[Dev-C++] General Windows thing

[Kenneth A. <dig...@ho...>]

i have a question that doesn't involve Dev-C++.  If you have two physical 
hard drives and you had (just for the hell of it) 3 versions of Windows, 
such as Me, XP, and 2000 Pro.  How would you set up the hard drives to store 
and read information from both drives with all OS's booting off of one 
drive.  I believe that 2000 Pro uses a different file system and I know that 
both hard drives would have to be partitioned to be able to have all of the 
OS's bootable.  What would be an effecient set up for this?     digimars

Windows XP and 2000 support both NTFS and FAT32. In the Me, 2000, XP
situation with 2 HDDs you create 2 partitions in the one HDD and 1
partition on the other. Each OS will be in its own partition. First you
install Windows Me in one partition, then Windows 2000 in another and
then Windows XP in the last. If you want to be able to see the contents
of every partition from within the 3 Oses you will format all partitions
with FAT32. But i can't see a reason why you want 3 windows (or 2) on
the same machine. Myself have Windows and Linux on the same machine.

Compatibility testing.  If you have code that enables certain features 
based on the OS or is supposed to be functional across different versions 
of windows, you don't know if it works unless you can test it.  I have a 
friend who has a Mac computer with every major version of the Mac OS on 
several hard drives to backward test his programs.

Yes but MAC OS is a different story since MAC OS X is an operating
system based on UNIX and previous versions were a different thing. In
Windows 95 and above the system libraries are the same (e.g. MFC, Win32,
DirectX) and there is no way a program written using these common
libraries to not run in any version. With this logic we should have
Windows 95, 95B, 98, 98SE, Me, NT, 2000, XP on the same machine. :)

That assumes that every previous version of Windows has an updated version
of the common libraries, or your code uses functions that are common to
all previous versions.  If your program is spec'd to be useable on
different versions of Windows, you will find it necessary to test on a
multiboot machine or use hard drive images.  If all you care about is
running your program on the latest and greatest OS, then previous versions
of the OS doesn't matter.

The libraries (=C/C++functions and classes) are part of the compiler and
not the OS. They are updated by every new version or service pack of the
compiler and they are different among various compilers (e.g. Borland
uses VCL, you can choose to program in opengl instead of directx
e.t.c.). The source code of these libraries gets compiled and the exe is
produced. The exe runs the same way on every win32 system. The same
applies for any OS. An exe that runs on dos 6.22 should run in all dos
versions. The exe will not run only in the case of a radical change,
that is the OS wants a different type of EXE.
