mke2fs -O none -b 1024

The '-b 1024' is essential if you have a fairly large disk.

Somebody should really fix the ext2 code in MILO...

Well, the intent was that dbootstrap would just not give you the
option to make a non-compliant filesystem, and I kind of thought that
I had tested this code and made sure it did that.  But the code that
is supposed to do this looks fairly obviously wrong to me.  I'm not
sure if this is my fault or a case of boot-floppies developers who
don't know C very well messing it up where it worked before.

I'll try to get around to fixing it this week and I will put up a test
version for MILO users when I do so.
