Meaning
|
|---|
0x0 | The system calculates an optimal number of page table entries based on the platform type and the amount of memory available to the system. The system adjusts this value if the amount of memory changes. |
0x1–0xFFFFFFFE | Specifies the number of reserved page table entries. This value takes precedence over the system's calculated value, and it prevents the system from adjusting the value. |
0xFFFFFFFF | Maximize system pages. The system creates the largest number of page table entries possible within physical memory. The system monitors and adjusts this value dynamically when the configuration changes. |
Caution
-
Do not change the value of this entry. Changing it prevents the system from calculating an optimal value for your system and adjusting the value when your system changes.
