There is one non-listed restriction: OS3.1 (not everyone have OS3.5+)
and older apparently do not like >65535 cylinders.
Yes. Joerg went on to say in that thread:
"I checked the old sources and release notes of FFS and the AmigaOS <= 3.1
versions had several bugs, for example it's using mulu.w (HighCyl-LowCyl+1),
SectorsPerCylinder to calculate the number of sectors on a partition, but
since mulu.w is a 16 * 16 = 32 bit multiplication that can't work ..."
Yeah, it appeared just after I had posted :)
btw, I don't agree with rejecting "illegal" geometries. The problem is
that you don't know if selected geometry is really "illegal" until it is
too late. Perhaps user has blizkick/setpatch/other hacks in
startup-sequence that adds updated driver etc..
I have learned to not reject "stupid" options. There is always someone
who needs that feature, usually using it for something totally
unexpected purposes :)
