Hej !
Jag har fortfarande inte lyckats med att konfa min Linuxserver f�r att f� den att
funka som installationsserver f�r NetBSD pmax ( till mina Digital DEC 5000/125 . )
Jag har problem med att hitta de filer som jag ska g�ra mina �ndringar i p�
linuxservern som motsvarar det som st�r i installationsguiden .. jag bifogar h�r
nedan installationsguiden med mina kommentarer .. och hoppas att n�gon kan hj�lpa mig
att lyckas .. Jag har kanske lite sv�rt att fatta s� beskriv g�rna noggrant i vilka
filer jag ska �ndra och hur jag g�r det m.m.
Har �ven lite fr�gor ang�ende Bootkernelen samt Avdelningen Notes ( 4 )
Jag skickar detta b�de till Linuxlistan samt till BSD listan eftersom jag har problem
med b�da delar .. Hoppas inte att detta st�r n�gon f�r mycket ...
Installing NetBSD/pmax
--------------------------------------------------------------------------------
Please note: this page applies only to NetBSD-1.3 and later releases of NetBSD/pmax.
Look in the old installing NetBSD/pmax page if you don't see what you are looking for
on this page. Further questions should be sent to the NetBSD/pmax mailing list.
--------------------------------------------------------------------------------
Booting and running NetBSD/pmax over a network requires a BOOTP server, a TFTP server
and an NFS server. (These are usually all run on the same machine.) There are two
basic stages to the boot:
The PROM software sends a BOOTP request to get its own address, the address of the
TFTP server and the kernel to download. After loading the kernel into memory, it
executes it.
The kernel probes and configures the devices, and then sends out another BOOTP request
so it can find out its address, the NFS server, and path. It then mounts its root via
NFS and continues.
1. Setting Up the Server
You will need to set up your server to serve BOOTP, TFTP and NFS.
The NFS setup is quite simple. Untar the NetBSD snapshot or distribution into a
directory on your server and NFS export that directory to the client. You'll probably
want to map root to `root' (rather than the default `nobody') when you export it. A
typical /etc/exports line on a NetBSD system would be:
/usr/export/pmax -maproot=0 myclient.mydom.com
>>>> Jag har lagt till i /etc/exports : /home/je/netbsd/binary -maproot=0
>dec01.almhult.se
For the TFTP setup, copy the ECOFF format kernel netbsd.ecoff from the extracted
snapshot into an appropriately named file (I use netbsd.hostname) in the directory
used by your TFTP server.
I vilken katalog �r det ?? Jag har startat TFTP via inetd.conf ...genom att
avkomentera orginalraden ..
I vilken fil ligger den kernel filen ??
For the BOOTP server you need to specify the:
hardware type (Ethernet)
hardware address (Ethernet MAC address)
IP address of the client
subnet mask of the client
address of of the TFTP/NFS server
name of the kernel loaded via TFTP
path to the root for the client (mounted via NFS)
Here's an example for a Unix system running bootpd:
myhost.mydom.com:\
:ht=ethernet:ha=08002b123456:\
:ip=192.168.1.2:sm=255.255.255.0:\
:sa=192.168.1.1:bf=netbsd.myhost:rp=/usr/export/pmax:
>>>> Jag har kollat upp MAC adressen p� DEC maskinen .. men vad g�r jag sen ???
>>>> Vilken fil ska jag l�gg atill denna info i ?? Beh�ver n�got startas ??
2. The PMAX PROM
This section incomplete!
The only Ethernet device the PROM on most PMAX systems knows how to boot from is the
onboard Ethernet interface (correct?).
Notes on various models' problems TFTP booting...
Model Boot command
5000/xx, 5000/1xx, 5000/240, 5000/260 boot 3/tftp
5000/200 boot 6/tftp
2100, 3100 boot -f tftp()
3. The Kernel
Once loaded, the kernel will probe and configure devices. It will then send out
another BOOTP request to get its IP address and the path to mount its root filesystem.
If you specified the n flag on boot, the kernel prompt on the console for a root
device, dump device and file system type. You may reply to these with a question mark
(?) to get a list of valid options. Currently there is no support for crash dumps on a
system without a disk.
4. Notes
1. One or more of the following options must be specified in your kernel config file.
See options(4).
NFS_BOOT_BOOTP
NFS_BOOT_DHCP
>>>> Ska jag �ndra detta i n�n fil p� Linuxservern ??
2. You will probably need to run swapctl -A -t noblk again in /etc/rc.local (at which
point NFS is up) to activate NFS swap files in /etc/fstab. (Check this! /etc/rc looks
ok).

Hoppas att ni kan hj�lpa mig att lyckas med detta .. vi ska n�mligen vara klara med
detta skolarbete inom en snar framtid .. och vi har inte lyckats installera alls �n
