[Linux 2.4.32] SATA ICH5/PIIX and Combined mode

[Paul Rolland]

Hello,

I have a machine with two SATA HDD, and one PATA CDRom.
Bios is configured for combined mode, and installing a RedHat ES3
(Kernel 2.4.21-ELsmp) is fine, the two HDD are up, the installation
is fine and the CDRom is working.

Then, upgrading to a vanilla 2.4.32, the ata_piix.c file contains
a "combined mode not supported" and booting the machine hangs, as
no VFS are up for root device.

Of course, I can disable the Combined setup in the BIOS, then I have
my two HDD, but no CDRom... 

What is the "trick" to have a 2.4.32 be able to do what a 2.4.21 was
doing ?

Thanks in advance,
Regards,
Paul
