CDROM listed as "unknown" in BIOS but Windows detects correct name
I discovered an interesting problem. Maybe someone can help me figure it out. My Dell Optiplex GX520 Desktop running Windosws XP SP3 had a bad CDROM drive which I replaced with a dusted off Sony CD-RW/DVD-ROM. This is what happens when I played with the master/slave/cable-select jumper pin.
1. When master pin is jumpered: bios detects correct name of cdrom, windows doesn’t boot to desktop 2. When slave pin is jumpered: bios detects cdrom name as unknown, windows boots to desktop and detects correct name of cdrom 3. When cable-select pin is jumpered: bios detects correct name of cdrom, windows doesn’t boot to desktop 4. When no pin is jumpered: bios detects cdrom name as unknown, window boots to desktop and detects correct name of cdrom. The model of the cdrom is Sony CD-RW CRX320EE. |

Is the drive all by itself, or is there a second storage device on the ribbon cable ? IDE cables, you fill them from the end. If only one storage device is present, it goes on the end connector, not the middle one. The middle one is only filled, if the end spot is occupied. Other than that suggestion, I haven't a clue how the detections would be different, between BIOS and OS. Try the drive by itself on the cable, before giving up. Paul |

Correction. There are two SATA IDE controllers plus the one PATA IDE controller I've already mentioned. |

If the OS recognized the drive OK, I would not worry about how the bios sees it. The bios really only has to properly recognize the boot drive as the OS does not require a BIOS call for auxiliary drives. |

Just a strange thing to see the drive named "unknown" but Windows detects the right name. Oh well. |

Just a strange thing to see the drive named "unknown" but Windows detects the right name. Oh well. Whenever I troubleshoot, all I usually worry about is getting it going. No two machines have ever been the same and so many times, I experience something that makes no sense...but somehow works. If I was going to try and figure out the reason, I'd have a backlog of 100 machines on my repair bench. That said, I have seen my share of Dell Optiplexes that sure seemed to have problems with two devices on the same IDE cable. I don't recall seeing that issue anywhere else. |

CDROM listed as "unknown" in BIOS but Windows detects correct name
[snip]
Update. This seems to be a Windows XP SP3 problem after all. Though I haven't been able to pin point what area this problem exist in Windows. I confirmed it this way. I placed the jumper on the master pins of the CDROM drive. The proper cable connections were already made. Boot to BIOS to make sure the BIOS detected the drive. Then I booted the PC from a Fedora Linux USB stick. Confirmed that the CDROM was detected by the Linux XFCE desktop and even played some DVDs. But from Windows, the PC freezes while it is trying to load the desktop. So it's not the drive, the controller, the BIOS, the jumper, or the cable. Windows won't even boot to safe mode. |

CDROM listed as "unknown" in BIOS but Windows detects correct name

Installed the A11 version of the BIOS. But it didn't change anything. The Sony CDROM drive was still listed as "unknown". Some combination of Windows and the controller is jacked up. I have another old CDROM drive: Samsung SC-140b. It works in the PC but only in PIO mode. Windows initially detected it and set the primary controller mode Multi-Word DMA Mode 2. But once I put in a CD the PC locked up. I'm glad I have an external USB DVD drive. I give up on work with this old technology. Thank you everyone for your comments. Out! |
