| 294552 | 2004-11-21 06:37:00 | Hi, I have just installed a 5 1/4" floppy disk drive in my computer because I love old school gaming. unfortunately, when i installed it i set the BIOS settings of my computer to recognise both A: and B: but my Windows 98 (not SE) won't recognise whichever drive i set to B:! ?:| should 98 recognise both!? any help appreciated. |

| 294553 | 2004-11-21 06:50:00 | If the BIOS has 5 1/4 for B, change it to 5 1/4 in the BIOS. Most BIOS'es these days, I would say use 3 1/2 as A and B. | Spacemannz (808) | ||
| 294554 | 2004-11-21 07:18:00 | I doubt if you will get a modern bios to recognise it. Jack |

| 294556 | 2004-11-21 12:26:00 | The ribbon cable has a twist in it, right at the end? If not, this could be the problem as the twist was to determine the primary and slave of the device. You can't have both drives connected to the top connectors or middle connectors, they have to be seperated and that twist must exist between them. Some 5-1/4" drives had jumper selectors like that of hard drives to determine it's existance, position, check for those and alter them, you may need to go through trial and error. Kame |

| 294557 | 2004-11-21 19:17:00 | well yes there is a twist between the 2 drives on the ribbon so i dont think its that. but theres an awful lot of jumpers on the 5 1/4" drive that dont appear to have any significant markings. thanks |

| 294559 | 2004-11-22 02:56:00 | If the BIOS is seeing both you should be OK . But it's not working . . . ;-) The BIOS might be just taking your word for it . :D Check that there is a jumper on the DS1 position on the 5¼" . (If there is no DS0, use DS2) . The twisted section of the cable flips the select and motor control bits . 5¼" drives (and 8") had jumpers so they could be selected by software . The jumper positions will be marked DS0 to DS3, or DS1 to DS4 . Yes, four . :O If you had a lot of data (and could afford it) you could use four drives . (I've got an interface somewhere for 4 floppies) . The DS0 and DS1 starting number is the old "out by one" problem . With an untwisted cable, you set one drive to 0 and the other to 1 (or 1 and 2) . To save assembly time, someone thought of twisting the few wires in the cable, and have all drives jumpered to 1 (or 2) in the drive factory . Drive 0 (A) is "1 flipped" (at the end of the cable) and drive 1 (B) is "1 not-flipped" . I haven't seen jumpers on 3½" drives, so they are probably hardwired as "1" . |

| 294561 | 2004-11-22 04:08:00 | well have tried all combinations using the DS jumpers and cables but to no avail. Windows 98 only shows whichever drive i set to A: and doesnt show B: more help? |
