 07711: ct486: Read 5.25" HD Floppy Disk in a 3.5" HD Floppy drive |
||||
| Description |
I have configured a 3.5"HD floppy drive on the [ct486] PC/AT 486 with CS4031 chipset (the bug also happens on another ibm5170's PC). And I can insert and read and 5.25" HD Floppy Disk on the 3.5" HD Floppy drive. It should not be possible. |

Which image is this? Is it happening with just one image or all images? Can you give command-line examples to duplicate your observed behaviors? |

It happens with any 5.25"HD floppy images. For example, take the "Dune (5.25)" [dune525] in the ibm5170 SoftwareList. Configure the A: floppy drive for a 3.5"HD floppy. Now you can insert the 5.25" disk image on the A: drive (at this point it should gave an error). Then you can access the disk with the command prompt "A:", you can make "DIR" command to list the disk files, and "CHKDSK" to analise the disk. |

For the CT486 machine you are using, is the internal BIOS selected to use the proper drive? Setting a device through MAME is only a layer of configuration as the BIOS that runs on the machine, I think, has the final say how that device is used. |

Yes I have the BIOS sets with the correct drive. If you see the middle screenshot, you can see that the A: drive is a 3.5" HD floppy drive. |

It seems to be happening in the Apple II Plus too. It gives me an error saying: "Device 5.25" single density floppy drive load (-floppydisk1 sabotage) failed: file not found |
