If it works for you, please mention the model in the comments. You should use PC2-5300 SODIMM which runs at 667MHz. In order to run dual-channel mode you must have two identical memory modules in slots A and B.You can check the amount of installed RAM in the BIOS setup menu. You can use same memory type for a Latitude D820 too. One slot (DIMM B) can be easily accessed on the bottom of the laptop. Before you start, please turn off the computer, unplug the AC power adapter and remove the battery. Lift up one side of the keyboard cover with a small flat head screwdriver. For example, if you have a 1GB module installed into the slot A, you have to install an identical 1GB module into the slot B. Fortunately for us, the Microsoft Deployment Toolkit (MDT) provides a built-in mechanism for updating BIOS versions.In this How-To guide, we are going to cover: The examples shown are geared toward Dell machines.This layout should work for any Make and Model though.The only client requirements relate to the actual BIOS update file. If you are ready to get your BIOS updates under control, keep reading! In the past, we’ve covered creating a central Group Policy store and a central hardware/drive store. Before getting started, you will need a list of every model that you support.Create a new folder named BIOS Updates (or something similar).Because we only support Dell machines in our environment, my folder is simply called Dell.
They explicitly instruct 'Non-Windows users' to boot into DOS using a USB stick and to start the update executable from the DOS prompt.
Lift up the keyboard from the top cover and move it towards the display panel.
Updating BIOS versions is best done while the machine is imaging.
Dell Latitude D820/D830 can take up to 4GB memory total.
Be careful, it’s attached to the motherboard via a flat ribbon cable. The DIMM A is located just above the touch pad buttons. Now you can install a new memory module into the slot DIMM A.
