I'm trying to put a 1.44 meg floppy drive into a 1000SX. I am running DOS 3.3, so the device driver is not a problem. Also, I purchased a 2-drive controller card to drive the floppies (I'm leaving one of the orginal 360K drives in). After some fiddling, I got both drives in (damn short power leads...). I put both drives on the new controller card (I completely removed the cable from the built-in controller). Both drives are jumpered as being drive 1, beacause (at least according to the PC repair book I have), if the controller cable has the twist built in, both drives should be drive 1. I could not find a terminating resistor on the new 1.44M drive. For info, the 360K drive is a Teac, and the 1.44M is a Mitsumi. Anyways, after getting everything in and set up, I powered up and tested the system. Neither drive worked. On power up, it hit both drives as usual, but if I tried to change to either the A: or B: drive. it spun the drive for a while, then spit back a "Not ready reading drive...." error. After looking thru the 1000SX technical reference, I found that I could disable the floppy disk controller interrupt with a switch on the motherboard. I tried this, but it seemed to have no discernable effect. Now, down to the question. Does anyone have any ideas/suggestions or vague clues? Any experience with this sort of thing out there? Any help at all would be greatly appreciated...
