I am trying to install xp in to the 160bg hdd using a cd. In the meantime the old hdd is been taken out during thr installation process. Well that's the plan but at the moment we cannot get past the POST.
Fyi when I try to connect the old hdd(40gb) as Primary master, I cant get pass POST or I think at least there is no POST. What can I try next //// Thanks

If you take the side off the computer, is it GA-6VX, or is
it another member of that family ? There may be white lettering
on the motherboard surface, identifying the motherboard.
The processor socket type (slot or square socket), may
help identify it as well.

You can try clearing the CMOS.

Gigabyte has motherboard manuals. This one is pretty small
and is only 17 pages long. I don't see mention of a CMOS
jumper in the section mentioning RTC (real time clock and
CMOS memory).

To clear the CMOS, what I would try...

1) Normally, you want to have a written record of the BIOS settings.
If any of the settings were custom values, you'll need to restore
them later. When the battery died on my P2B-S, it took me
half an hour, to remember how to set the boot order on the
stupid thing. So it helps to have recorded any settings like
that, that you may need later.

2) Turn off and unplug the computer. There is to be no power
in the chassis while doing this!

3) Remove the CMOS battery. It is a round shiny disc in a socket.
Keep track of which way it goes back, for later insertion.
If you have a multimeter, the typical CR2032 type battery
has a normal voltage of 3.0V or so. If it is 2.4V or lower,
replace it. The last one I got cost $5.

4) Leave the battery out for an hour. On more modern motherboards,
the CMOS jumper helps drain any stray power left over, and
helps to complete the reset operation. When I say leave it out
for an hour, that is my estimate of how long it would take
for capacitors and the like to discharge, on their own.

5) Reinsert the battery. Plug the computer in. Enter the BIOS
and set up any custom settings, such as boot order. On a
board of that vintage, some of the important settings are
done with jumpers, and those won't be forgotten when the
battery is pulled.

Aha! The F1A bios listed here, mentions support for up to 64GB
disks. So it has a 64GB limit. Clipping your drive, with the
clip jumper, to 32GB, should work fine with that. Using a
larger drive, shouldn't really upset anything in a permanent
way. I'm surprised putting the original disk back, has not
straightened it out.

Some old BIOS, will have a "reset ESCD" setting in the BIOS,
and that can be used to make the motherboard forget about
hardware that was just installed in it. It is a BIOS setting
(so you have to be able to get into the BIOS to use it),
you set it, and the next time the motherboard starts, the
setting is cleared. (It is a one-shot operation, which is
why the BIOS clears the setting on its own, at the same time
it clears the ESCD storage area.) This is an example of a
page that mentions it. I'm not sure that clearing the
CMOS, also clears ESCD. They are stored in physically
separate devices (ESCD is stored inside the BIOS flash
chip).
