Възможно ли е заради липсата на поддръжка за DMA да се получава ниска
скорост на записване? При мен гледане на видео с високо качество от
CDROM без DMA (PIO4 [1], теоретично 16Mbps = ~2MBytes/s, по мое
усмотрение ~4.8Mbps) е почти невъзможно. А гледането изисква доста
по-малки трансфери на данни отколкото записване при скорост 24 (да
кажем 2MBytes/s).

А как се държи като използваш ide-scsi емулация?
Поздрави,
