文章作者：Junxiu LeeIntel 915芯片组内置的Execute-Disable Bit capability与某些第三方软件发生冲突症状描述：
安装第三方防火墙软件CyberArmor后，系统启动蓝屏，具体信息如下：
STOP: c000021a (Fatal System Error)
The Windows Logon Process System process terminated unexpectedly with a status of 0xc0000005 (0x0000000 0x00000000). The system has been shut down.
通过安全模式进入系统后，卸载该软件后，症状消失，可以正常进入系统。
解决方案：
进入BIOS Setup |Advanced | CPU Features |找到与 "XD Bit functionality"相关的选项，将其设置为Disabled。
原因分析：Execute-Disable Bit capability是 Intel 915芯片组中新增的安全特性。
Execute-Disable Bit capability is a robust hardware feature, detectable using the CPUID instruction, that protects against malicious software executing code on IA-32 systems. Fundamental software support for this capability includes enabling Physical Address Extension (PAE) functionality and defining a memory-protection policy that is granular down to the page level.
