I'm not sure about the High-Speed SCSI card, but I've done some poking 
around on my Rev. C and found that the 5380's registers are mapped to 
the first 8 bytes of the I/O space (C0F0-C0F7 for slot 7). I don't know 
how to set up a DMA (5380->card RAM or vice versa) transfer on either 
card (haven't gotten that far through the Rev. C ROM), but it looks like 
you could at least do dumb PIO transfers on it that way.
