When this item is set to enabled, PCI bus parity error (PERR) is generated and is routed to NMI. When this item is set to enabled, PCI bus system error (SERR) is generated and is routed to NMI. Press [Enter] for configuration of advanced items. PERR Generation SERR Generation PCI Express Settings - 41 - BIOS Setup 5-2-1-1 PCI Express Settings PCI Express Device Register Settings Relaxed Ordering Enable/DIsable PCI Express Device Relaxed Ordering feature. Wnen this feature is enabled, the system will allow device to use 8-bit Tag field as a requester. Enable/Disable PCI Express Device No Snoop option. Set maximum playlooad for PCI Express Device or allow system BIOS to select the value. BIOS Setup - 46 - Limit CPUID Maximum When enabled, the processor will limit the maximum COUID input values to 03h when queried, even if the processor suppports a higher CPUID input value. When disabled, the processor will return the actual maximum CPUID input value of the processor when queried. When enabled, the processor prevents the execution of code in data-only memory pages. This provides some protection against buffer overflow attacks. When disabled, the processor will not restrict code execution in any memory area. This makes the processor more vulnerable to buffer overflow attacks. Select whether to enable the speculative prefetch unit of the processor. When enabled, cache lines are fetched in pairs. When disabled, only the required cache line is fetched. Enable prefetch of next L1 Data line based upon multiple loads in same cache line. Enable prefetch of next L1 Data line based upon sequential load history. [. . . ] Default setting is Immediate.
