[vortex] Problem with 3com 10/100 Mini PCI adapter(3c556B?)under 2.2.19

Dear Yamamoto-san and Andrew (and everybody),

I just remembered something that might be useful:

http://www2.neweb.ne.jp/wd/fbm/3c556/installation.html
[...in case of problems] turn off Plug and Play (PnP) in the BIOS
completely (turning off the PCI Plug and Play only is not enough). On
the [Daewoo] Qrium [PC] it is not possible to turn off PnP in the
BIOS, so reset the ECSD (configuration data), and unplug the power
supply.

Do you have something that looks like ECSD (Extended System
Configuration Data) in your BIOS? Is there an option to reset it?
(Don't forget to unplug the power supply).

Also, I couldn't find in -Ra support for the EEPROM_OFFSET (that 0x30
offset found only in the 3c556B; did you see it in -Re? BTW, where did
you find -Re?).

Translation :-): Yamamoto-san, if you try Donald's drivers and it
doesn't see the Ethernet address of the 3c556B, that's the reason...
It might be worth trying 2.4 first.
