It sounds like whatever program you are using to write the boot floppy thinks
it is writing to a 1.2M disk (15 sectors/track, 80 tracks).  If you are
writing the boot disk from under MS-DOS, you need to examine the program
you are using to make it write to the floppy using 18 sectors/track
for a 1.44M disk.

I've received several reports from people using my modified bootblok.
The only problems people are having is when they write a 1.44M disk
without doing through a device special file for the floppy with the
minor device specified as 28.  Look in kernel/floppy.c for information
on the minor device numbers.
