After Microsoft’s Windows & Apple’s Mac, the ever growing community in todays OS market is linux. It is based on UNIX, the oldest stable and significant ‘operating system’. Actually Linux means Linux Is Not UniX, developed by Linus Torvelous and others.

Enough of these history lessons, today linux is a very common name among netizens. Being a growing community as I said before, it is in a state of constant development. Though today’s linux ‘distros’ (actually distributions) are efficient enough for normal users, many people has a common misunderstanding regarding linux in thinking it a geeky OS. But in reality it’s not after all a geeky thing. Of course, when you are thinking better customization in linux, you must have to use the terminal but for normal uses, it does not need to have a computer degree to run linux. Now it is as easy as running Windows or Mac.

Let’s stop myth-busting and now we will getting to the point. I have to mention that though well-developed, linux has some advance options that need to be tweaked to get through. I will discuss those in this thread.

1. Configuring a PPPOE or PPPOA connection in Ubuntu Feisty Fawn

There is no direct graphical application to connect to a PPPOE or PPPOA internet connection using GNOME in Ubuntu. So user have to open the terminal and enter “sudo -s” (without quotes) in there. It will ask the root password, enter it. Then type “pppoeconf”, a new window will appear as pictured below..

Then press enter selecting Yes; it will scan for ethernet devices and then prompt you to load the default profile for your ADSL modem. You will have to select these settings by pressing yes and ok when necessery. You will then have to enter your username and password for internet connection. Press enter to save and select whether you want the connection to be started at boot time. Now when the wizard completes, you are ready to go.

If you have selected to manually start a net connection, then you have to start ‘terminal’
and enter your “pon dsl-provider” following ’sudo -s’. The connection will be started.

The most common linux problems on your hp laptops can be solved by calling the troubleshooting team. Refer to your laptop guide for problems or order one if you don’t have one. The online guide will walk you through the installing laptop accessories section with ease. Check the sony laptop history for any changes in the computer before buying a used laptop scrap laptops or refurbished laptops. Refurbished dell laptops might be better than the original. When buying a refurbished digital camera, read the digital camera reviews first.

Change pio transfer mode to UDMA

   Posted by: utsav    in Tutorials

By Utsav-Goswami

most of us using optical drives and hard drives sometime or the other have to bear the

problem of the transfer mode being changed from UDMA to pio.It is very irritating because

the cpu usage shoots up to almost 100% and no multi tasking is possible.

So have no fear because UTSAV is here.

I will give a step by step tutorial to change the transfer mode to UDMA from pio without

reinstalling windows.

There are also some registry hacks so use them at your own risk.

to open registry editor goto start then click on run and type in ‘regedit’ except the

quotes. press enter.

For optimum transfer efficiency, the IDE channels should be using UDMA (Ultra Direct Memory

Access) and not PIO Mode (Programmed Input/Output). But Windows frequently decides on many

systems to use the latter.

So what’s the diff between the major transfer mode groupings? It’s most importantly about

what hardware in your system is providing the grunt for data transfers:
Mode
Explanation

PIO
Programmed Input / Output

The CPU manages the transfer of data between system memory and the storage device. Supports

bus speeds up to 16MB/sec, if your processor can keep up. Nothing built this century should

be using PIO.

DMA
Direct Memory Access

The bus-mastering system controller (a.k.a. DMA controller) is programmed to manage the

transfer, freeing the CPU to do other stuff while the DMA controller does its thing. It’ll

also support bus speeds up to about 16MB/sec.

UDMA
Ultra Direct Memory Access

A modern (I think 64-bit?) version of the DMA method. It’s the current standard for high

speed storage devices with bus speeds up to 100MB/sec.
