The upper two addresses of the PROM store contain
bytes that identify whether the MX98905 Controller is
in 8- or 16-bit mode. For 16-bit mode the values of
these bytes are 57H; for 8-bit mode they both contain
42H. Software driver can read these two bytes to
determine whether the Controller is in 8- or 16-bit
mode.
5. 8-BIT I/O PORT COMPATIBLE MODE
In 8-bit I/O port compatible mode, the I/O mapping is
the same as in 16-bit mode. The memory map for 8-bit
I/O port compatible mode is shown below:

6. I/O PORT NON-COMPATIBLE MODE
Although this mode is similar to Novell's NE2000, it
also allows the user to use the full 64 kbytes of address
space except for an initial page for the PROM. I/O map
is the same as compatible mode. Memory map is
shown below:

Although the PROM occupies 256 bytes, it is only 16
bytes long. There is a partial decode inside the
MX98905 so the PROM is mirrored at 16 addresses in
this region.
7. POWER-ON RESET OPERATION
When the duration of RESET signal is longer than
400ns, the MX98905 will read configurations from
EEPROM depending on the value shown on
EECONFIG pin. User should prepare all the data the
MX98905 needs in the EEPROM before switching on
the PC. The following table shows the format of
EEPROM:
