VT82C586 e SouthBridge i dokolkoto mi e izvestno IDE controlera
vgraden v nego ne e UDMA66,a UDMA33.
Ako Chipset-a ti naistina e s VT82C586 niama nedejda da
go podkarash v nishto pove4e ot UDMA33.No i tova e dovolno mnogo. I naj
barzite UDMA66 diskove ne praviat po goliam 'pickov' vytreshen transfer
ot 33MB(uvi)
S programkata hdparam mojesh da si vklu4ish DMA2(toest 33) za
za dadeno ustroistwo.
No predi tova triabva da e vklu4en i DMA2 rejim na IDE chanel-a
na koito ti e zaka4en diska, i da niamash drugi ustroistva,koito,ne
rabotitat v DMA33 na syshia kanal(naprimer CD Teac) ;-)
Ili kato si kompilirash kernel-a si vklu4vash opciata
"Enable DMA by default if available"-ili podobna(ne sam siguren).No ne
ti prepora4vam.
Ili podavash na kernel pri boot opcia "ideX=dma" (X=0 ili 1)
Akoo diska ti master na IDE0:
na kernel-a "ide0=dma"
sled koeto s hdparm si vklu4vash DMA2 za samia disk:
/sbin/hdparm -c1d1X34u1A1W1 /dev/hda
DMA2 disk dava okolo 12MB testov fizi4eski transfer
mojesh da si testvash transfera s hdparm -tT /dev/hda
