where else is the value limited? I always thought it is very flexible
compared to C/H/S driven IDE disk drives.

One of us must be missing something obvious. Let me explain again how I
think it should be working:

case A) need a huge space in a disk image:

1) dd if=/dev/zero of=disk_image bs=1M count=<size_I_need>

2) set the /path/to/disk_image in the [PARTITION0] and choose the
partition type it will appear under ($83 as linux ext2)

3) mke2fs - either in host OS or in ARAnyM OS. Please note the
flexibility - you can create the filesystem on host where it is faster
and then just mount the /dev/sda1 from linux-m68k inside. You can't do
that with disk emulation easily (atari_fdisk does NOT work with disk
images, AFAIK)


case B) I have an existing partition on the host and want to access it
from inside of linux

1) set the /path/to/disk_image and partition type in [PARTITION1] and
you can start accessing the /dev/sdb1 from ARAnyM's OS.

isn't this easy?
