Can it controll 1.44 MB drives too? .... According to my best evidence, I have what DTK calls a PII-151 (or maybe it's Pll-151) 3.5" Floppy Disk Controller, or Mini/Micro FDC. According to the manual, it will mix or match 5.25" drives of 360K or 1.2M, and 3.5" drives of 720K or 1.44M. It says there are jumpers to select logical drives A and B, and jumpers to select the on-board ROM BIOS for XT systems, and put it at any of three possible addresses, or leave it out for AT systems. There is also a jumper to tell it whether a hard disk is present. The manual says nothing about floppy drive requirements or setup. The packing list says the drive is Mitsumi 1.2M/FD "W"; that's all I know. I have no manual for the Mitsumi. If it matters, the mainboard is DTK with a DTK/ERSO BIOS and a V20 processor, running at 4.77 or 10 Mhz. As I said, I'm running the one floppy drive as A, and a Seagate 30M hard disk as C, and I'm happy as a clam with it. M. B.
