Uhm, for a Lib 100/110 62+ MB is too small a hibernation area.
Guess I wasn't clear enough about that. Thanks for pointing it out Philip. By 64MB+ I meant that the hibernation area needs to be >at least< 64MB to deal with writing memory from 64MB of RAM to the HDD >plus< a bit more to deal with bit/byte size definitions plus all else.
64 GB memory + 2 GB video mem + some BIOS stuff, rounded up to nearest cylinder boundary = 71 MB at least.
Wow.... I want the formula for getting 64GB RAM in >my< L100!! ;-P Couldn't resist playing with that type.
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....)

Then for those who like a more technical challange, there's David Chien's method of finding the hibernation area I thought was a fun learning expereince:
http://www.technoir.nu/libretto/list/2002/msg00140.html
"Create a partition that starts before 1010 cylinder and goes beyond 1040
cylinder. Download and use a free space file wipe program to zero out that
partition. Make sure hiberate to disk is on in the Power Control Panels
setttings. Open Notepad and write anything unique eg. "Librettos are SO
amazing!" Hibernate to disk (not standby), then resume from hibernate.
Walk the sectors with any hex disk editor like WinHEX to find the extent, using
search on the unique text string you typed into Notepad earlier to get you
there quicker."
