I don't know, but AFAIK it sees what it get's from BIOS. And the
Libretto BIOS will not see the whole disk (INT13 limitations).
So you will need some kind of bootmanager, which will pass the right
table to the OS, I've heard about such a thing, but can't name one.
Hope, google will help.
EZ-Bios/EZ-Drive is one, what you need is actually called a BIOS overlay -
search the archives for extensive debate on the issue :-)
Basically it loads overrides (overlays) some of the BIOS instructions and
lets DOS-based OS's (and Win9x-ME) see past 8GB.
I doubt that W98 can _handle_ disks greater 128GiB/137.4GB(SI norm).
IIRC 48bit LBA(?) first came with ServicePack1 to XP.
That may well be the case - I'm not sure if Win98 handled 48 bit LBA.
Linux since 2.4.19 can handle them. It also doesn't read the BIOS, so
the INT13 limit doesn't show up.
Yup some of the later OS's like those >Win2k and Linux don't use the INT13
instructions so they don't need an overlay (but because the know how to
handle an overlay, until recently I recommended using a drive overlay to
allow you to boot to a DOS floppy for recovery - nowadays I just say take
the hard drive out, plug it into another box and do your recovery there).

Both i think.
Well sorta ... it's a firmware and software limitation but not actually a
hardware limitation (such as a lack of bus lines) :-)
Having said that AFAIK no-one has modded the firmware (in this case,
probably the BIOS and IDE controller) to handle the ATA limit so the
distinction is somewhat academic.

So I doubt, the 1x0ct will work with this drives. AFAIK there were
interface changes which affect the whole IDE interface (hw).
You could always do something silly like use a SATA PCMCIA card then run
wires back to the hard drive bay and somehow get a HDD and connector to fit
into the original HDD bay (should be possible with some creative
plasticwork) ... then figure out how to boot the Libretto off the SATA
PCMCIA card :-)
