My laptop is a Samsung NXO5. This was not made available to Portugal by Samsung. This is a very classy, lightweight and thin laptop.
- Processor: Intel Pentium M 1.4 GHz
- Chipset : Intel 82855 GM (Montara)
- RAM: 512 MB DDR
- Graphic adapter: Intel Extreme Graphics 2
- Interfaces: PCMCIA/Card Bus, USB (2x), VGA, LAN, modem, Wireless-LAN (802.11b), S/PDIF, analog sound, Memory Stick
The advised OS for this Intel Based laptop is MS Windows XP (go figure why!). I have it running in Ubuntu 5.10 (also known as the Brezzy Bagger), without any problem, every thing worked right out of the box (only the modem and the Memory Stic wheren't tested yet….)
The only problem that i found was that my Teac DVD Multi-Recorder did not had the DMA activated. So what i did was:
- On my terminal:
~$sudo hdparm /dev/hdc
- This command let's you check the state of a certain drive, in this case my DVD drive.
- Hdparm let's you get/set drive parameters (for more information check this link or wright "man -k hdparm" on your terminal).
- To execute it, you will need super user (sudo) permission.
- The /dev/hdc is the path to my DVD drive.
- you should get something like this:
IO_support= 0 (default 16-bit)
unmaskirq= 0 (off)
using_dma= 0 (off)
keepsettings= 0 (off)
readonly= 0 (off)
readhead= 256 (off)
HDIO_GETGEO failed: Invalid argument
- If you have the DMA off (using_dma = 0 (off))then let's activate it
~$sudo hdparm -d1 /dev/hdc
note: This command will enable the DMA, but you would need to do it again every time you reboot the computer, if you wanted to enable DMA.
- To activate the DMA every time you reboot the computer you need to edit the hdparm.conf file so on the terminal window:
~$sudo cp /etc/hdparm.conf /etc/hdparm.conf.enable-dma.backupnote: This command will backup the previous hdparm.conf file. This is always a good politics. Only Super User can edit the files on this OS folder , that is why you will need sudo
~$sudo gedit /etc/hdparm.conf
note: Gedit is the default ASCII text editor for Ubuntu. Something like Notepad, but far better.
- Then you just need to add this lines to the end of the file
note: the information on the file is very good to learn more about setting a drive configuration.
