Thanks.
Perhaps we could have a look at the FDISK from IBM OS/2 2.x, which claims to
be able to handle >1024cyl in some way. That's probably as close to a
"standard" as the PC world is likely to get, or at least as good a model
as anything else might be.
I may give it a try on my own system to see what it thinks of my partitions..
