I'm curious how the new driver handles numbering.

You said in your first mail that drives are numbered by
probe order?  I have two 4 gig IDE drives, both
single masters on separate channels.  I'm only booting
from the first one, so that's not a problem, but the first
is called wd0 and the second wd2.  My kernel config is as follows:

controller      wdc0 at isa? port "IO_WD1" bio irq 14 flags 0xa0ffa0ff
disk            wd0 at wdc0 drive 0

controller      wdc1 at isa? port "IO_WD2" bio irq 15 flags 0xa0ffa0ff
disk            wd2 at wdc1 drive 0

This way I can stick a slave on the first controller and it won't
change the numbering.  I may be missing something though.

anyway, what will the new driver call my second hard drive?
and can I wire it down to be wd2? 

Would this be all I add to my kernel config?

controller 	ata0
device		atadisk0	# ATA disks

or do I need a device for each drive?

I'm also assuming that this thing will work fine with Vinum?

Thank you.
