Hi ! Someone here has a specific configuration: A VaxII-client, a small 40MB local /root-fs, a old bootserver (only for a short time from now), ult.2.3 and a new bootserver, a DEC 5000-series, with Ult.4.0. In the old days 8) for a restore he just used the old bootserver via network: Booting the client in single-user-mode, restoring the /root-fs and all was ok. The client is NOT diskless. Now, with the old server subject to leave the dep., he has to learn how to boot from the ult.4.0 (MIPS !). We tried the following: - The remote boot uses a node database on the server. We looked at the entries in the old server and set the values on the new one accordingly. - The server-kernel is configured for the use of mop_mon/portmapper and alike. - The netload.sys (primary loader) is the one from the old server. - We copied the /usr/var/adm/ris/vmunix.sys-File containing the Ult.2.3-single-user-system to the new bootserver. It is mentioned in the node database as secondary loader. - The tertiary loader contains a compiled struct with the required informations (server-IP, netmask, client-name, -IP and submask). We created it on the old server to conform to Ult.2.3 headers. (struct netblk, if someone cares :). From the server-syslog, we can see the following on the NEW server: - sending volunteer assistance for system load (target blah) - sending system image - sending volunteer assistance for tertiary load - sending tertiary loader - sending secondary loader - secondary load file too large and it fails with a client console saying Unrecoverable network failure Does anyone has a documentation of WHAT the both nodes exchange during remote boot ? What is supposed to be the the primary, secondary and tertiary loader under Ult.2.3 and ult4.0 ? Well, the DEC helpline meant something about "using the normal ris utility". This requires the boottape which is no longer available (lost in the dust of long-gone centuries :). A new Ult.-Version costs money... Please reply via EMail, I'll summary if there's enough interest. (Yes, I know my writing style is awful. I'm workin' on it :). Thanx in advance ! PI
