Just to clarify, Michael and I did reach a solution (i.e. don't attempt
2-byte DMA transfers) after we kicked around various theories for years,
and tested some of them with Stan's help, and fixed some mac_esp and
esp_scsi bugs along the way. But someone still has to write the code for
zorro_esp. The code is easily adapted from mac_esp, now that mac_esp works
properly, since you only have to implement the the transfer_size <
FIFO_SIZE case or even just the write != 0 case. I can help with this
patch if need be.
