sorry , before I got this problem, the board has been sent out to my friend.
and I didn't save the output message. sorry!

I just replace with ATMEGA128-16AU, and then, it work properly.

Basemon and testrtl all try with both type MEGA128, even MEGA128L on
7.3728M. only ATMGA128-16AU work.
I will test it again in a few days.

btw, I order  5 PCB from a  manufacturer. and I have only one. but it has
big problem, and I am tring resolve it.
it use ATMEGA128-16AU.
Tera term's output below:

BaseMon 4.2.0
Compiled by AVRGCC for ATmega128
Baudrate select = 23
External RAM Test... 28416 bytes
Banked RAM Test...   none
Serial FLASH...      0 bytes
Detecting NIC...     RTL8019AS
Testing NIC...       OK
I/O Port Test...     OK

Press any of the following keys:
    B - Send broadcasts
    E - Ethernet controller read/write
    J - Jump to bootloader
    S - SRAM read/write
    X - Exit BaseMon, configure network and start WebServer

you can see, all is ok. I can send broadcasts, but when I choice X, and
after I setup the network, the webserver can't start.
I want to know, what output can give when I do SRAM read/write test?

I also burn other example such as httpd, it can not output any message on
Tera term.
