Greetings --
I've bad news for you, I'm afraid.
To start with, Win95 to WinXP is _not_ a supported upgrade path.
WinXP is not designed to perform an in-place upgrade from Win95. Your
only option would be to perform a "clean" installation, which entails
formatting the hard drive. Naturally, this method is
"data-destructive," so you'd need to backup any important data to
another hard drive or removable media before starting.
Secondly, if any of your DOS-based applications require direct
access to hardware resources, such as parallel or serial ports, they
will not work with WinXP. WinXP, like both WinNT and Win2K before it,
does not allow any software applications to directly address hardware
resources, such as serial or parallel ports. This behavior is by
design and is one of the reasons the WinNT family of operating
systems is so much more stable than Win9x. Other DOS-based
applications may work on WinXP, but some may not. It's rather
hit-or-miss, and you may have to experiment with WinXP's compatibility
modes.
Finally, any computer so old as to be running Win95 is very
probably composed of hardware components that are incapable of
supporting WinXP. Have you made sure that your PC's hardware
components are capable of supporting WinXP? This information will be
found at the PC's manufacturer's web site, and on Microsoft's Windows
Catalog: (
http://www.microsoft.com/whdc/hcl/default.mspx)
Additionally, you should download and run Microsoft WinXP Upgrade
Advisor to see if you have any incompatible hardware components or
applications.
You should also, before proceeding, take the time to ensure that
there are WinXP-specific device drivers available for all of the
machine's components. There may not be, if the PC was specifically
designed for Win95. Also bear in mind that PCs designed for, sold and
run fine with Win9x very often do not meet WinXP's much more stringent
hardware quality requirements. This is particularly true of many
models in Compaq's consumer-class Presario product line or HP's
consumer-class Pavilion product line. WinXP, like WinNT and Win2K
before it, is quite sensitive to borderline defective or substandard
hardware (particularly motherboards, RAM and hard drives) that will
still support Win9x.
