Sorry, I directly mailed to Nigel. This is the mail that Nigel reply to.

I can use NetBSD on my Performa 630 without SCSI devices using kernel with IDE 
patch, which were made by Takeshi Shibagaki. (Please refer "Re: AV Weirdness".)

SCSI HD or other SCSI device is needed to install, but NetBSD can work without 
SCSI device after the install.
My install procedure is as following.

1) Make "root & usr", "swap" and "MacOS" patitions in IDE HD.
2) Boot NetBSD (netbsd+wdc+espfix-1.5Y) in SCSI HD.
3) newfs /dev/wd0a (="root & usr" patition in IDE HD)
4) mount wd0a.
5) "pax" binary files to wd0a.
6) MAKEDEV all. (IDE patched MAKEDEV)
7) Boot from "netbsd+wdc+espfix-1.5Y.gz" in "MacOS" partition with a check in 
"ask for alternate root/swap?".
8) select "wd0a" for root in the booting process.

I used "Booter1.11.5a3" and "Booter2.0.0a3".
However, I can not directory boot kernel in IDE HD.
Do these Booters support booting from IDE HD?

A check on ATA for Root device works, but did not automaticaly select wd0a.
I am very happy if booter can recognize wd0a as a root.
Is it possible?
