Well, I do not understand how MacOS is booting from the first ide drive
(ide0). Is it not using OpenFirmware to do this?

Maybe I don't get it but rwd1c should be the entire disk in raw mode. We
need bootxx to be at the very begining, isn't it? Such that the OF can
load and run it. If rw1a comes after rw1b (for example) than I suppose the OF
does not know where to find the loader because he does not understand BSD
disklabel. Am I wrong? Nevertheless I have tried both rw1c and rw1a to
no go. :(

I thought the slave is not supported, not the master on the second
channel. But I have done more tests and this time I used only channel 0
(ide0). See below.

Or maybe bootxx is installed but the OF does not know how to
read from that drive.

Here is a summary of what I have tested (on the ide0 channel):
1) Drives as master (single not with slave and there is no slave on the
cable). IDE HDDs from Seagate, IBM and Quantum.
2) cables: 40 pin and 80 pin cables from various
manufacturers and different lengths. For the 40 pin ones I have with 2
connectors and with one drive connector only (tested both types). The drive
is always connected at the end of the cable. The other end plugged into
the motherboard.
Michael, what cables are you using? Standard length?
3) attached also a DOS drive (seen under MacOS) and used also to test
dir ide0/@0:0,\
Only errors from DIR no real listing of the contents.
With all this it fails to read the disk. Or at least I have not found a
good combination that works.
Maybe your patches from OSX are different from the SystemDisk ones.
Could you please check the patches I attach to this email against yours?
Especially the dev ide0 and dev ide1 ones. Maybe here is the key?
I have attached now a small SCSI drive, installed NetBSD on it and moved
the /usr to the wd1. Now I have / and swap on SCSI and /usr on IDE it
works ok. Booting the SCSI disk (ID 0) with a similar command to the one
you suggested for ide works (0 > boot scsi/sd@0,0 netbsd). BTW when trying
to use 2 HDDs at install time (one for / and one for /usr), I realized
that I do not know how? It is not possible with sysinst?
Thanks.
Best regards,
Gheorghe Ardelean.
