edc* at mca? slot ?
ed* at edc? drive ?
The edc
driver supports IBM MCA ESDI disk controllers
and disks, most commonly found in IBM PS/2 machines. Supported boards include:
- IBM ESDI Fixed Disk Controller
-
- IBM Integrated ESDI Fixed Disk & Controller
-
This driver appeared in NetBSD 1.6.
The driver was written by Jaromir Dolecek
⟨jdolecek@NetBSD.org⟩.
The driver should also work properly on machines with more than 16MB of memory,
using buffer bouncing to overcome 24bit MCA DMA limitation.
