[Coco] I'm missing something obvious

I was able to obtain a couple of 1gb CF cards for use in my SuperIDE in my
CoCo3. I do have several SDC pack that work very well, so this is more of a
‘wanting to explore’ type of thing.


I have done these steps to try to use these cards.

1) Run the IDEPROBE.BAS program which says the CF cards have this
configuration:

1966 total cylinders; 16 heads; 63 sectors per cylinder, 1,981,728 total
sectors and the card supports LBA mode.

2) Run the WIZARD.BAS program and provide these inputs: base address FF50,
total sectors 1,981,728, 512 bytes per sector, 256 HDB virtual drives and
LBA mode. The output is: OS9 capacity 888.89mb, HDB capacity 78.75mb, with
an HDB offset of: 1BC720

3) I create the ROM and the BIN file via the WIZARD.BAS program

4) I flash the ROM image into bank 2 of the SuperIDE

5) Reboot the system using the SuperIDE and enable floppy drives (POKE
&HFF7F,3)

6) Use the FMTALL.BAS program to format all 256 virtual drives

7) Create a 6809 Level II, NitrOS-9 3.0.0 35 track SSSD floppy and copy
that disk to drive 255

8) Run LINK.BAS to link drive 255

9) As /i0 is not yet formatted, I use an 80 track DSDD disk to boot into
NitrOS-9. The DSDD has RBSUPER, DD_I0, etc

10) When I execute dmode for /I0 it shows: nam=I0, mgr=rbf, ddr=rbsuper,
hpn=07, hpa=FF50, drv=00, stp=00, typ=81, dns=00, cyl=007F, sid=40, vfy=01,
sct=0020, t0s=0020, ilv=01, sas=10, wpc=00, ofs=0000,rwc=00


So the information from dmode does not match the size of the OS9 drive.
Thus my question is what /I0 setting do I need too change via dmode?
