Hi Alex,
I've been reading the SMC spec that the Linux-IrDA home page links to,
and I've written something that dumps the controller config to screen.
Could you please run it and send me your output? (smc-ircc-dump.cc)
I also made something that sets the DMA of the IR controller. I hope
that helps you with your floppy problem (smc-ircc-setdma.cc)
Both should compile with "g++ -o filename filename.cc"
Thanks,
Graeme
