I need to install a 5.25 fd drive in a w 98 machine

May 13, 2012 at 04:18:35
Specs: Windows 98SE
I have two FD (A and B) on my Win98SE comp. I rec. message:. Device not ready. Perhaps the BIOS parameters are incorrect, but how should they be set? one FD is a 144 Mb unit (A). the other is an older type Matsushita FMD01650B4 (Perhaps FMDO165OB4) O or 0 cannot tell 360kb (B) type or maybe larger. This older device has 3 jumpers, the first marked DS1 2 3 4, the second marked DA or UA (possibly OA) the third jumper is marked RY. It can be present or omitted..

Hi Larry,

Did the floppy drives ever work in this pc?

would not expect you should need to touch the jumpers on floppy drives.

a) have you set the floppy drives correctly in the bios?
advise back the options if they are not clear - possibly:-
A: 1.44 for 3.5" B: 1.2 for 5.25"

b) have you connected the interface cable correctly?
would expect it to have 5 connectors:-
1 - mobo
2 - drive A: (1 - 3.5" 1 - 5.25")
2 - drive B: (1 - 3.5" 1 - 5.25")

This may help:-

Please advise back on progress.

Good Luck - Keep us posted.

Sounds like some type of combination floppy drive, not a straight 5.25" The most common type of 5.25 is the 1.2Mb. There were also 720Kb models, or models that could read both types.

Also, the 5.25" was usually setup as the A drive with a 3.5" as the B drive.

Hi OtheHill,

If it is a combination drive, I think you cannot have another floppy drive unit installed, as the combination one acts as both A: and B:.

With the combination drives I have used, the strap setting(s) gave the option to decide whether the 5.25" or 3.5" were to be drive A: and the 'other' would then become B:.

Good luck - Keep us posted.
