- Can anyone clearly state what exactly the DMA transfer speed on the
- 1542B actually specifies? Computer memory to card? If so, isn't this
- somehow constrained by your bus speed or controlled by the DMA on
- the motherboard...??? One of the other postings implied is was the
- data transfer rate on the SCSI bus while another implied it had to do
- with the computer/adaptor interface?
