hi,

Greg, thanks for Your tips. Here my other doubts...

I was looking already for this manual, but I haven't found it...could
somebody tell me, where can I find it? Or perhaps could someone mail me this
file?

but theoretical this could be working with my board, I need only to modify
some adresses and register values?
I have a SanDisk PCMCIA flashdisk and perhaps (I don't have it yet) a ne2000
compatible network card. In this case I don't need a PCMCIA socket service?

I understand, this is a second possibility. I have to hack PCMCIA enabler or
Jesper Skov's driver...I don't know which way is the most simple one...with
Jesper's solution I get probably more general stuff, but need to solve this
problem as quick as possible.

  are they general? they should work, if I get working hd64462?

 PCMCIA driver with hd6446x support? So for SHx and HD6446x we have
companion chip support integrated with PCMCIA driver? These are modules, and
in arch/sh/kernel/setup_hd6446x.c are defined these early CF enable for
HP690?

If I use ne2000, there should be no neeed to hack it, theoretical.
