Uhm, for a Lib 100/110 62+ MB is too small a hibernation area.

64 GB memory + 2 GB video mem + some BIOS stuff, rounded up to nearest
cylinder boundary = 71 MB at least.
That makes for:
*** start:
cylinder 1017 or 8.350 (according to SI standard 1 GB = 1000,000,000
bytes) or 7.775 if you prefer powers of 1,024 bytes
*** until
cylinder 1026 or 8.480 / 7.895 GB
(at least those numbers work with my Lib. I also got a Hitachi 7K60
inside there).

(I have no special preference for base 1,000 or 1,024, but sure there
*is* a standard and anyway one should at least make clear what kind of
KB / MB / GB is referred to if not obvious at first sight. Above, 64 MB
RAM is obviously base 1,024 but IIRC Microsoft FDISK reports in real
bytes (=> so you end up in SI standard) while other tools just report MB
base 1,024)
(The best option is to not use FDISK but use a partition tool which
partitions in cylinders rather than MB. Microsoft FDISK is the only
partitioning tool which allows partition boundaries to *not* coincide
with cylinder boundaries, although there is no operating system which
can cope with that properly. Indeed, even MS FORMAT seems to assign
"unused" parts of cylinders to bad blocks....)
