12.021 How is DMA set for SCSI cards with 8MB RAM cards on the GS?
DMA needs to be turned off with the Apple HS SCSI card or the RamFAST
revision C card. It does not need to be turned off with the RamFAST revision D
card (differentiated by being half sized). Current RamFAST cards are revision
D as are late model CV Tech cards. It is the RamFAST revision D that is
designed to DMA into any RAM card, even 8MB models. It was made around the time
of the CV RAM 8MB model that turned into the RAM GS Plus, but functions just as
well with the Sirius card.
