Linux, OS/2 and >1024 Cylinder HDDs

From Tim Smith (tzs@u.washington.edu):

Some people have had Warp report that their partition map might be corrupt when trying to install on a disk that has Linux partitions. I may know one of the reasons. Warp and Linux disagree on how to denote cylinders above 1023 in the partition map.

Warp thinks that the cylinder field in the partition map should be min(1023,cylinder). Linux thinks that the proper value should be cylinder%1024. (Anyone happen to know what NT thinks?)

For cylinders >= 1024, these values will usually disagree.
