Two questions about ST hardware:

1) Does anyone know something about the SH204 HOST ADAPTER CARD bug ?
      (HAC always returned SCSI success status even if the SCSI
       controller (ADAPTEC 4000) signals an error)

2) Does anyone know, how far the DMA chip can address in memory ?
      e.g. forcing a FWRITE(...) from address $FC0000 (the ROM location)
      with more than 511 bytes produces garbage contents in the written
      file,
      same done with address $FC0000-1 correct contents.
      (assumed, the system copies first the ROM data into RAM space
       (because odd address) and then to the disk as the AHDI driver
       do it )
