Strange but fast "bridgeboard" on Ebay

[Chain]

I got this

for free
it seems to be working with passive isa slots (im using ethernet card on pictures) so maybe ??

damn small linux works fine (P266, 64 MB ram)

Will it work in A2000?
I need to plug this card in one slot and 3com ethernet in second slot (and throw away A2088XT card)
I dont want to damage A2000 board so im asking first..
