Nice! I recently tried out NetBSD-6_BETA2 on my LG NAS (MARVELL_NAS) that has
a mvsata(4) controller. Currently it only detects my single harddisc but ithe
machine also has a 2nd harddisc slot and a SATA DVD burner attached.i

How hard would it to implement this? Is the SATA multiplexer driver specific?
or do you need some docs on the multiplexer first?

I'd be most willing to test out some code! ;) Even if it just detects all and
only allows the 1st drive to work as it does now.

With regards,
