Hello- I need a bit of advice on installing a 1.2 Meg drive on my XT. I have a 360k drive now and I want to put in a 1.2 Meg as drive A, with the 360k as drive B. My floppy controller is on the same card as the clock/calendar, the serial port and etc (i.e. the hard disk controller is separate from the floppy disk controller.) There is a cable connected to the back of the floppy disk controller. The cable has two adapters on it. One of the adapters has a twist in the wire, the other one doesn't. (I think the one with the twist is for drive A). I connected the adapter with the twisted wires to the 1.2 meg and the other adapter to the 360k. The problem is that I get a general failure when I try to read from the 1.2 Meg (drive A). If I try to get a directory from the 360k (drive B), it tries to read from the 1.2 Meg. The light never goes on on the 360k drive. I hope this explanation is clear. Thanks in advance for your help. -Chuck Wooters wooters@icsi.berkeley.edu

Unless your PC's BIOS supports 1.2M floppies you'll need to get a
new floppy controller which has a ROM on board which provides the
support for the 1.2M drive.
In addition, you have to make sure that you've got the floppy
drives configured correctly so that they aren't clashing and that
the termination resistor pack is only installed on drive B.
Hope this helps

The regular controllers won't handle 1.2Mb. There is a article in Byte March '89 about doing this. *=================================================* * Douglas Myhre <doug@loihi.hig.hawaii.edu> * * Hawaii Institute of Geophysics * * Research Computing Facility * * 2525 Correa Rd. * * Honolulu, HI 96822 (808) 948-8713 * *=================================================*

Also, some early versions of DOS have problems with some drive types, and you may need to install a device driver. In the rare case that original ideas Kenneth J.
