/dev/hda:

 Model=ST320423A, FwRev=3.02, SerialNo=7EJ1JLA5
 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
 RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4
 BuffType=unknown, BuffSize=512kB, MaxMultSect=32, MultSect=off
 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=40011300
 IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120}
 PIO modes: pio0 pio1 pio2 pio3 pio4 
 DMA modes: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4 



But having heard about various problems with VIAs, and particularly
pertaining to DMA.. and with this going wonky anyway.. I think I'll give
playing with other DMA modes, a miss :)
