IMM small outline dual in line memory module chip the amount of memory per area on chip is doubled Hence instead of the system maxing out at 4GB RAM it actually is able to give the system double which is the reason for the 8GB in total The machine in front of me has 2GB of memory which will be thoroughly tested later on but standard configurations are 2GB or 3GB of memory This should be more then enough for the average user the only times in question when one would need such high memory is when running multiple multimedia applications or a programmer looking to build a large scale program or run multiple VM s to test the inter compatibility of their source code on different platforms Hard drive space is ample at 160GB although a choice of 160 or 320GB SATA I based drives is available in standard off the shelf configurations for this model This is especially handy as if not using a network based file share such as NFS or SMB for Windows users one can store pretty much all their work related files on the drives with either space to spare in the long run over many years or alternatively can keep multiple concurrent backups of each file folder Another point is that if dealing with rather large files such as video files or VDI images again there is plenty of room to store many of them and the host based operating system too Alternatively one can multi boot the machine and have enough room for 2 3 host based operating systems with many further guest

21. development not everyday use This leaves me with Ubuntu which is a Debian derived operating system and shares a lot in common with Debian but having the advantage of more up to date packages and kernel which are totally stable For the last few months I have been running Kubuntu 9 04 which is based on Ubuntu 9 04 Jaunty on all my desktop based systems and since it has a 64 bit edition this seems like an obvious starting choice I actually think this is a good choice for a wide range of users as Kubuntu will appeal to basic and more experienced users alike 3 1 Install The install of this system went very smoothly and was very fast too The Intel based GFX controller although not recognized 100 by the system didn t have any problems in reverting back to Intel 1915 compatibility This of course resulted in the system only being able to achieve SVGA quality at 1024x768 resolution but since this was only for the GUI based installer it wasn t really that important an issue I always like to use a custom partitioning scheme when I do any install unless it s MS based where in which I usually just have everything on the C partition For UNIX systems I maybe dealing with multiple partitions and or slices depending on the filesystem format but however in this case I am going to restrict myself to simply ext3 The system comes with a 160GB HD which is more then enough for what I am going to use it for with a single OS based install seeing as I always w
22. discussed That leaves us only with the networking capabilities of the system which again are nothing short of impressive A Bluetooth 2 0 EDR 3 radio for connection to PAN personal area network devices such as cell phones PDA s wireless headsets etc The Intel 802 11 interface has dual radios which operate at the 2 4GHz and 5GHz frequency ranges This means a b g and n draft compatibility so this notebook can connect to any wireless access point WAP even in the United States of America as the 5GHz range is the preferred operating frequency out there while 2 4GHz is preferred in the rest of the world Also security abilities of the Intel IPWS5100AGN are completely business class offering backwards compatibility with WEP based networks but also being WPA and WPA2 enterprise compatible The 802 3 interface is a standard 10 100 1000 full duplex NIC network interface card so nothing special to write about here other then I would be worried if it didn t operate at 1000Mbps as this is now the standard for all NICs of today Last but not least and something which I think is hardly ever used today is the V 92 56K modem but it is still there for compatibility when 802 3 802 11 and 802 16 networks are not available 3 Operating system usage and capabilities Now that we ve discussed the system s internals and externals let s have a look at actually installing and running an operating system on here It is going to be interesting to see the l

25. evel of specific hardware support Based on my previous experience with my older laptop the Hi Grade which is now about 5 6 years old running Debian 3 1 Sarge Linux on there meant that I had to hack the system out quite a bit in order to gain compatibility for the IPW2200 wireless controller and the Intel 855GME based chipset too This meant installing the kernel driver and firmware for the Intel Pro Wireless 2200 NIC and 855 or 955 resolution for the i810 based Intel 855GME chipset in order to gain proper screen resolution of 1280x800 which without defaulted to SVGA resolution of 1024x768 superimposed upon the 1280x800 based screen area causing visuals to be stretched and squashed As a UNIX engineer I could run any operating system on here from any of the following Linux Solaris BSD AIX HP UX and IRIX Unfortunately AIX HP UX and IRIX are all proprietary and I do not have access to them Instead however BSD Solaris and Linux seem much more viable options I must admit the decision is a bit hard as they re all really interesting platforms but since Linux is probably the best OS out there for a desktop platform having an amazingly high number of applications which are not just free but very powerful too it seems like the best option to go for at the moment The key element now is to select a distro which is going to be pretty tough as there are so many out there with varying levels of hardware support Due to the newness of the Intel chipset an
