Re: [coLinux-users] Colinux Blue Screen Crashes

[Miller, S. <sha...@yr...>]

Did you get my last message regarding possibly useful info you could share?  If not, I'd appreciate it if you could review it.

 

There are several kernels:

*	Uniprocessor, no-PAE (the default ntoskrnl.exe)
*	Uniprocessor, PAE (ntkrnlpa.exe)
*	Multiprocessor, no-PAE (ntkrnlmp.exe)
*	Multiprocessor, PAE (ntkrpamp.exe)

 

Try using Microsoft's SysInternals' Process Explorer (ProcExp.exe), highlight the System process, then choose View -> Lower Pane View -> DLLs and make sure that View -> Show Lower Pane has a check-mark.  Then scroll through the list of DLLs and observe which one matches the pattern ntXXX.exe.

 

You can be using a PAE kernel without knowing it and without the /PAE switch in BOOT.INI.

My general tab on the system properties does NOT have "Physical Address Extension".

 

You seem to be confusing PAE with DEP (Data Execution Prevention). See http://technet.microsoft.com/en-us/library/cc738483%28WS.10%29.aspx

The /noexecute switch controls DEP.

 

However DEP may only apply to windows server 2003 and not XP.

 

" The PAE mode kernel requires an Intel Architecture processor, Pentium Pro or later, more than 4 GB of RAM, and Windows 2000, Windows XP, or Windows Server 2003."

From: http://msdn.microsoft.com/en-us/windows/hardware/gg487503

According to this PAE does NOT apply to a 1gb system. It only applies to 4gb and greater systems.
