Mee too now, thanks to this article ;)

That's what I did now:

BSDROOT:   19M   10233    9592  52%   0  Read/Write BFFSa
BSDVAR:    19M     825   19000   4%   0  Read/Write BFFSb
BSDUSR:   241M  150655   96968  61%   0  Read/Write BFFSc
BSDHOME:  144M      31  148440   0%   0  Read/Write BFFSd
BSDUSRLOCAL:  463M    5670  468936   1%   0  Read/Write BFFSe

That was my mistake. The initial DOSDriver was called BFFS. Later on I
changed it into SD0D (and now it's called BSDVAR). The C:Info part
above was taken before I changed it into SD0D.
Sorry for the confusion.

Do you only use 3 partitions?
/, swap and /usr?

What do you use as PreAlloc and Reserved?

btw, what is the Reserved keyword for? I changed it to several
settings but that didn't visibly change anything.

Correct. Got that as well now.
But while mounting with the DOSDrivers, it still appears only after
the first access whatever I change.

Since you didn't include 0x4e425301 ('NBS\01') for the swap aprtition,
it isn't mounted. Is there any reason why swap should be mounted?

After this exhaustive article, it also works for me.
Many thanks Stefan!
