Execute Disable Bit: None or Off? (D620)
Getting ready to buy a D620, and there is no explanation on the ordering page about what "none" or "off" mean. I have searched these boards, dell.com, the web, UseNet, and while I find some explanations of what Execute Disable Bit is, no mention of "none" or "off"
Any help would be appreciated. I am guessing this is simply a default they set in the BIOS, and can be changed?
Thanks!

Execute Disable Bit is an Intel Technology.
From Intel's website:
Intel's Execute Disable BitΦ functionality can help prevent certain classes of malicious buffer overflow attacks when combined with a supporting operating system.
Execute Disable Bit allows the processor to classify areas in memory by where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage and worm propagation.
Replacing older computers with Execute Disable Bit-enabled systems can halt worm attacks, reducing the need for virus-related repairs. In addition, Execute Disable Bit may eliminate the need for software patches aimed at buffer overflow attacks. By combining Execute Disable Bit with anti-virus, firewall, spyware removal, e-mail filtering software, and other network security measures, IT managers can free IT resources for other initiatives.

This seems odd, what is the difference between none and off?
Thanks!
