Lenovo T400 Blue Screen issues and resolution

I got my Lenovo T400 last Christmas. However, Windows gave BSOD intermittently. Turn out it is the video card causing all these issues. I follow the link http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-71851 I turn off Aero and the switchable graphic card in the BIOS. Instead just use the ATI graphic card. There is no more bluescreen after that. Note: Check back on the site today and see there is an updated drive posted on April 28, 2009.

Archiving and backup (DiskXtender)

A lot of my customer cannot distinguish between archiving and backup. They think archiving is the same as backup as well as safe them space on primary storage. This is wrong. Archiving is a process of moving inactive or infrequently accessed data from primary storage to other cheaper storage. For example, moving from a lun of Symmetrix to Centera. If settings in Centera are correct, it can reduce duplication of data being saved on the target. Backup will save a secondary copy of information. Archive only moves the data to another storage media. You still have only one copy of the data. Use EMC DiskXtender as an example, if files are moved to secondary media and rules are setup properly, files that were moved to secondary storage can now be purged from the primary storage and leave a shortcut on the primary storage. The shortcut contains info about the location of the file in the secondary storage. When you click on it, the program will fetch the file back from secondary storage. You ca

Installing Solaris 10v x64 bit on VMWare Workstation 6.5.0 Step By Step

To install Solaris 10v x64 bit, make sure your CPU is 64 bits with VT enable in BIOS. Even you run the Processor Check for 64-Bit Compatibility and the result is compatible, it may still fail because VT is not enable in BIOS. For my T400 laptop with Intel 9400, press F1 to goto the BIOS (Config -> CPU). Enable the following settings Intel (R) Virtualization Technology Intel (R) VT-d feature Save Settings -> Poweroff -> Startup I have VMWare Workstation 6.5.0 installed on Vista 64 bits Business. When I install Solaris as a guest OS, it will attempt to install as 64 bits. It goes flawlessly. After installation completes and reboots, you should see it start at 64 bits. If you miss that, run isainfo -v (not uname -a). You can see that this Solaris machine is capable of running 32-bit as well as 64-bit applications. P.S. The media I use is Solaris 10 update 5. Please check VMWare website for OS support.

Wireless on T400 running CentOS 5.4

Finally, I forced myself to learn Linux by formatting my laptop and installed CentOS 5.4. Only leave an old and slow desktop for vpn. Everything runs fine except the wireless. Google and find Kurt's blog (Thanks Kurt). Steps: First make sure the RPMForge repo is installed rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm yum clean all yum update Next install the driver for the PRO/Wireless 5100 AGN[Shiloh] card from Intel yum install iwl5000-firmware The wireless device should now be working, and you can enable the NetworkManager to start using it chkconfig NetworkManager on service NetworkManager start and you may want to save yourself some wait time at boottime by disabling the network since you don't need that anymore chkconfig network off Next you need to configure your wireless connection settings by going to System > Preferences > More Preferences > Network Connections
