Floppy Drive Inop

This is intended to go in the desktop case in place of the old floppy drive.

I thought you said your mobo did not have a FloppyDriveController?

If you can enable the FDC, just put the LS-120 in place of the floppy, pinned as slave & in second position on the IDE cable.

EDIT: Sorry! Don't need an FDC when one uses an LS-120. It works on an IDE channel.

The standard floppy drive was left in the case when I rebuilt the computer. I changed the motherboard, power supply, CD RW, etc. The new motherboard had no floppy controller, so it just sits there.

Swap it out for an LS-120.
I'm fairly certain it'll work because it's on an IDE channel, and W7 has no problem with IDE drives.
It just reports in as a floppy.

Unless you have two peripherals already on your one IDE?

I pulled my LS-120 from my XP machine; pinned it master and hooked it up to the Primary IDE channel on one of my Windows 7 pc's (sata drive is boot h/d in here).

W7 installed it in about 2 seconds, and was reported in as floppy disk drive A:
Inserted three diskettes, and read them all.

Garf, it works and will give you a chance to use floppies at very fast speeds.

MANY FOLKS LIKE MY DAUGHTER!- has stored vital pics of my grand baby stored on floppies, and never bothered to get them converted. Now I have drug out a old XP Dell 9150. However, I disabled the floppy a long time back and I can't get it to work nor show up on Devise Manager or My Computer or PC Wizard! I am going to try the bios next after reading this!
I bet there are a lot of old floppies around that people would like to have!

Your instinct is correct. Probably on the first page in the BIOS you can enable the floppy drive. Also look for a setting for FDC - floppy drive controller, and enable that too.
