ABIT KT7A and 137 GB issue

Hi
Need help on one subject. My mainboard ABIT KT7A does not recognise
correctly 200GB Western Digital HDD and shows only 137GB capacity. Is
there any remedy for this? Thanks for help.

Hi kingdom -

First... do you have a revision 1.0 - 1.2 or revision 1.3 KT7A motherboard.
This is significant because there are different BIOS releases for these
boards.

Do not attempt to flash the BIOS for the wrong revision board.

Look on your motherboard for a white sticker with a bar code and the KT7A
model and revision number printed below the bar code. This sticker is
frequently on the side of the last ISA slot, so you may need a small mirror
in order to read in with the motherboard in the case.

If it's a revision 1.0 - 1.2 board, BIOS version 7N introduced support for
48-bit LBA, which is required for hard disks greater than 137GB. BIOS
version 9A is the most recent, which also supports 48-bit LBA. These BIOS
versions can be downloaded here:

If it's a revision 1.3 board, BIOS version 7P introduced support for 480-bit
LBA. BIOS version B4 is the latest, which also supports 48-bit LBA. These
BIOS versions can be downloaded here:

Note: you'll also need an operating system which supports 48-bit LBA, such
as Windows XP with SP1 applied.

If you are adding the drive to an already installed XP SP1 (or SP2) system,
you may need to modify the registry for 48-bit LBA support. Instructions on
doing this are posted in the Knowledge Base at Microsoft's website. Search
for "Windows XP" and "48-bit LBA".

That's 48-bit LBA. I wonder how big a hard disk would be supported by
480-bit LBA (and how much memory...).

Sorry for the typo.
