booting openbsd on powermac g3 beige

[SebastianR]

Hi,

I know from the macppc.html page, that only the blue & white powermacs are
suported. However, I just got a powermac g3 beige, and wanted to give it a
try.

I prepared everything for netboot, however, when It comes to load the ofwboot
file via tftp, it stops with an error:

# cu -l /dev/ttyU0 -s 38400

Then I thought, take a look at netbsd, and see how that works out. Netbsd
retrieves the kernel from NFS. After all, that worked well, the NetBSD
installer started to run...

Then I replaced the netbsd kernel with a macppc openbsd bsd.rd file from the
snapshots, and restarted the box. The following is the dmesg:

unfortunately, after that line, the box just freezes.

I had to change the load-base and real-base values in openfirmware to actually
get the ofwboot.xcf from netbsd to load correctly.
setenv load-base 600000
setenv real-base F00000
without that, I got a similar error like the one with the openbsd ofwboot,
therefore I wonder whether I just only need different values for the openbsd
ofwboot?

Well, the box, more or less expected, refused to run openbsd, but I thougth it
might be of interest to someone.

Try using the boot.mac as the boot loader,
Yes you will need nfs for boot.mac to load the kernel I believe my  
setup just exports the root directory and I named  the macppc kernel  
bsd.owmac.

some issues your likely to encounter:
        Once you complete an install to disk you can't actually boot from the  
disk because I have not figured out how to make a working old world
        APM boot loader so you will still need the net booting setup around  
(to load bsd)

        The external SCSI port (if its on the G3) will not work.

        mesh the internal scsi controller will work (I have never tried this  
with IDE so if thats you internal disk your mileage may vary)

        The ethernet controllers on these macs don't age very well if you  
have a supported PCI ethernet card toss that in you wont be able
        to boot from it unless you have fcode on the devices rom (unlikely  
unless its an asante card) and I haven't been sucessful in getting add  
on ethernet cards to boot from the network even if they have fcode.

It sounds like a long list gotchas and it is. But I am not sure any of  
the unix-like OSes that claim compatibility with the beige hardware  
really work all that well.

Hi,

nfs was already there, no big deal. However, I tried loading the boot.mac file
from snapshots and from 4.4, both failed:

Disks doesn't really matter. It would be just fine, when it would run diskless
at all. I still had a SCSI disk around and replaced the IDE disk with it.
However, the bsd.rd freezes just after initializing the RAM disk.
The ordinary bsd kernel boots just fine, up to the point where it asks for a
root device. I enter bm0, but then it freezes, while trying to boot from nfs:

... same as with the bsd.rc
"ATI Mach64" rev 0x5c at pci0 dev 18 function 0 not configured
/dev/ksyms: Symbol table not valid.
softraid0 at root
bootpath: enet/netbsd
string [/netbsd] not found
Warning: bootpath unrecognized: enet/netbsd
root device: bm0
nfs_boot: using interface bm0, with revarp & bootparams

I have rarpd and bootparamd running on the console in debug mode, but nothing
shows up in their consoles. I guess I should see there sth. showing up?

Actually,I think I forgot to mention, to get tftp working at all in the
beginning, I had to add a static arp entry for the G3.
On the server now runs everything:
dhcp, rarpd, bootparamd, nfsd and tftpd.

Maybe I've just too few memory in the box?
