(Pro/Auto/AutoPro)
If the controller that you are using is not listed in the DiskDupe menus then
it should be set as one of these types.
- Standard: supports high and low density regular speed drives and low density
double speed drives. Most primary controllers (for A: and B:) and inexpensive
secondary controllers are of this type.
- Enhanced 82077: provides additional support for 2.88MB drives and
double speed high density drives. These controllers normally use either the
NEC/Intel 82077 or the NS 8477 controller chips. The CompatiCard IV from
Micro Solutions, Inc., is an example of this type of controller.
SDS (simultaneous double sided) floppy drives require either two single
controller cards (like two CompatiCard IV's) or else a dual controller card
(like the Allegro I SDS controller) because data is written to and read from
both heads of the drive at the same time.
Typical controller configuration for SDS drives:
1st controller (for head 0 of the SDS drive):
Address: 370
DMA Channel: 2
Interrupt: 6
2nd controller (for head 1 of the SDS drive):
Address: 320
DMA Channel: 3
Interrupt: None (leave unjumpered)
