Yes. "Enhanced mode" is how it is listed in the BIOS.

No RAID, just enhanced mode (SATA 3.0 + IDE)

Standard build = standard IDE + Intel PIIX + SATA + Intel ICP

built in in all cases.

No. Seems related to the chipset problems. If I say "root=/dev/hda2" I have better not be getting errors claiming device 08:13 could not mount as root. memory corruption?
The melted flash seems power related (like pin 20 was live for some reason on a standard IDE).
