Cylinder 1024 bootable boundary

  Tabvla 15:16 29 May 2006

Under DOS-based Operating Systems (DOS, W95, W98) the OS had to be installed in a partition that started within the first physical 1024 cylinder boundary on the disk. This was usually referred to as the 8GB boundary but actually referred to the cylinder 1024 requirement.

Do any of the Forum members know if this boundary is still relevant with NT-based Operating Systems such as Windows XP?

Can XP be installed in ANY partition located physically ANYWHERE on the disk with the only requirement being that the partition is marked as "Active" and that the path in the boot.ini file points to the correct physical disk and partition on that disk?

I believe it still has to be within the 1024 boundary or the system will not boot
