel dialogue window will open.

"Add to Panel" dropdown menu.

Add launcher panel dialogue window 

• c. Click on "Custom Application Launcher to create a new launcher.
• d. Now type description and command one by one as shown on the picture below.
• I wrote Open CD Rom on Name field.
• At Command text box I wrote "eject /dev/sr0" to Eject my first optical drive that is CD Drive.
• At Comment text field I wrote Open CD Tray. Remember you can write anything on Name and Comment box. But must write perfect command on Command field.

• e. Now click on "Close" button. You will find a new launcher on panel. Click on this button. You primary drive tray will open instantly.

Now you want to close the CD Rom Tray? Here is the method. Full process is same.

• Right click on Panel.
• Select Add to Panel.
• Select "Custom Application Launcher to create a new launcher.
• Write anything on Name and Comment Field.
• But type a little different on Command field. Closing command is quite different from Opening Command.
• Write "eject -t /dev/sr0" Dont make mistake to give space on both side (front and end) of -t syntax there.

I wrote sr0 to specify my first drive. I will write sr1 for my second drive. If you have more optical drive connected on casing then mention them as sr2, sr3, sr4.... . Here is the screen-shot of those another launchers for other drive.

Criar um CD de instalação do Windows XP

Criar um CD de instalação do Windows XP

Bom dia galera.

A dica de hoje dever� ajudar aqueles, que assim como eu, precisam instalar o Windows XP em um netbook, como o Acer Aspire One, que foi o que eu precisei fazer alguns dias atr�s.

Para quem n�o sabe, esses netbooks n�o contam com drive de CD, ou seja, a op��o que nos resta � utilizar um pendrive para realizer a instala��o do sistema operacional, mas a� come�a o problema. Como instalar o Windows XP sem o CD.

Quebra aqui

Para fazer isso, � preciso criar o CD de instala��o, e para isso, basta usar uma ferramenta bastante simples, chamada WinSetupFromUSB.

A execu��o deste tutorial exige que voc� tenha em m�os um pendrive (�bvio, n�? rs) de pelo menos 2 GB, um cd de instala��o do Windows XP e do programa citado acima (WinSetupFromUSB).

Prepara��o do pendrive

Para baixar o WinSetupFromUSB, acesse http://www.datafilehost.com/download-109e97af.html

Detalhe important�ssimo.

Fa�a backup dos dados do seu pendrive, pois eles ser�o apagados, e n�o haver� como voltar atr�s ap�s a execu��o dos passos a seguir.

N�o me responsabilizo por perdas causadas pela utiliza��o deste tutorial.

Assim que fizer o download do instalador do WinSetupFromUSB, instale-o. No fim da instala��o, o programa ser� executado.

Insira o CD do Windows XP no drive de CD e o pendrive na USB.

Agora, no WinSetupFromUSB, siga os passos abaixo:

• Para preencher o campo �Windows 2000/XP/2003 Source�, clique na bot�o Browse e localize a letra da unidade na qual o cd foi carregado (no meu caso, D:)
• No campo �USB Disk Selection�, selecione o seu pendrive. Se ele n�o estiver aparecendo, clique no bot�o Refresh
• Em �Force Target disk type�, selecione a op��o Fixed
• Clique no bot�o GO e espere a prepara��o do pendrive (comigo levou aproximadamente 30 minutos, ent�o se quiser, v� tomar um caf� rs)
• Assim que a c�pia terminar, feche o WinSetupFromUSB.

Isso � tudo para ter um pendrive preparado para instala��o do Windows XP sem um drive de CD.

Instala��o do Windows a partir do pendrive

Reinicie o computador e cofigure, atrav�s do setup do computador, a inicializa��o pela porta USB (isso varia de computador para computador, portanto, vou deixar por sua conta).

Reinicie o computador, j� com o pendrive conectado na USB e aguarde.

O GRUB dever� ser iniciado, apresentando uma lista com 2 op��es para sele��o.

Como estamos no in�cio da instala��o, selecione a primeira op��o, e a instala��o come�ar�. A instala��o do Windows XP ser� iniciada aqui como de costume. Se voc� n�o souber como prosseguir, aconselho uma busca no Google, pois este tutorial n�o tem o objetivo de descrever a instala��o em si.

Uma vez que a instala��o esteja completa, o computador ser� reiniciado. Assim que isso acontecer, na mesma lista de op��es exibida pelo GRUB, selecione a segunda op��o, para que o Windows seja iniciado a partir do HD e a instala��o seja conclu�da.

Quando a instala��o estiver conclu�da, reinicie novamente o computador e remova o pendrive da USB.

Isso � tudo que voc� precisa para ter o Windows XP instalado e funcionando no seu netbook.

Boa sorte, e se tiver qualquer d�vida ou sugest�o, me avise pelos coment�rios.

Por hoje � s�.

Abra�o

Creating a Chroot from an Ubuntu Live CD USB

Creating a Chroot from an Ubuntu Live CD USB

Chroot is an operation that changes the apparent root directory for the current running process and its children. It has got many uses but most importantly, it can be used to repair a broken, non-bootable install from a Live environment. May the problem be with the boot-loader, non-configured packages etc, Chroot would at least give you an environment from where you can try to repair the broken install.

There are several other advanced uses of Chroot like testing unstable applications, creating an environment with dependency control etc. We are just discussing the simple ones here.

Creating a Chroot

If you've got a non-bootable PC and want to attempt to repair it, boot an Ubuntu Live CD/USB on that PC. Go to a Terminal and find out your '/' partition by running this command:

sudo fdisk -l

You need to figure the partition notation for your '/' drive which looks like 'sda1', 'sda2' etc. You can also start GParted from System > Administration menu or by searching the Dash in Unity, and try to find your partition there.

For creating the Chroot, you need to run these commands one-by-one:

sudo mkdir /mnt/temp
sudo mount /dev/sdXY /mnt/temp
for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt/temp$i; done
sudo cp /etc/resolv.conf /mnt/temp/etc/resolv.conf
sudo chroot /mnt/temp

Where 'sdXY' is your '/' partition.

The 4th command is meant to connect your Chroot environment to the internet but it would obviously only be successful if you've got internet access in the Live environment.
