Installed Plextor PX-716A into a basically new machine
as the only IDE device (I have an SATA hard drive).
The relevant parts of dmesg:

First question, why do I get this message? I don't have anything
on ide1.

I can't seem to enable DMA on this device:
| Code: | # hdparm /dev/hda
/dev/hda:

IO_support = 0 (default 16-bit)

# hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted

Finally, the device supports UDMA4, but it only comes up
with UDMA2 (with the BIOS set to Auto - if I set UDMA4
in the BIOS, the machine will not boot at all).
| Code: | # hdparm -i /dev/hda

Configuration:

Packet size: 12 bytes
Capabilities:
LBA, IORDY(can be disabled)
DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4
Cycle time: min=120ns recommended=120ns
PIO: pio0 pio1 pio2 pio3 pio4
Cycle time: no flow control=120ns IORDY flow control=120ns |
I do have an eighty pin cable on the drive.
Any ideas? Thank you in advance. |

curmudgeon,
You get
| Code: | ide1: I/O resource 0x170-0x177 not free.
ide1: ports already in use, skipping probe |
because your SATA is set up to look like ide1.
Here is the hint | Code: | | 15: 86048 0 IO-APIC-edge libata |
Its not an error.
You can't set DMA because the chipset driver for your IDE chip is missing from the kernel - it dosent know how.
Yourshows that the drive only supports up to udma2 and that its already in use, or would be, if you could turn DMA on.
After you fix your kernel, it will work at udma2 and thats as good as it gets for that drive.

I thought I had it there. The relevant part of my .config:
| Code: | #

Right now, I can't remember (or figure out again)
why I used that chipset. Should I add "Generic
PCI IDE Chipset Support?

I don't understand this then. From "man hdparm"
| Code: | -i Display the identification info that was obtained from the drive at boot time, if available. This is a feature of modern IDE drives, and may not be supported by older devices. The data returned may or may not be current, depending on activity since booting the system. However, the current multiple sector mode count is always shown. [...]
-I Request identification info directly from the drive, which is displayed in a new expanded format with considerably more detail than with the older -i flag. |
The -I gets information "directly from the drive" which
says it can do udma4. The manual also says it can do
udma4. Why does -i only say udma2?
Thank you again for your help. |
