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. thanks

Good luck Nit ================== Hi, Nit I checked MMC.ini, the setting "FloppyDisk= a:". But still I can't activaed floppy drive. I think the problem is not HMI software but PCU50 HW or BIOS setting.It is nothing to do with Windows NT4.x or Win.XP. I tried both Op system PCU50. The problem is when booting starts, I press F2 getting into set-up, I can change time and date and save. but when I change Floppy Drive from "disable" to 1.4MB(3.5") and change Floppy contrller to "Enable" , then F10（save&exit) then are not keeping my setting after re-boot. =they went back to "Disabled". I not know there is any jumps on the PCU50 borad to make that enable. please help me。

SteveA Posts: 297 Rating: (41)	Are you trying to use a new style USB floppy with an old PCU50 running NT4? I think the old PCU50 can only support floppies with a ribbon cable connection to the PCU50. HTH, SteveA
