I have bought a High capacity floppy disk controller card from ebay.

I have searched for information on stason.org.. But i cant find nothing about this floppy drive card..

I have tested this card and the bios seems to be fine to me.. The logo pops up and thats all.. He said he cant boot from the floppy disk..

I want to have a little bit more information about those cards..
Some cards do have settings, others dont..

I already tried some different bioses on my other cards.. And it seems to my they dont work propally as they need to do..

I already backuped the bios in de case something will crashed here..

Could some regonize this floppy drive controller card?

Above on the left it having some jumpers like:

A / B / C / D / 8

What are those jumpers for? For make the drive letter and device active?
Or just what you want to set as Primairy drive??

And can someone tell me what that 8 is use for?

Is it right the C / D are ment to use 4 kind of floppy drives on this controller?

And on the upper right theres a block of 8 jumpers?
Is this used for setting it op to 360KB / 720KB / 1.44MB / 1.2MB

Is it possible to setup drive A: as 1.44MB and drive B: as 1.2MB drive??

~ At least it can do black and white~

iam also active on the vintage computer forum..

They helped me with this problem.. I only needed to test the card which settings it has.. I used Microsoft diagnostics tool to verify the correct drive type.. older diagnostic software only sees it as dual 360KB drives, also when you set it as 1.44M drive or 1.2M drive..

So i only had to set a jumper, see if it works / boots..
Then using a boot floppy with MSD tool..
And then check which drive type is set.. If it was the wrong setting. Putting the system off, and configure the jumpers again till it displays to right drives..

Older drives using more resistance, then ` newer` drives..

Now its correctly booting my 8088 NEC V20 from 1.44MB drive with active separate bios.. and can using my B: drive as 1.2MB

Iam very happy now, i only need to look for an working SCSI harddrive..

Tried to installing COMPAQ DOS 3.31 on it.. One time i could partition it and delete the partition.. After that it refusing everthing..

I think the HEAD of the drive is DOA.. It spins good, but it freezes my whole system..

If you enable one or two jumpers it uses that black resistor pack above the jumper. How more resistance is used then its configured as 360KB drive.. See the picture.. 1.44MB have both disabled on my card.. So wont using the resistor pack.. So thats how you can set the drives ID..
