Notes:
Drive Addressing and Interface Termination



RN1 Interface Terminator
  The Interface Terminator factory installed at RN1 provides proper
  termination for the interface lines. When daisy-chaining multiple
  drives, leave the terminator installed only in the last physical
  drive on the daisy chain cable; remove the terminator from each
  of the other drives. In most PC/AT installations, the C: drive
  is actually at the end of the cable and should retain the
  terminator.

DA1, DA2, DA3 Drive Select Jumpers
  The Drive Address jumpers are identified as DA1, DA2, and DA3.
  Address selection is binary, as shown in the table below. The
  ESDI controller's documentation will specify the drive address
  to use.

Drive
Address
DA3 DA2 DA1
1 out out in
2 out in out
3 in out out
4 in out out
5 in out in
6 in in out
7 in in in

 "Drive Address 0" (no jumper at DA1, DA2 or DA3) is a "deselect"
  (i.e., no drive selected). For many multiple drive installations,
  each drive must have a unique address. An exception is that for
  every drive in a PC/AT installation, verify that the only Drive
  Address jumper is at DA2; move the jumper if necessary (the
  special twisted interface cable that is generally used takes care
  of assigning a unique address to each drive). PC/AT controllers
  can typically support a maximum of two drives.

W5 Select the Spindle Control Option
  W5 selects the spindle control option. If W5 is installed, the
  drive waits for a Start Spindle command (after power is applied)
  to start the spindle motor. If W5 is not installed (the factory
  default configuration), the drive automatically starts the
  spindle motor at power-on. W5 is not installed for PC/AT
  installations.

W1 Selects the Sectoring Mode.
  If W1 is installed, the drive operates in the soft-sectored mode.
  If W1 is not installed (the factory default configuration), the
  drive operates in the hard-sector mode. W1 is not installed for 
  most PC/AT applications.

W2, W3, W4 Sector Size Option
  The number of bytes per sector may be specified using the Set
  Bytes Per Sector command or by selecting a default sector 
  configuration with jumpers W2, W3, and W4 as follows:

Jumpers   Bytes/Sector
W4 W3 W2 Sectors
Per Track
Formatted Unformatted
out out out 35 512 595

in out in 32 512 651

 * This is the default (factory installed) configuration and is
recommended for PC/AT applications
