Exclamation IDE vs SATA?


Hi all,
I have a question for you hw guys.. I'm not able to have DMA working on my hard disk on a Acer laptop. This the output of lspci :

00:1f.2 IDE interface: Intel Corp. 82801FBM (ICH6M) SATA Controller (rev 04)

and an excerpt from .config :

ATA/ATAPI/MFM/RLL support (IDE) [Y/n/m/?] y
Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support (BLK_DEV_IDE) [Y/n/m/?] y
Intel PIIXn chipsets support (BLK_DEV_PIIX) [Y/n/m/?] y
Include IDE/ATA-2 DISK support (BLK_DEV_IDEDISK) [Y/n/m/?] y
...
Include IDE/ATAPI CDROM support (BLK_DEV_IDECD) [M/n/y/?] m
...

SCSI device support (SCSI) [Y/m/?] y
...
SCSI disk support (BLK_DEV_SD) [Y/n/m/?] y
...
SCSI CDROM support (BLK_DEV_SR) [M/n/y/?] m
...
* SCSI low-level drivers
Serial ATA (SATA) support (SCSI_SATA) [Y/n/?] y
...
Intel PIIX/ICH SATA support (SCSI_ATA_PIIX) [Y/n/m/?] y

but dmesg simply says that SATA port ha no device, so hard disk is created as /dev/hdc..
is this correct? I also tried to disable IDE/ATA support but the kernel isn't able to recognize the disk.
Thanks for your help in advance!!

What distro are you running? Many older distro's do not hav built in support for SATA drives in their native modes, and so they are run as regular IDE devices. You might also need to enable SATA enhanced mode in the bios of your computer.

I want to install Slackware 10.1, but also tried installation disk Ubuntu5.0.4, Fedora Core 3 and SLAX, Feather Linux, DSL, Dynebolic Live CDs and none recognizes the hard disk as SCSI disk..
It looks like:
ide0 doesn't support any devices,
ide1 has cdrom and hard disk connected,
sata controller has no device too..
quite strange.. why sharing the same ide port between cdrom and harddisk?
also BIOS doesn't show any menu regarding SATA or controllers

It sounds like ACER has set the SATA controller to compatability mode/IDE mode etc... The only thing that I can think of is to look for bios updates that will enable enhanced mode. Anyone else have ideas?
