i will be releasing an intel 63xxesb ahci driver within a week or
so. if you would be willing to help me with that chipset (i have
no ich7m hardware), it should be no problem.

coraid is pleased to release an intel ahci driver for the
63xxesb chipset. it's available at /n/sources/patch/sd63xxesb.

this driver supports hotplugging including suprise removal
for all 6 ports. in phoenixbios you need to enable sata and
enhanced mode but do not need to enable ahci. your bios
may vary.

the 63xxesb hardware appears to perform well. with samsung
spinpoint drives, i was able to exceed 80MB/s read with little
system load.

the driver also has atapi support code, but this is untested except
by sata analyzer. (i don't have a sata cdrom.)

i believe the varients of ich7/ich9 which support ahci should
also be supported if you add the did for the device in question.
i did add did 0x27c[45] for the 82801g[bh]m (ich7) controller.
this device is untested.

Woot. I'm starting to really like Coraid :-)

Now the real question: How do we get Coraid interested in USB 2.0
drivers? ;-)

There are USB 2.0 drivers in the works, just not publicly released, as usual.

I'm pissed that the ESP interface is not out either, I'm ready for the
mind meld, I want to talk to Glenda telepathically. Or maybe
telepathetically?

Man oh man. These people who work for free, on drivers, and don't put
out -- what's with these guys?

:-)

I heard they're all secretly porting Linux to Plan 9.
