Debian AMD64 label for its version of x86 64bit platform operating system often leads to misunderstanding that the installer only supports AMD CPU only. In fact the label was meant to support Intel based x86-64 bit CPU as well (such as the Core Duo processor) in addition of AMD machines.

Why Debian use ‘AMD64’ ?
The source of confusion traces back when AMD being the first to design the instruction set for the 64bit version of x86 CPUs (for Athlon 64) back in 2002. Back then Intel hasn’t produced 64bit CPU yet making AMD the sole vendor for 64bit x86 CPU. The Debian project elected to support this architecture with the name AMD64.

Does Debian AMD64 works on Intel Core 2 Duo CPU ?
To make the story short, Intel then produces its own x86 64bit line of CPU base on AMD design. Since there are similarities, so both AMD64 and EM64T (Intel x86 64bit) shares instruction set design practically Debian AMD64 bit works on Intel CPU too (that includes Core 2 Duo CPU)

Conclusion
Debian still stuck with the old AMD64 labelling despite x86-64 is not limited to AMD CPU only and if you are wondering which version of Debian to install on your Intel Core 2 Duo computer, then please choose AMD64 with confidence.

I’m supposed to post this post last month while the issue was still hot, but it seems that this post has been evading me for quite some time until now. Last month a friend of ours decided to get his first laptop, after browsing the internet and satisfied with our peers’ recommendation, he settled on Compaq Presario v3521 which is a relatively new model that supports SATA2.

However the joy of getting a new laptop soon fades away when he finally found out that Ubuntu does not support that particular model! The Ubuntu installer either froze up during the LiveCD booting screen or the installation dialog doesn’t detect any hard disk attached to the laptop.

After testing it with various Linux distro including Fedora, Debian, Red Hat Enterprise Linux, Solaris (ok that wasnt a GNU Linux distribution but close), It is safe to conclude that the freely available Linux distro does not support the laptop’s hardware driver. The installer will either hang, does not detect the hard disk/dvd drive or prompts for a driver CD.

Turns out to be Compaq Presario V3521 isn’t supported out from the box by Microsoft Windows XP and Vista either! According to the friend, he has no problem installing Solaris 10 and RHEL 5 Server on the laptop either. It seems the laptop requires the use of proprietary driver in order to work its hardware.

After some tweaking involved, he decided to install/use Debian 64bit on the laptop using network install, luckily besides the bumpy installation process, every other aspect of the hardware is working with the right drivers in 64bit mode.

So for all of you out there, please watch out for Compaq Presario v3521 model, it might not be for those with a faint heart.

p/s: It true, though Ubuntu seems to be easy enough to use, it might not be the best solution for you. It still has some rough edges, particularly with x86-64bit platform.

Here’s the way to configure Ubuntu to autostart your favorite application upon startup (like Microsoft Windows ‘Startup’ folder). This how to assume you are using the default GNOME windows manager.

• From the Desktop, Go to System > Preferences > Session,
• Select Startup Programs, click “New”, and type in the command of your favourite application. Close the tab.
• The application selected in the Startup Program dialog should automatically starts the next time you logged in your computer.


Why do you need Startup Programs ?
For convenience purposes. with Startup programs, you don’t have to manually launch your favourite application each time you logged into your Desktop environment which can become very laborious.

This is very handy if you have a list of application that you need to start each time you log in to your Desktop such as Gaim/Pidgin, Ekiga, Feedreader and/or some application that you can’t live without.

With Startup program, you can save your time from having to start these applications manually and save yourself from forgetting to start essential application each time you boot up your computer.
