We're running AOS 4.3 on an RT-6151 with an 'Extended ESDI' disk
controller.  When trying to format a Fujitsu 2263 disk using the
SAUTIL format utility we get failures (I/O error, Can't init drive).
The disk vendor suggested that the disk requires a 16Mb controller,
and that our controller is a 12Mb transver variety.  IBM controller
documentation is worthless; doesn't mention transfer rates.  We
assumed 'Extended ESDI' meant, among other things, the higher
transfer rate.  Any experiences out there with similar configurations?
The process of installing new disks is not new to us.  We previously
upgraded to a 110MB disk on this system with success.
