Log:
[USETUP]: Continue implementing the NT OS installation detector.
What remains to be done here, besides cleaning up the code from temporary comments and
DPRINTs (and fixing potential bugs), is to actually parse the NTOS loader configuration
files (freeldr.ini in ROS' case, or boot.ini in Win2k3's case, etc...) to retrieve
the actual installation paths. So far these are currently hardcoded for testing purposes
only.
Note that I try to distinguish between ROS and Windows installations by checking at the
company name vendor of the ntoskrnl.exe & ntdll.dll files, in order to allow the
upgrade of ROS installations only.
Suggestions are always welcome.
