I modified sdata.c. Added the device id, which was 27c1. I can provide the whole pci output from Solaris. Its rather long. Then the kernel seemed to recognize it once i added the id. I'll look at the other file. The only other computer I have is a work PC that I installed VMWare server onto and got plan 9 working there. So it looks like VBlade is my best option. I found a live CD and i'll have to find a windows client. I am hoping I can export the whole disk, not just partitions. Then maybe use a physical disk in Vmware and have Plan 9 partition, but that may be a pipe dream. To be complete if anyone else finds this post. I am using a dell xps 200. It has the intel 945g chipset. It seems that the dell bios has two modes for the sata operation. AHCI and ATA. No other options are given. Neither work with the standard kernel at this time. Once I get it working I'll post exactly everything I did, in case someone has a similar problem. I'll also see about adding the dev id's to the code base. Thanks for the suggestion Bob
