i just realized from my own floppy Woes, with the 128k i am working on.

i am having the exact same issues as you are having right now.

Just realized there are ( 2 ) filters that control the internal and external floppy drive.

i have only been replacing the one.

i'm going to replace the other one in my 128k tonight i will let you know.

boots fine from external.

internal either : ejects / partially boots / makes funny noises for a bit then ejects / on a rare occurrence it will boot depending the amount of tries.
