MS-7513 Mainboard Password Check You need to enter the password as you boot up or enter COMS SETUP. If you want to delete the password settings, you need to reset the password in SETUP and press to make the password place empty. Primary Graphics Adapter This setting specifies which graphic card is your primary graphics adapter. Setting options are: [AGP] The system initializes the installed AGP card first. If an AGP card is not available, it will initialize the PCI VGA card. [PCI] The system initializes the installed PCI VGA card first. If a PCI VGA card is not available, it will initialize the AGP card. PCI Latency Timer This item controls how long each PCI device can hold the bus before another takes over. W hen set to higher values, every PCI device can conduct transactions for a longer time and thus improve the effective PCI bandwidth. For better PCI performance, you should set the item to higher values. CPU Feature Press to enter the sub-menu and the following screen appears: Execute Bit Support Intel's Execute Disable Bit functionality can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system. This functionality allows the processor to classify areas in memory by where application code can execute and where it cannot. W hen a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation. Set Limit CPUID MaxVal to 3 The Max CPUID Value Limit is designed to limit the listed speed of the processor to older operating systems. 3-10

Execute Bit Support
Intel's Execute Disable Bit functionality can prevent certain classes of malicious
"buffer overflow" attacks when combined with a supporting operating system.
This functionality 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 or worm propagation.
