Erik thank you for your calm-dowmed reply.☺ I know you are doing good job for ahci mode SATA driver for Plan 9.
I still have problem with detecting CDROM by the formal distribution driver.(Asus P5K-VM) So, I tried your 9atom.iso, and got good feeling with this. Yes, the CDROM was detected successfully! Up-to-now, I only aplied /sys/src/boot/pc drivers, and found strange behaviour of that, say missing 'other' partition in a SATA HDD(only this partition). It has many partiotions, such as 9fat, fossil, arenas0, isect0~3, swap, cache, nvram and other). Then, I used /disk/prep, which reported right partioning, and write it to the disk. Then, I can use other file system. However, when I rebooted the system, then, 'other' partition disappears again. Do you have some idea what's going on here. Kenji
