Using Intel ICH5 IDE+SATA Under 2.6.15-rc6 - Cannot find DVD-RW?

Using Intel ICH5 IDE+SATA Under 2.6.15-rc6 - Cannot find DVD-RW?

[Justin Piszcz]

The BIOS see's my drive without any issues.

My config: [AUTO, allow for up to 6 devices on IDE/SATA total]

p34:~# cat /dev/hdc
cat: /dev/hdc: No such device or address
p34:~# cat /dev/sdc
cat: /dev/sdc: No such device or address
p34:~#

p34:~# dmesg | grep NEC
p34:~#

CONFIG =

SATA1 -> RAPTOR
SATA2 -> SEAGATE
IDE0 -> NOTHING
IDE1 -> MASTER (DVDRW/CDRW)

But for some reason the kernel is not seeing it?

This is the same problem I am having (no OOPS but I cannot see the DVD 
drive either)--

DVD drive not recognized

The ata_piix SATA driver grabs ownership over the IDE ports when it is 
loaded, but (by default) does not support PATA ATAPI devices such as the 
Ultrabay optical drives. Thus, if the ide driver is compiled as a module 
and loaded after ata_piix, the DVD drive will not be recognized by either 
driver.

Either of the following configurations will work:

     * For kernel 2.6.14 and newer: enable ATAPI support in the SATA system 
using libata.atapi_enabled=1 (see below; this is experimental).
     * Compile IDE into the kernel (non-module).
     * Compile both IDE and SATA as modules and make sure IDE is loaded 
first (the module is called 'ide_generic').

Note that the optical drive must be in the Ultrabay during system boot 
(Ultrabay device swapping is currently unsupported).

SUMMARY:

The libata=1 option is if you use "AUTO" in the bios, then it sees it but 
you can't (or I couldn't do anything with it anyway)

scsi1 : ata_piix
   Vendor: _NEC      Model: DVD_RW ND-3520A   Rev: 1.04
   Type:   CD-ROM                             ANSI SCSI revision: 05

I googled around and then found setting it to Enhanced Mode worked!
It sees all the devices properly now.

hdc: _NEC DVD_RW ND-3520A, ATAPI CD/DVD-ROM drive
ide1 at 0x170-0x177,0x376 on irq 15

If you want to get decent throughput from your DVD drive, you may also 
want my combined_mode= patch.  Boot with combined_mode=libata and 
libata.atapi=1 and I think you'll get good behavoir.  Last I checked 
the patch was sitting in one of Jeff's libata trees.
