This was posted several days ago but I haven't seen any replies. Can anyone help? Can anyone explain what the Secondary IDE Controller does ? About 6 months ago I did a reinstall of Win95a and noticed under Device Manager/Hard Disk Controllers that this device was listed as causing a conflict. I disabled the device with the intention of looking into it after I returned from a business trip. I completely forgot about it and the system has been running fine without it. I recently ordered a Beta copy of Win98 and expect when I install it this device will be shown as causing a conflict. If it does should I disable it again or try to resolve the conflict ? My Device Manager/Hard Disk Controllers presently shows the following: Primary IDE Controller (Single FIFO) Standard Dual PCI IDE Controller Standard IDE/ESDI Hard Disk Controller Looking forward to your input.
