Since I'm running only SCSI hard drives and SCSI CD-ROM, don't need this support; Device manager - ! for the item, since Windows forces ongoing redetection, I basically ignore since not needed. Have disabled in BIOS/CMOS, modified settings in Control Panel, so no longer bugged by the find/driver load nag; tried various other routines but the annoyance remains. Although not creating any conflicts, don't like the ! or problem device alert. Here's the PROBLEM DEVICE per MSINFO32 detail.
Intel 82371AB/EB PCI Bus Master IDE Controller hdc

Could delete registry key, could ignore forever.
Don't bother with routine responses, know device manager codes and fixes, know normal tools and processes, but none serve me. IF IT ANNOYED YOU, WHAT WOULD YOU DO? PLEASE POST COMMENTS ON CREATIVE SOLUTION, BEST ONE WILL BE INVITED TO ANSWER.
