Although I am still unable to use the pc as it has another set of problem as during the installation or window setup, an error message "file setupdd.sys could not be loaded. The error code is 4.

I have a copy of the i386 folder from the CD, and
SETUPDD.SY_ is in that folder. So the install is
having trouble copying that file over. I believe
the underscore means the file is compressed and
the installer will take care of the details.
Sounds like maybe you're having trouble either
reading the CDROM, or any amount of heavy data
traffic on the cable results in corruption or
something.
So how are the drives cabled and jumpered ? Are the
HDD and optical on a single cable ?
When I installed WinXP, I did mine using a hard drive
install. (I did this purely for fun, because I heard
you could do it that way.) What that means, is I created
two partitions on my 80GB IDE drive. The first partition
is 78GB and the second is 2GB. In the 2GB partition, I
copy the contents of the i386 folder of the WinXP CD.
The trick then, is to use that folder to complete the
install. The procedure requires a second computer,
to prep the drive and copy the files from the
Windows CD.
When creating the partitions, it is important to
create the 78GB partition first (so it is the first
entry in the partition table), and the 2GB partition
second. (I determined that empirically, getting it
wrong the first time.) The partitions should be FAT32,
for the purposes of being able to access the partitions from
DOS. The first partition could be converted to NTFS
later if needed (with "convert"), but I didn't bother.
The basic concept is outlined here.

It took me a good part of the day, to cook up a
MSDOS floppy with the necessary files to do what
was required. Including SMARTDRV supports caching
when accessing the disk, and that makes some
improvement to the process. But considering the time
I wasted, I'd be happy to just let it chug along
at 1MB/sec if it wanted, because the caching wasn't
that smart after all.
This is my autoexec.bat on the MSDOS floppy . The
numbers are "cranked", because I was experimenting
with getting the best disk to disk transfer rate possible.
I think I added the MSCDEX stuff later, when I added
support for CDROMs to the floppy (to make it a better
all-round recovery floppy). The "pause" is so I could
read the screen.
mscdex /D:MSCD001 /L:R
pause
a:\smartdrv.exe /V 32768 32768 /E:32768
This is my current config.sys. I've since added
CDROM support to my MSDOS boot floppy, and I downloaded
XCDROM because oakcdrom wasn't working. The "?" in
the first three lines, causes the floppy boot process
to pause. Hitting return lets it continue. I was getting
stuck at the EMM386 step, and had to manually experiment
with the "X" parameter, until I no longer had a resource
conflict. On many attempts, the floppy boot process would
get stuck with the floppy light on, which means the
hardware was being trampled by something being loaded.
The last four lines are pretty standard stuff which
I didn't bother changing.
DEVICE?=HIMEM.SYS /TESTMEM:OFF
DEVICE?=EMM386.EXE NOEMS X=A000-CFFF
DEVICE?=XCDROM.SYS /D:MSCD001
FILES=20
BUFFERS=20
DOS=HIGH,UMB
STACKS=9,256
My boot floppy started from one made from Win98, and I
added stuff to taste, like a pot of stew :-)
The install ends up being not much faster than doing
it straight from the CDROM. But, if your CDROM
is having problems, the DOS floppy plus hard
disk partition trick, is an alternative installation
method. Naturally, you still need to fix your CDROM,
but if you're living in the woods, and a new CDROM is
a week away, it gives you something to do in the
interim.
Depending on whether you have a broadband Internet
connection, you could also consider experimenting
with Knoppix (Linux LiveCD) from knopper.net. That is
a 700MB download for the CD version, and all you
need in this case, is the latest CD version, as
the DVD version is too big to be practical.
As a test mechanism, Knoppix gives you
1) No need for a hard drive. It runs straight from the CD.
2) At boot time from the CD, Knoppix gives you boot
time options. Memtest is one of them, allowing
you to test system memory. In addition, Knoppix
has an integrity check boot option, which causes
the checksums of the files on the CDROM to be
verified. If any of those verifications fail,
you know you have a CDROM drive problem (or
bad media). So that makes a quick way to verify
the CDROM drive is good and the cables are OK.
It isn't much of an OS, but as a means of doing
hardware testing, it is a great alternative. But
only feasible if you have some way to download
a 700MB ISO9660 file and burn a bootable CD
with Nero or something.

Paul
