WinXP not detecting Chinon 5.25" FDD

A friend/retired Professor asked me to transpose his 5.25" floppy diskette
collection into MS Word or similar format.

Bought a Chinon - Model: FR-506 rev-b, SN#11195759, 5.25" FDD on eBay.

- Path: from mother board, ribbon cable to Chinon 5.25" FDD (17-pins, gap
after 2nd pin on left), to OEM 3.5" FDD last in path on ribbon cable. Tried
several ideas-
CMOS changed A:\ FD controller 3.5" 1.44MB to 5.25" 1.2MB, YES to Reset
Configuration Data (NVRAM), with and without 3.5" FD drive connected, dozens
of restarts.

Jumper Pins: used magnifying glass on circuit board. Reading
from left to right: FG, MS2, D-R, MS1, (sideways) IU, DS3, DS2, DS1, DS0,
TM.

Nine pairs of jumper pins. From left to right - jumpers are on pairs #2, 3,
7, 9.

The drive spins. I assume its getting power(?). WinXP still does
NOT detect it. Have old PC's handy, all 11-floppies DOS 6.2/Win 3.11 For
WG's (just in case).

I'm up for any ideas/suggestions?
Puzzled, Dave

Most new PC's/BIOS's don't support more than ONE floppy, be it a 3.5" or a
5.25"
So just connect ONLY the 5.25 as FD0 (DS0?)at the end of the cable, copy the
contents to your HD, convert the files to a suitable format, reconnect the
3.5" at the end of cable........

For drive select only DS1 should be jumpered.
 
Thank all of you for your suggestions. I did get it to work in WinXP.
Reversed the ribbon cable ends, pulled the OEM floppy drive out of the
picture, CMOS - instead of A:\ as 3.5" 1.44MB, set to 5.25" 1.2MB.
It reads the floppys. Problem now is his docs are in .WP format. I assume
thats an old version of Word Perfect(?). Once had Word Perfect for Win3.11
FW on 15-3.5" floppys but formatted them for other uses - kicking myself in
butt for doing that!
I have to either find an old WP version or an MS download that allows Office
XP in Word to read .WP files.
I'll came back later to read your suggestions. Thanks again, Dave
 
Thank you for the information. Saving all suggestions. Just about gave up
after hours of scouring the web and finding nothing. Really appreciate it,
Dave
 
You're welcome..

TM should be jumpered as it tells the computer if it is the only drive on the cable. Remove it if you have the older 286-386-486 computers etc. that the BIOS allows for more than one IDC drive. (if you want to have a 3.5 floppy to that is). One drive should have it I'm not sure if before after the twist on the cable.. My computer only allows for one IDC drive and the newer 1990's drives don't allow for pin settings. Factory come with the assumption only 1.44 MB floppy needed. Of course the latest computer BIOS doesn't even have a IDC connection so we have to get the USB floppy drive which is superfluous as who needs one unless you want to copy some old files or games. I find my computer is too fast for the games to play properly. Maybe I can shut down my multiple cores or limit the threads or something. Welcome to 2023 where everything junky is now collectable. I'm working on getting the PCI card that runs more than one IDC drive on a modern computer. Might not work on my Win10 64bit but might on my WinXP 32bit OS on another HD. If you want different OS with different bit values be careful. One can delete the other if you are not careful. They are designed to delete these files programed to see them as corrupt registry files.
The Photos shows TOSHIBA ND-0801AG or the UK version Chinon FZ-506 1.2 MB 5.25" Internal Floppy Drive. Owners manual says can read 1.6MB disks so no need for USB flash drives... LOL
