OUI 00:30:56 'Beck IPC GmbH' (report if other!)

OUI vs Serial#

  • OUI 00:30:56 'Beck IPC GmbH'
  • MacAddr format: 00:30:56:fx:xx:xx, the xxx is (24 bit) serial number, written as 5 characters (hex).

Example: 

A:\>ver
...cut...
Target=SC12 Serialnumber=xxxxx
...cut...
A:\>

Interrupt 0xA0 service 0x00: Get serial number.
http://isa.umh.es/temas/micros/doc/sc12/doc/biosints.htm#0xA00x00
Interrupt 0xA0 service 0x17: Get MAC address of the Ethernet interface
http://isa.umh.es/temas/micros/doc/sc12/doc/biosints.htm#Interrupt_0xA0_function_0x17__Get_MAC_address_of_the_Ethernet_interface

Memory map says: 0400h - 04FFh for MAC Address. Possible to change MAC addr (plz check later)? I guess that 'on boot, the default mac == serial'. And that we could configure it via program at boot?

Note:

  • Pin17 @ SC12 = Link Led (connected to red led)

How to avoid periodic resets

  • Disable tcp2con.exe in autoexec.bat

It looks like tcp2con.exe performs a device reset after 120 sec.

Debugging

Hardware

"If it fails, the @CHIP prints the error message "RAM ERROR" on the COM port (using 19200 Baud and 8N1, regardless the entry in the CHIP.INI)." 

Source: http://isa.umh.es/temas/micros/doc/sc12/doc/bootfc.htm

Software

Use TRACE.EXE (seen in manual, link page here!) or maybe use the remote SYSLOG daemon ( http://www.lourensrozema.nl/ax/download/syslog_src.zip is ASM! untested..)
