Re: [9fans] Re: sata support

i think the problem is that the pci id in your motherboard is not recognized.

i think you will need the following lines added to /sys/src/9/pc/sdata.c and recompile
the kernel.  (to be sure, could you send me the output of pci from your machine.)
unfortunately, this will only be possible if you have another machine with plan 9 installed
on which to work.

if you don't i think this will need to be added to the distribution so a new install cd
can be created.  it's impractical for me to generate them.

i believe this chipset supports ahci.  unfortunately, i don't have one of these motherboards
to develop on.
