请教\"NO_MORE_SYSTEM_PTES\"的具体意思？

调试程序中出现蓝屏错误，错误信息显示为\"NO_MORE_SYSTEM_PTES\"，在
DDK中的BUGCODES.h头文件中有这个宏，但是不知道具体意思。有谁知道，请多多赐教。

Bug Check 0x3F: NO_MORE_SYSTEM_PTES
The NO_MORE_SYSTEM_PTES bug check has value 0x0000003F. This is the result of a system which has performed too many I/O actions. This has resulted in fragmented system page table entries (PTE).

The system is not actually out of PTEs. Rather, a driver has requested a large block of memory, but there is no contiguous block of sufficient size to satisfy this request.

Parameters
None

Comments
Often video drivers will allocate large amounts of kernel memory that must succeed. Some backup programs do the same.

Solution
Modify the registry to increase the total number of system PTEs.

觉的还有用的话，就给点分吧。

Your answer helps me a lot,thanks
