A suggested patch for ICH5-SATA
Hello!
I'm configuring one of the new Intel server (entry level, SR1325-TP1).
I had some "troubles" because of SATA controller not detected in 2.4
neither in 2.6... only if you map into BIOS "LEGACY ATA" (that maps PATA
(for CDROM) and SATA as traditional ATA) 2.4 detects HDs even if it does
not enable DMA.
I think it's only a matter of pci id, I tryied to patch kernel with the
file attached and 2.4 detects it as a SATA and enable DMA. :)
It could be nice to include a similar patch into new kernels...
especially for installation step.
Thank you, Leonardo.
