Linux seems to probe the translated geometry of 1024/63/255
rather than the actual BIOS geometry of 19516/16/64 (which
is also the physical geometry) or the official translated
geometry of 1244/63/255. I use fdisk's extended commands to
set the number of cylinders to 1244 and partition as normal.
However, disk druid is invoked afterward to set the mount
points, and it then crashes when is discovers that there is
-1934Mb of available disk space.
As a workaround, I have created my last partition as a
primary partition rather than a logical partition, and have
left its end point as 1024. I will extend it later after
boot time.
