Any SDHC card between 4GB and 32GB should work fine. Also non-SDHC
cards (2GB and lower) should work too, but I haven't tested that as
much. I use Kingston cards and never had any issues with them,
otherwise Sandisk is generally recognized as a good brand with quality
cards.

Note that FUZIX requires you to unmount the file system cleanly before
powering off. The recommended way is by running:
 telinit 6
and wait until it displays "Halted.". If not, you will be prompted to
do run a file system check (fsck) the next time it boots up, and this
takes forever so you really don't want to do that. These are
"features" of FUZIX (and many old UNIX systems).

It has nothing to do with 256 versus 512 bytes sectors, because the
NitrOS-9 system uses the rbsuper high-level driver to convert sectors.
