Umm ... safest to do the 2.5" to 3.5" drive carrier thingy ... preferrably on the
primary IDE channel of whatever computer you put it into.

See below.

Nah we only care about how many 'logical' cylinders it has. As for 15 heads, well 2
heads are better than 1, 15 just takes it that little bit further ...

Looks like you might need to remove all other IDE hard drives to do this using Windows
FDISK ... *shrug*

Umm ... well ya but what about the hibernation area? This is where the libby writes
the contents of RAM off to when it hibernates so it can restore it on wakeup ... this
area is hardcoded into the BIOS as being the highest X meg of hdd space it can see
where X is the size of RAM plus book-keeping info. Since the BIOS can see a maximum of
1024 cylinders, this area is either the highest X meg of the hard drive, or the X meg
just below 1024 cylinders, whichever is lower. The BIOS does this independant of
partitioning or OS ... which means if you have anything important there, regardless of
how you've partitioned things, it'll get oblitherated. Like I said, do the
partitioning and formatting in the libby using a DOS boot disk (with FDISK and format
on it) then move the hard drive to another computer, using the converter if necessary,
to perform the copy across of all the install files and drivers, then put the hard
drive BACK into the libby to do the actual install.

Well you can get around the card and socket services thingy if you put all the install
files and Windows drivers for your CD-ROM drive onto the hard drive using another
computer ... that way you can do the entire install with the hard drive in the libby,
and the hard drive will have all the files you'll need. This skips straight over the
DOS PCMCIA problem (Windows has its own services to get the PCMCIA slots working,
you'll just need to find the drivers for the CD-ROM drive).
Hope this helps! I'm off to bed now #-)
