No

This was an attempt to add sector sizes other than 512 to the bochs image files.

Microsoft says at http://support.microsoft.com/kb/923332 that soon there will be larger sector sizes.

I got as far as the harddrv. and hdimage. files along with config.cc and the param_tree.txt and bochsrc.txt files. However, I currently do
not have a way to build the bios. Therefore, I stopped there. If someone else would like to modify the BIOS files to support larger
disk sizes, please do.

I did not work with any of the code other than mode=flat images. You will have to modify the other type of images to make sure they
work also. bximage.cc will also need to be modified.

Anyway, take this as you wish.

    yeah

    Hard disk drive manufacturers will soon start producing hard disk drives for
    which the physical sector sizes are larger than the traditional 512 bytes per
    sector. For example, sectors may be 1 kilobyte (KB), 2 KB, or 4 KB.

    yeah

    This change will enable manufacturers to improve the capacity

    Nonsense. LBA 48 and 512 Byte's per sector -> 5^57 Byte's AKA 127 PiB size limit
    .. anyone has a problem with it ???

    the performance, and the reliability of their hard disk drives.

    evidence please

    This article discusses Windows Vista support for large-sector hard disk drives.

    yeah
