Another way to get "big disk support", is to plug in a PCI IDE
card. The card must support a high enough version of the
ATA/ATAPI standard, in order to support large disks (like >128GB).
Cards of that type, will usually have a BIOS chip on it as well,
and the BIOS chip provides Extended INT 0x13 boot support.
The exception to that, is some Promise controller cards,
where the BIOS is hidden inside the main chip. If you have
a Promise IDE card of some sort, try connecting the drive
to that, then see what capacity is reported. You may need
a driver for the Promise IDE card, to finish the job.

It's hard to find good cards now, for this purpose. This
one uses an ITE 8212F chip, and has room for two ribbon
cables on the connectors.

And this card uses a VT 6421 family chip. My previous motherboard
used similar technology and seemed to work OK. If using the
SATA ports on this card, you'd insert the "Force 150" jumper
on the back of the hard drive, as the ports only run 150MB/sec.
There is one ribbon cable connector, and that is what you'd want
to use for your current problem.

I have Promise Ultra133 TX2 cards here for this purpose, but
they are no longer for sale new.

So that is another way to fix it, if this is a motherboard + BIOS
problem.

Thanks for your clarifications.
I forgot to mention it that as the BIOS
shows the capacity as 33.825 (it does not
say GB or MB) but the explorer and shell utilites indicate the correct
capacity
74.5GB of the disk.
The property tab of C: is also 74.5GB.

Does this mean that any space in access
of 33.825GB is Unusable?
If the disk is fully usuable in its present
situation then leave it as is the moment?

I don't know the answer to that. It might mean, if
this is your boot disk, and the boot partition is
positioned above the 33GB mark, it might not work.
That is the only concern that comes to mind.

I thought on some other motherboards, when they didn't
support >33GB, the motherboard could not complete POST
and boot. Since your system is working, and Windows
reports the correct amount, that sounds pretty good to me.
The only concern, would be if you placed a partition
that boots, above 33GB.

Thank you very much for your comments.
The computer is at the momennt with my
friend who is checking it.
He thinks that 33.825 is not a straight
GB or MB figure but 74.5GB devided
by clusters/cycles or something like that
of which I am not familiar.

The WinXP boots ok. No problem with
or during post. It is all C: boot partition.

I need to partition the disk into C: 20GB
and the rest D: for storage. I do not want
to take risk to loose my stuff.

Once again thank you very much for your
very valuable comments and clarifications.
