Now that the installation is finished, I'd like to boot the
NetBSD
from
the disk but I don't know how.
First I tried to see the content of the HFS
partition on the first and the second IDE disks, but
dir ide0/disk@0:x,\ where x is 0,1,...,10
dir ide1/disk@0:x,\
(pfdisk says that x should be 5 for ide0 and 7 for ide1)
returns the error message can't OPEN the DIR device.
OF 2.x is supposed to support HFS but with 2.0f I wouldn't bet on
anything.
Well, I do not understand how MacOS is booting from the first ide
drive
(ide0). Is it not using OpenFirmware to do this?
It doesn't. It uses /AAPL,ROM to boot which is simply OF calling the
Apple ROM.
MacOS X on the other hand does boot via OF which is why the
installation CD installs patches.
After searching the archives and finding a message from Michael
(macallan@ ---
http://mail-index.netbsd.org/port-macppc/2008/05/02/
msg000119.html)
I have tried the partition 0 boot method but without success (I
reinstalled on the disk after dd-ing the first 1000 sectors with
0). I
copied ofwboot to the root partition, unmounted the wd1a and used
installboot as follows:
installboot /dev/rwd1c /usr/mdec/bootxx /ofwboot
try rwd1a - I keep forgetting which one is the one that works.
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. :(
Depends. We need bootxx where OF thinks partition 0 starts which may
or may not be block 0.
Also, I never tried to boot NetBSD from the 2d IDE disk - I wouldn't
bet on OF even supporting it properly.
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.
Mine boots an OSX CD from the 2nd IDE channel but that's about it.
after rebooting and issuing the following boot command
0 > boot ide1/@0:0 netbsd
I get the following error message: "can't OPEN:"
That looks like bootxx wasn't installed properly, otherwise you
should
see at least output from the loader.
Or maybe bootxx is installed but the OF does not know how to
read from that drive.
Or something in between goes wrong - as I said, OF in general and 2.0
in particular aren't exactly known for producing useful error
messages :/
[...]
If this fails I will put a SCSI disk inside and try also this way.
The beige G3's IDE chip is extremely picky about cables and its
OpenFirmware variant isn't exactly good at dealing with IDE problems.
Please try different ( brand new is possible ) IDE cables. I had
endless trouble with mine, replacements just worked and the old
cables
work fine in a different machine which isn't quite as picky. This
particular OF won't give you any useful error messages regarding
IDE -
it's always 'can't OPEN' or something like that.
Finally - check if the drive you're trying to boot from is actually
the master. Some drives have different settings for single, master-
with-slave, cable select - they might work in NetBSD but OF may
require different jumper settings. Try with only one disk per channel
( it took me some time to get two disks at ide0 to work. The 2nd one
isn't used for booting anything though )
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?
Bog standard 40 wire cables. The IDE chip doesn't support any UDMA
mode so using an 80 pin cable is kind of pointless.
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.
May or may not indicate anything - my beige G3 doesn't list
directories on an IDE CDROM either.
With all this it fails to read the disk. Or at least I have not
found a
good combination that works.
Try putting bootxx into wd0a and see if that changes anything.
Maybe your patches from OSX are different from the SystemDisk ones.
Maybe, maybe not. I never tried the System Disk ones because I never
had MacOS on the G3.
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'll have a look but I rather doubt it. All OSX CDs I tried installed
exactly the same patches.
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).
At least something works :)
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?
Since I didn't have a SCSI CDROM handy I had to netboot my G3 and
install by hand - that's what I usually do so I'm not exactly familiar
with sysinst.
