Normal Floppy Mode
Normal mode. Register 3F3 contains only bits 0 and 1. When this register is read, bits 2 - 7 are a
high impedance.

For this mode, DRATE0 and DRATE1 pins are
inputs, and these inputs are gated into bits 6
and 7 of the 3F3 register. These two bits are
not affected by a hard or soft reset.
BIT 7 MEDIA ID 1 READ ONLY (Pin 18) (See
Table 9)
BIT 6 MEDIA ID 0 READ ONLY (Pin 19) (See
Table 10)
BITS 5 and 4 Drive Type ID - These Bits reflect
two of the bits of configuration register 6.
Which two bits depends on the last drive
selected in the Digital Output Register (3F2).
(See Table 11)
BITS 3 and 2 Floppy Boot Drive - These bits
reflect the value of configuration register 7 bits
1, 0. Bit 3 = CR7 Bit DB1. Bit 2 = CR7 Bit DB0.
