The early ASUS Eeepc 900 Series machines run noticeably better with the latest BIOS update.  Better battery performance, lower heat on the unit, better overall system stability.  Changing the BIOS can be tricky on these machines if you have installed Windows Vista, Windows 7 or even XP Pro as you need to install the ACPI driver before you can use the automated BIOS updated. I had lots of trouble locating the ACPI driver that worked on this model so I decided to post it on the web.
ACPI Driver for EEEPC 900 (Zip File)
To use this driver for Windows Vista and Windows 7 you will need to change the setup program to compatibility mode of Windows XP SP3 or SP2.

This update utility will also work in Windows Vista and Windows 7 but you will need to run this also in compatibility mode XP SP3 or SP2.
I have run across this issue from time to time when removing spyware and viruses off of a windows XP machine.  In the past I have been so frustrated at this problem that I ended up reformatting and installing an OS.  The good news is that this problem is now easily fixable with free tools available online.  First off this problem is typically caused by malicious software altering a specific registry key.  This Registry key is
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Under this there is an entry for Userinit
What typically happens is that although the virus software has removed the offending software this value is left set at
Userinit = C:\Windows\System32\Winlogon82.exe  (or some other virus)
This value needs to be set to
Userinit = C:\Windows\System32\userinit.exe
The tricky part now becomes how do you adjust the registry of a windows machine that will not allow me to login even in safe mode.¬¨‚Ć There is where the Offline NT password and Registry editor becomes useful – visit http://pogostick.net/~pnh/ntpasswd/ and download and burn the a CD boot image of this product (or floppy boot image if you have an old school machine).
Or you can download directly from here below – T his is a Zip file of the ISO.
Offline NT Password and Registry Editor Version 080802.zip
This version allows you to view and change the registry from a command line – simply navigate to the affected key and then change with the value listed above and the problem is fixed.
I was at Sam’s Club the other day and saw a Demo HD television playing the Blue Ray movie “TinkerBelle’s Lost Treasure”.¬¨‚Ć Although I was not impressed with the movie I was completely impressed with the picture quality of a Blue Ray playing at full 1920 x 1080 playback.¬¨‚Ć Having lots of old computers and computer parts in my home along with a newer HD Samsung television I decided to try and build a HTPC that could playback Blue-Ray’s in full capacity, hold my personal media collection and stream Netflix Movies at the highest quality settings possible.
To work with I have an older Dell Dimension computer that has the Intel 915 Chipset and Pentium 4 hyperthreaded processor set at 3 ghz.¬¨‚Ć With this Intel Chipset upgrading the processor to Dual Core or Core 2 Duo was not possible so I am sticking with the Pentium 4.¬¨‚Ć After reading review after review of Video cards I came to the conclusion that the ATI 4670 Graphics board was the best fit – having 300 stream processors, an HDMI output and full digital audio.¬¨‚Ć This card also is capable of off loading the CPU intensive task of decoding Blue-Rays and providing a full 1920 x 1080 resolution on my Samsung HDTV.¬¨‚Ć If you had a more robust processor you could probably get away with using the ATI 4350 which costs only around 40$, in my case I needed a step up to make up for my aging system.¬¨‚Ć There seems to be some disagreement on the internet as to whether a Pentium 4 can handle Blue_Ray playback,¬¨‚Ć I can say from experience it can handle it perfectly if you are using it in conjunction with a robust video card (pci-e).¬¨‚Ć For the Operating System I went with Windows 7 Pro as this OS offers great performance, slick interface, and is fully compatible with the ATI graphics Card.
75.00$ on new egg  http://www.newegg.com/Product/Product.aspx?Item=N82E16814125277&cm_re=ati_4670-_-14-125-277-_-Product
For Memory I eeeked out having 2 gigs of total RAM at 800 mhz – in addition I added a 2 gig flash drive to the back of the machine and dedicated it to Windows Ready Boost for faster caching.
For the Blue Ray Drive I purchased a 67.99$ unit on Newegg.com.  This drive comes with PowerDVD version 8 with Full HD and Blue-Ray playback capability.
One tricky element or having a working HTPC in the house is configuring a remote to use the machine.  Here I suggest two options: a friend of mine showed me a Iphone Ipod application called Air Mouse.  This easy app lets you control the HTPC with an IPOD or IPHONE and works well.  Since I use this HTPC to surf the web I decided to also try a extended range wireless keyboard and trackpad.
I chose this Adesso model off of newegg and have been very happy with its function.¬¨‚Ć Works from easily 35-40 feet away from the television – responsive, small, easy to type.¬¨‚Ć The only downside was it was a little pricey at $85.99.¬¨‚Ć http://www.newegg.com/Product/Product.aspx?Item=N82E16823166047&cm_re=addesso_wireless_keyboard-_-23-166-047-_-Product
Just a note: watch out for cheap wireless keyboards and mice from Logitech (and other brands), if you check the range on most models available at retail stores like Wal-Mart it maxes out at around 5-6 feet.  In my opinion a wireless keyboard with a six foot maximum radius is worthless.
Finally Adding a wireless pci card (could use a USB one as well) this unit connects to my Home Network.¬¨‚Ć With the Network Connection and adjusting the visual settings on Windows 7 for best look on a televsion (larger icons, text, ect) everything is set.¬¨‚Ć Honestly the frequently used feature of the HTPC is streaming Netflix – using this computer to stream netflix results in a much clearer and contrasted image than streaming from Xbox or Playstation 3.¬¨‚Ć With a $8.99 a month subscription you get unlimited movie streaming which equals 70,000 available movies and television programs – A Super Redbox in the home.
For Storage I installed an Internal 1000 Gigabyte RE3 Western Digital Sata drive.¬¨‚Ć This is a server class drive (5 year warranty) that is fast, reliable and not too expensive.¬¨‚Ć Again at newegg http://www.newegg.com/Product/Product.aspx?Item=N82E16822136313 159$.¬¨‚Ć With a sizzable collection of children’s television shows and movies stored on DVD – I simply copied all of them onto this massive hard drive making it an all in one media center.
Main uses of the HTPC
Stream Netflix (This is outstanding)
Play Blue-Ray movies in full 1920×1080 resolution
Stream Digital Music from Pandora.com or Playlist.com
Play MP3/Music Collection
Store and Display family photos
Run Boxee – Vast collection of online video streams
As many people know by now, XP does not like it when significant hardware changes take place in a machine.¬¨‚Ć If you have every tried swapping a motherboard or moving a hard drive from one computer to another you have probably seen the BSOD (Blue Screen of Death).¬¨‚Ć To move a Hard Drive with XP installed and fully intact you need to do the following. This trick will work even if you are changing processors – Intel to AMD – you just need to follow one extra step if this is the case.¬¨‚Ć This is a great trick to quickly move an entire system installed on Hard Drive to a new machine.
1.  On the old machine start wincows and edit the REGISTRY  (Start | Run | regedit)
2.  In the registry navigate to HKEY_CURRENT_CONFIG > SYSTEM > CURRENTCONTROLSET > ENUM
Now Delete the entire ENUM registry key.
3.  Shut Down this Computer
4. Transfer Hard Drive to New computer and then turn on.  The new computer will reboot a few times until it rebuilds the registry on the new machine.  If you cannot get it to boot (You see Blue Screen of Death) and you have switched from an Intel Processor to AMD you will need to do the following.
(Do these extra steps only if you are getting BSOD caused by switching from INTEL to AMD).  Boot into Safe Mode.  Edit the registry again and this time go to.  Locate and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Intelppm

As I was working on adding storage space to an my Apache based web server I ran into a small problem.¬¨‚Ć Having some familiarity with UNIX I had always been able to add more storage space or redirect folder locations by creating a symbolic links inside of the htdocs folder.¬¨‚Ć I setup the gcsdblogs.org webserver on a Windows 2003 server based machine which means – no symbolic links.¬¨‚Ć Well thanks to google I found out that Microsoft does support a very similar feature in their NTFS 5.0 file system, calling symbolic links to folder locations by the name of¬¨‚Ć Junction Points or Mount Points(entire volume).
Using a nifty free program called Junction Link Magic you can easily create almost the equivalent of a symbolic link with an easy to use GUI interface.
In this example I am using a Junction Point to add a new folder called Music to my Apache webserver,   this folder resides on a different disk with 200 free gigs of space.  Since my original Apache configuration was installed on a volume with only 40 gigs of space this is a useful way to add disk space without attempting to resize a partition.
