P100, w95, upgraded sound card to SB and added a PCI Diamond Supra modem. All went well and everything worked. Then a day later, getting an A: drive error msg at boot. Device manager shows A:drive conflict (red X) and disabled but no conflict listed, CDROM (red X), drivers missing from Hard Disk and no access to A: to load new drivers. Also an IDE Controller (red X) problem. All together and all of a sudden. Can't load anything with no CD or Floppy access! The BIOS shows everything normal. Any suggestions as to where to go from here? Thanks.
