But in fact something working wrong :). As I wrote exchange
cyrix cpu on intel or isa ne2000 on amd pci has solved all my problems.
In a few days I will be able to test pci ne2000. If it will working
fine with cyrix, then the problem is isa delays. Are you agree? Should
I test other isa cards like 3com?

irq is free.
