using the mkfs utility, I want to create the largest possible file system for the UZI180.

The command is next:
mkfs device size fsize

what values for isize and fsize are valid or optimal.

fsize 65400
isize 1090

The resulting FS size will be 32 Megs.

Thank you.

I am trying to install UZI180 on an IDE disk
As an IDE disk I use a CompacFlash SanDisk 128.

I have created several partitions using the fdisk program (as in the description)

Partition Start End Size Bytes Bootable Type
--------- ----- ----- ----- -------- -------- ------
1 1 1999 1999 16375808 Y CP/M 3.0
2 2000 3899 1900 15564800 Y UZI
3 3900 3999 100 819200 UZI swap
4 4000 5699 1700 13926400 UZI

Next, using the mkfs utility, I want to create a file system, for which I run the following command:

mkfs /dev/hda2 4802 30400

after answering a question
Making filesystem on device /dev/hda2 with isize 4802 fsize 30400. Confirm? y

I get the following messages on the screen:

..

What says that the program does not work.

I don't understand what is my mistake and how to fix it.

Which IDE interface are you using? What is the IDE base I/O address?

The FDISK program uses basically the same UZI180 low-level routines to access the hard disk, but with one difference: FDISK uses OUT0 instructions while UZI180 uses OUT. Thus if your IDE interface is decoding the A8..A15 lines of the I/O address UZI180 may refuse to work.

Another reason for failure may be the CPU speed: a 33MHz P112 is on the edge for some disks and may require inserting additional wait states, running the CPU at 16 MHz should be OK.
