Dear all, I need your help
I am trying to connect 3.5" FD to PCU50. OP SYSTEM: WIN NT4.x
when booting press F2 getting into SET-UP, old setting Floppy drive=disabled, I changed to enable(select 1.4M drive) and then F10( save and exit), I am sure I saved.
but after re booting I cannot found 3.5" FD in Windows nor in HMI "services" eg. I cannot use it.
when I check set-up setting again found "Floppy drive=disabled", that means setting went back to the old .(I am sure saved setting as I also changed "Booting Option from Floppy" and it kept)
what steps I missed.
