OK going back in time a little I'm currently on bios rev 1012 and I am
trying to use a 250GB HDD which seems fine under XP operating system but
reports only 85GB or so in the bios. There is a beta 1014 does this do
anything for larger drives?

You could try a PCI IDE card, like this particular one.
IDE chips designed for ATA133 rates, also happen to include
the large disk addressing mod (they were introduced in the
same ATA/ATAPI specs).

AFAIK, you will also need SP1, to get large disk (48bit)
addressing in WinXP. The smoothest way to do this, is to prepare
a slipstreamed installer CD. Looking for "autostreamer" in
Google, will take you to sites like this. Basically,
a tool like that, takes your WinXP CD and a copy of SP1,
and rolls them together. Burning the resulting .iso gives
a slipstreamed install CD.

There is info here, but ignore any adverts suggesting you
buy a BIOS from them. (I have to mention this, when I found
out that someone from here was suckered into buying one of
their BIOS.)

Also, few people will pay attention to this, but I recommend
filling a large volume past the 128GB mark, to test that the
disk address does not "roll over" at the 128GB mark and write
data to the 0GB mark. If any system component continues to
have 26 bit addressing, the disk gets corrupted, when a
write to 128GB+, is redirected to 0GB+ (modulo 26bit
arithmetic). That is the main danger with moving disks
between 26 bit and 48 bit addressing systems. Filling the
disk with 1GB sized files, is a way to prove that future
corruption is not staring you in the face. (There may be
more intelligent ways to conduct this test, but brute forcing
it is intuitively satisfying.)
