Teac-a ne poddyrja DMA.
Kakto kazah v edno predishno pismo 2.2.x ne podyrja DMA i PIO na
edin i sysht kanal. Ta moje i da imash problemi s CD-to vyrzano zaedno
sys disk-a na IDE0.
Zashto ne si zaka4ish dvata diska na IDE0 i CD-to na IDE1 sami4ko.
Ili CD-to s tozi disk koito ti e "po-malowajen" s izklu4en DMA.
