[PATCH] PATA support for Intel ICH7 (intel 945G chipset) - 2.6.14.2

[PATCH] PATA support for Intel ICH7 (intel 945G chipset) - 2.6.14.2

[Jan Panoch]

Hi,

This patch adds additional Intel ICH7 DID's for Intel chipset 945G to
the piix driver.
I need to add PATA support for new intel 945G chipset on Asus
motherboard P5LD2-VM.
If acceptable, please apply.

Thanks,

Jan

PCI_DEVICE_ID_INTEL_ICH7_2 has been removed in 2.6.15 as it was unused.
Your patch is whitespace damaged (mailer ate the tabs?). You also need to send 
it to the linux-ide list and the IDE maintainer (see 
Documentation/SubmittingPatches). I don't think it will be accepted because 
this hardware is already supported by the ata_piix libata driver.

That is not a valid reason to reject -- libata is still considered
very experimental for ATAPI devices, which are not enabled by default.

Jeff has said that he prefers (at present) for people with ATAPI drives
to use the IDE layer rather than libata, where possible.

That will change soon, but it's still the case for now.

Cheers

PATA ATAPI, not all ATAPI...
