:Is it possible to boot a 4D/35 from a 4D/25 disk?
:I have the following systems:
:A working 4D/25
:A non booting 4D/35 (corrupt harddisk?) with password on PROM.
:If possible, I want to boot the 4D/35 somehow and disable the
:PROM password. Then do a new install on the 4D/35.
No and Yes. No, you can't do it directly (e.g. by inserting the
4D/25 hard disk into the 4D/35.) Yes, you can do it indirectly, but it's
Probably the easiest approach is to take the harddisk out of the 4D/35 and
add it as a second drive onto the 4D/25. Start up the 4D/25 normally,
and use it's root to partition and mkfs the 4D/35 disk as appropriate.
Also use dvhtool on the 4D/25 to add /stand/sash to the 4D/35 disk's
volume header. Mount the root and usr filesystem of the 4D/35 as (say)
/4d35 and /4d35/usr
Then, on the 4D/25, start up
inst -r /4d35 -m CPUBOARD=IP12 -m GFXBOARD=ECLIPSE -m SUBGR=ECLIPSE
(I'm assuming here that you have G or TG on the 4D/35 and not Elan.)
Select whatever products you need, and allow the installation to
After everything is installed, leave inst, and then execute the command
chroot /4d35 autoconfig
to build the unix kernel for the /4d35 subtree.
Now, swap the 4D35's disk back to the 4D35 machine (after shutting
down the 4D/25 cleanly ;-) ). Boot through with the new disk on the 4D/35.
When you come up on the new OS on the 4D/35, execute the command
to *re*rebuild the kernel, and reboot with that. This is necessary
because the kernel built on the 4D/25 might have the wrong disk references.
Once you are all up and able to log in the 4D35, log in as root and execute
nvram passwd ""
This will clear the PROM password.
