Cannot disable OS Install Mode
Our Dimension 4700 turned itself off for unkown reasons while unattended and not connected to the internet. At first it wouldn't even turn the monitor back on so we could see what it was doing. Now it is back to normal except that the OS Install Mode is enabled limiting us to only 256 ram. We go into System Setup and the option to turn it off should be in Post Behavior but it isn't there. We only find the options here for Fastboot, Numlock Key, Post Hotkeys, and Keyboard Errors. What turned this mode on in the first place and more importantly, how do we turn it off and get access to the rest of our installed ram???

If that doesn't resolve the problem then I would try a new motherboard battery. The loss of hardware configuration settings can be an indicator of the battery failing. A new 3-Volt, CR2032, coin cell battery can be purchased for around $3 (US) and is available at any Radio Shack, computer stores and most discount stores like Wal-Mart. For $3 it is a very cheap item to rule out as the cause of the problem. You can click here <ADMIN NOTE: Broken link has been removed from this post by Dell> for information on how to replace the battery from your model's on-line Service Manual. While the battery is being changed I would recommend clearing the NVRAM by the procedure I have listed below.
With the machine unplugged from the wall remove the battery from the motherboard. Then with the machine still unplugged press the On button for 30 seconds to dissipate any remaining electrical charge on the motherboard. Then re-install the battery, plug the machine back into the wall and see if it will boot normally.

Thank you Majestic! I struggled for 2 weeks with Dell Tech. Service calls on this issue and only solved it when I found your posting.
