   16-bit ISA are indeed common.  What is rare are 8-bit ISA cards with   
   on-board BIOS capable of running AT-class IDE drives.  Somewhat more common   
   are 8-bit ISA cards with on-board BIOS that only control XT-class IDE   
   drives.  XT and AT (perhaps more accurately called XTA and ATA) are not   
   compatible with one another.  Everything larger than about 40Mb is AT class   
   IDE.
