I'm trying to build a DVD duplication box with ATAPI DVD burners and a
HighPoint Rocket-100 controller card. For some reason, this combination
will not allow DMA transfers to the DVD drives, limiting write (and
read) speed to about 1X, even though the drives are capable of 16X
writing.
OS: Linux v2.6.21/i386 with module hpt366 loaded
# hdparm -d1 /dev/hde
/dev/hde:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Input/output error
using_dma = 0 (off)
# hdparm -I /dev/hde
/dev/hde:
ATAPI CD-ROM, with removable media
Model Number: TSSTcorpCD/DVDW SH-S182F
Serial Number:
Firmware Revision: SB01
Standards:
Likely used CD-ROM ATAPI-1
Configuration:
DRQ response: 50us.
Packet size: 12 bytes
Capabilities:
LBA, IORDY(can be disabled)
DMA: mdma0 mdma1 *mdma2 udma0 udma1 udma2
Cycle time: min=120ns recommended=120ns
PIO: pio0 pio1 pio2 pio3 pio4
Cycle time: no flow control=227ns IORDY flow control=120ns
Commands/features:
Enabled Supported:
HW reset results:
CBLID- below Vih
Device num = 0
boot messages:

(The HighPoint BIOS menu fails to detect any drives, so there doesn't
seem to be any way to change this BIOS PIO setting.)
Any suggestions? (Please copy responses to me, as I'm not subscribed to
