Re: Boot.ini Switches



The /forceresetreg switch looks suspect to me. If it were me, I would
remove the /forceresetreg switch.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP
Professional" /fastdetect /NoExecute=OptIn

/NOEXECUTE
[[This option is only available on 32-bit versions of Windows when running
on processors supporting no-execute protection. It enables no-execute
protection (also known as Data Execution Protection - DEP), which results in
the Memory Manager marking pages containing data as no-execute so that they
cannot be executed as code. This can be useful for preventing malicious code
from exploiting buffer overflow bugs with unexpected program input in order
to execute arbitrary code. No-execute protection is always enabled on 64-bit
versions of Windows on processors that support no-execute protection. There
are several options you can specify with this switch:
/NOEXECUTE=OPTIN Enables DEP for core system images and those specified in
the DEP configuration dialog.
/NOEXECUTE=OPTOUT Enables DEP for all images except those specified in the
DEP configuration dialog.
/NOEXECUTE=ALWAYSON Enables DEP on all images.
/NOEXECUTE=ALWAYSOFF Disables DEP. ]]

A detailed description of the Data Execution Prevention (DEP) feature in
Windows XP Service Pack 2, Windows XP Tablet PC Edition 2005, and Windows
Server 2003

What's the new /NoExecute switch that's added to the boot.ini file after you
update a machine to Windows Server 2003 Service Pack 1 (SP1) or Windows XP
SP2?
