How to interface RTL8019 with 386EX without ISA or PCI bus

Hi all,

I have a problem to interface RTL8019as with 386EX, there is not ISA
or PCI bus on the board, how can I connect NIC to the CPU directly.
For the read/write Timing Characteristics of the RTL8019AS, what must
I do to make them match each other. How to consider these signals of
RTL8019as: IORB, IOWB, SMEMRB, SMEMWB, IOCHRDY, AEN.

Any reply is greatly appreciated.
