virtualization technology, disabling Intel Hyperthreading, enabling processor cores, and enabling
Intel Virtualization Technology.
To access processor options:
• From the System Utilities screen, select System Configuration→BIOS/Platform Configuration
(RBSU)→System Options→Processor Options.
Depending on your server model, options can include:
• “Protecting a System from Viruses” (page 23)
• “Enabling Virtualization Technology” (page 24)
• “Disabling Intel Hyper-Threading” (page 25)
• “Disabling Processor Cores” (page 26)
• “Setting Intel Turbo Boost Technology” (page 27)
• “Enabling Intel VT-d” (page 28)
Protecting a System from Viruses
You can protect as system against malicious code and viruses. Memory is marked as non-executable
unless the location contains executable code. Some viruses attempt to insert and execute code
from non-executable memory locations; these are intercepted and an exception is generated. Your
operating system needs to support this option.
To protect a system from viruses:
1. From the System Utilities screen, select System Configuration→BIOS/Platform Configuration
(RBSU)→System Options→Processor Options→No-Execute Protection and press Enter.
2. Select one of the following options:
• Enabled (default)
• Disabled
