Re: problems with libata and ICH5 chipset.

[James Courtier-Dutton <James@superbug.demon.co.uk>]

I have managed to fix this myself, but I don't think it is very user 
friendly.
I have to compile into the kernel the option:
ATA/ATAPI/MFM/RLL support -> Include IDE/ATA-2 DISK support

I can leave the kernel CD drivers as modules.

This works, even though I don't have any PATA hard discs.
So, I now have:
hda - PATA DVD-Writer
hdb - PATA DVD-ROM
sda - SATA HD
sdb - SATA HD.

See new dmesg extract:
