I have a Compaq model 5835 w/celeron processor running Win98. The hard drive crashed, something came loose inside the drive. I replaced the drive with a good one from another computer, with Windows ME o/s. When I boot the computer, I get the 1782 Disk Controller Failure message, and I'm given two options. F1 to boot computer, or F10 to enter setup. Either option works. F10 enters setup mode, where I have reset the default values, and F1 boots the computer, after which everything works fine. The only hang up is at boot. I can't seem to get rid of the error message and the F1 and F10 options. I have moved the jumper to reset the bios on the MB, but I still get the same error message. Device manager says the primary and secondary hard disk controllers are working properly. When I boot, using the F1 option, the hard disk spins up, loads the o/s and all is well. If the disk controller was bad, would it still do this? Is there a way to reset or somehow get rid of the error message so the computer would boot without going through the F1 option? If the disk controller has failed, can I install an IDE controller card in a PCI slot and bypass the onboard controller? Any suggestions are welcome. Thanks for your help!
