Shuttle SN78SH7 - success, and starting AHCI driver port from OpenBSD.
I've upgraded my test boxes to a new generation. The Shuttle SN78SH7
barebones (meaning one must buy the cpu, memory, and drives separately),
with a Phenom x4 cpu pretty much just works. Everything probes and
it boots up without complaint. Dmesg output is here:
This baby doesn't have any PS/2 connectors. The keyboard/mouse is
all USB, and does appear to work just fine.
I also went with both a SATA HD and a SATA DVD-RW, so no IDE stuff at
all in my box.
I got the whole mess from newegg.com, it was delivered smartly and
ridiculously cheap for the horsepower it represents. I already had
the hard drives. Everything else came to less then $600 per box
(shuttle, cpu, memory, DVD-RW).
In anycase, the major reason for updating was to get some test boxes
worked up with native AHCI hardware so I can port the OpenBSD AHCI driver.
So I am now officially porting that driver and I expect to have it done
for our July release. OpenBSD has a very nice implementation which fully
supports command queueing and being able to separate out the AHCI
support from the NATA driver will allow us to slowly phase-out the NATA
driver for all-SATA systems. I also think we can get removable SATA
working (something we want since ESATA is becoming the new standard for
external hard drives).
