Thanks in advance. I have two Conner IDE drives on my system (80MB and 100MB), and I have found that they work fine with SCO Xenix/V-386 (releases 2.1, 2.3), and Esix V/386 Rev.D. My 386 has AT-bus, and the only problem I ever had was when I increased the bus speed. I'm not sure if this was because of the `controller' or the drive electronics. BTW, does anyone have any information regarding the logical head/cylinder/sectors configuration of the various Conner IDE drives? Since I didn't get any docs with the drives, I had to use trial-and-error.
