my 2 GOTEK no longer work after Flashing with FF

[DoYouTech]

Hello,

I am having trouble with 2 Gotek 415, 3x7 segment screen + 2 buttons.
I am using them both on old computer like ASUS P2B-F etc for DOS, 3.11, w98, etc
They were working perfectly with the USB floppy manager 1.4 software out of the box with all 1.44Mo I could get or create myself with ultra ISO then use the manager software to put on USB sticks.
I just wanted to "upgrade" to larger IMG, IMA files like 2.88MB or more up to 120MB (LS-120) or 250MB (ZIP) which I still use phisicaly with those devices to boot and install software faster than 1.44MB regular floppy.
So I folowed the "how to FF" for initial flash, solder a 2 pin header on both goteK then use an USB A-A cable to connect to PC and use flashing tool
All that went smooth and successfully flashed with FF 3.43.
I didnt moved the jumper at the back and tried imediatly one of the Gotek but I can select IMG / IMA files, screen show up numbers 000 to 0xx, I get error selecting large 120MB files so I removed them from USB Sticks. but after that I can not boot from selected IMG nor read it.
when I type "dir a: " I see the red light flashing on Gotek but PC almost imediatly answer "Not ready reading drive A Abort, Retry, Fail? "
I tried adding FF folder, adding FF.CFG alone in USB stick root or in FF
I tried setup FF.CFG into IBM PC or PC-DOS or unspecified but nothing works
always get the same message on my P2B-F, or other motherboard, I even tried to setup Motherboard in 1.44MB instead 2.88MB and read only 1.44MB IMG / IMA files but nothing works still the same.
When I move the Jumper to JC instead of S1/S0 (A: or B:) the green light stop turning on and PC is much slower to give me the same message error.

I also tried to flash one GOTEK with the FF_Gotek-bootloader-3.44.upd or flashfloppy-bootloader-3.44.upd then corresponding FF_Gotek-3.44.upd or flashfloppy-3.44.upd.
but still the same.

I am handicaped and have very bad eyes so reading all discussion here took me almost a week and not I am not finished.
I hope someone can help me fix that soon or help me go back to old GOTEK original system.

Best regards.

I also tried similar test with 3.44 when I saw it out but still same.

Have you added a jumper to position JC at the rear of the Gotek. That is in addition to the jumper at position S1. This is necessary for correct operation with an IBM PC compatible.

Hello sir,
indeed it's working now. thank you so much ! :)
That's where I got confused because, I might have read this wrong, but I was under the impression we had to move the jumper to JC not add one.
And am I wrong too to think the FF.CFG was supporsed to overide the jumper setting ?
Anyway thank you so much again for the help !

I tried my IMA and IMG files up to 2.88MB are working but it stoped here.
I tried an empty 3.84MB also build with UltraISO but I still get the E31 when selecting this image or my LS-120 120MB floppy image.

Best Regards.

FF.CFG can override the JC jumper setting. The S0/S1 jumper is always required, as that is a physical drive select line and without that jumper, your drive will never be selected!

2.88MB is possibly your limit, unless you know the expected "geometry" for a 3.84MB image.

Ah ok I understand now about the jumper.
Maybe there is still a bug as I used the jumper in S0/S1 without jumper in JC and FF.CFG specified for PC-DOS but it still gave me the error "not ready..."

As for the geometry for other IMA format I only have the tool to create them but no idea about the CHS info.
Previous picture was truncated so I'm posting a new one here.

As you can see on the left side I found the geometry for LS-120/240 on this interesting website :
https://www.deathwombat.com/diskgeometry.html
But no geometry info on other type of files.

Do you think it would be possible to add the LS-120/240 format to FF on our Gotek?

Best Regards.

A floppy drive has only two heads. So this is impossible to support.

The need for jumper JC is because it changes some drive-ready signalling, hence you get Not Ready errors without it on a PC.

maybe I should start a new threads as this problem is solved?

[keirf]

I think all your questions are now addressed.

[DoYouTech]

indeed.
A bit sad that those gotek can not do what CD/DVD do about the 120MB boot file.
I was hopping to get more than 2.88MB for a boot file.

anyway thank you for you time :)
I am very happy those gotek work again ;)

Best Regards.
