There isn't enough space and power inside an XT for two IBM hard disks and a floppy; IBM sells you a rather expensive expansion chassis to hold two hard disks. I suspect that a pair of low power half-heights or a half-height and the standard hard disk would work. It also turns out that the IBM controller card was designed to support other sizes of disks (5MB, 15MB, and 26MB, it appears from the BIOS listing) based on some switch settings on the card. But then they left the DIP switch off the card. If you carefully solder on the missing switch, you can plug in different sizes of disks. Amazing what must go in Boca. John Levine, ima!johnl PS: People who like real disks might consider the Maverick controller from Interphase, which can control two Fujitsu Eagle drives, giving you roughly a gigabyte of storage on your PC. Be the first on your block to have logical disks going all the way up to Z:.
