CD/dvd drive not found
Dell Dimension B110, running XP, SP3
CD/dvd not working and computer cannot find the drive - BUT - only if computer is booted up with the broadband internet cable attached and it takes forever to boot up, probably because the computer is trying to find the drive. Once the computer is fully booted up (without the CD/dvd drive function) the internet connection works fine. However, if computer is booted up without the internet cable attached, it boots up quickly and everything works fine - including the CD/dvd drive. So - we can either have the CD/dvd RW drive OR the Internet connection, but not both. Don't know if this has anything to do with it, but this is my son's computer and he had not opened up the case and blew the dust out since he bought it, so when I opened it up, I found a "blanket" of dust over the air intake and dust balls the size of golf balls rolling around inside the case. |

For the network, check the line on the following web page called "On w/ PXE". PXE is network booting capability, and for a home computer that typically would not be used (it is to allow booting a computer from a server somewhere on the network). The BIOS default for the network interface cotnroller is "On", so someone would have had to modify it, to enable PXE. It could be the computer is attempting to use PXE to boot the computer, and in the process, is sending packets out via the broadband connection. When the network cable is disconnected, the BIOS can sense there is no connection, so it stops trying on that interface. That is all I can suggest for your behavior with respect to the network cable. http://support.dell.com/support/edoc....htm#wp1054626 For the CDROM, the drive could be a ribbon cable type, and sharing a cable with a second hard drive or optical drive. Sometimes, one drive can upset another drive on the cable. The Dell may have the drives all jumpered "cable select" or CS. That is so they don't have to be individually jumpered "master" or "slave" when sharing a cable. Test the CDROM by itself on the ribbon cable. Use the end connector, like this. You can leave it jumpered "CS" as Dell shipped it. Mobo_end --------------X------X | | CDROM If it still isn't working, check the power is plugged firmly into the CDROM drive. It could also be a problem with the ribbon cable itself, although that would be more likely if the owner of the machine had been playing with it, tugged on it, and so on. So knowing what's been done inside the machine recently, may suggest whether there is a reason to try swapping it out. The thing is, as far as I know, optical drives should respond, even if the drive mechanism itself is damaged. I don't think they cease to respond to the OS, if there are minor issues. It is only when media is placed in the tray, and the drive tries to detect it, that you discover the real health of the optical drive. So I don't see how the drive can withhold service, unless somehow it thinks media is present, and is actively pretending to be doing reads on it. A hard drive is different. Any little glitch that affects the ability of the drive to finish its self test or startup procedures (reading stuff from below sector 0), results in the drive refusing to respond to the host. A hard drive is more likely to hold the host hostage, and is more consistent with your description. The optical drive, on the other hand, should play nice, until you put a disc in the tray. When ribbon cable devices share a cable, it is possible for the controller board on the drive to fail, and hold up the shared bus on the cable. And that is the reason for testing drives individually, to see if the symptoms change. The problem might only show when two drives are sharing the cable. Paul |

CD/dvd drive not found
I'm afraid I got in a hurry and forgot to add this piece of information:
When I attempt to boot up with the internet connection in place, it brings up the bios screen with this message: "Secondary drive 0 not found. Strike F1 key to continue. Strike F2 to run the set up utility. I selected the F1 option. I did not feel qualified to run the Set up Utility. Maybe that's the problem.

I think this is a picture of your computer. It looks like it has room for one optical drive and one hard drive. http://support.dell.com/support/edoc....htm#wp1043338 I think you can temporarily work around your issue, by using the BIOS setup. That is what it is there for. The first thing to learn, is how to "escape" from the BIOS without making any changes. There should be a "discard changes and exit" option, in the Exit section of the BIOS setup. Unfortunately, the Dell BIOS setup page, doesn't give any details. If you're successful in making changes, you'd use the "save and exit" option, so that the changes would survive turning off the computer later. The changes wouldn't be kept for later, unless you save them. One change you can try in the BIOS, is change the boot order. Take a look at the boot order, and see if the hard drive is "ahead" of the CDROM. Perhaps if it is, the BIOS will stop looking for the CDROM and making a nuisance of itself. # Floppy device # Hard-Disk Drive # IDE (CD-ROM) The other option to try, is set the network interface to "On" instead of "On w/ PXE". I can see a potential for interaction between the CDROM and the network interface, but it is a pretty far fetched theory. Normally, based on your symptoms, I'd be changing the CDROM drive. Or even disconnecting the data cable from the CDROM for one boot cycle, to look for any change in symptoms. But the fact that the CDROM is detected when the network is disconnected, is pretty strange. I'm hoping if there is an issue with not enough low memory for BIOS add-on modules, that disabling PXE will stop it. The PXE boot module is an add-on, and I would have expected a tiny memory footprint for it. Normally, it would take a lot of added hardware (like plugging in three PCI SCSI cards), before the low memory to hold BIOS add-in module allocations is full. The space allocated is 128KB from down in the 640KB area. The 128KB is available "first come first serve", so any BIOS module late to the party gets left behind. Other than that, there shouldn't really be an interaction between those subsystems, even if one of the subsystems is broken. The only fight I know of, is over the 128KB temporary area, and that normally takes a lot of added hardware before it happens. So far, you haven't presented any evidence the computer is chock full of added stuff. Paul |

CD/dvd drive not found
I am normally a fearless adventurer when it comes to delving into computers
or any other electrical or mechanical device - but - only when I have some remote idea of what I am doing. In other words - I recognize my limitations. And I must tell you that I am totally terrified of getting into that Setup utility. Never been there. Never done that. But since there is an "Exit" without save option, I guess I can give it a try. Wish me luck!
