At least with original IBM equipment that is. I've had a system working with 4 of the IBM XT controllers (made by Xebec) each controlling 2 drives. C: D: E: F: G: H: I: J: all at once under DOS 3.3 in a standard IBM XT with expansion unit. Was a blast having 8 drive LEDs ! It's a matter of playing with jumpers on the card to disable the ROM on all but one of them, and to set the other cards to different IO addresses. If people are seriously interested, mail me and I'll dig out the information, and I'll summarize the info if the volume warrants. -- Dean Carpenter ...cs.utexas.edu!bunyip!deano (preferred) ...cs.utexas.edu:ibmchs!auschs!ausvm1.vnet.ibm.com!deano (sometimes sporadic)
