There was a program on the -10 called DTELDR that was used to boot or dump -11's connected via the DTE. There is a reference in the DTELDR stuff to being able to load a DN20 via its serial console that would be connected to a serial port on the main rsx20f front end. There is another program called NETLDR that used a subfunction of the node. uuo to get notified of ANF boot requests for non-DTE connected remote stations. A DN200 would have transmitted an ANF boot request and the DN20 would have passed that request through to the -10. The ANF code on the -10 would then ring the doorbell of the NETLDR program running in user mode on the -10. Later Mark Hittinger Earthlink bugs@netcom.com ###### From: "Michael L.

So it could boot from _either_ the DTE or the console line? One DN20 had a 1Mb link to a VAX-11/785. Would it have booted ANF-10, but then talked DECnet protocol over the DMR-11? Do any of the rescued tape images contain docs specific to this stuff? ;) -mikeu ###### From: bugs@netcom.com (Mark Hittinger) Newsgroups: alt.sys.pdp10 Subject: Re: booting a DN20, DN200 Date: 30 Aug 2001 17:35:05 GMT Organization: MindSpring Enterprises Lines: 25 Message-ID: <9mltg9$7lu$1@nntp9.atl.mindspring.net> References: <3B8D4B14.CC6F0D20@osfn.org> <9mjku6$had$1@slb2.atl.mindspring.net> <3B8E76DD.9C416DD9@osfn.org> NNTP-Posting-Host: c7.ae.21.58 X-Newsreader: NN version 6.5.0 CURRENT #121 Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!news-ge.switch.ch!news.maxwell.syr.edu!newsfeed1.cidera.com!Cidera!cyclone2.usenetserver.com!usenetserver.com!newsfeed2.earthlink.net!newsfeed.earthlink.net!news.mindspring.net!not-for-mail Xref: chonsp.franklin.ch alt.sys.pdp10:6583 "Michael L.

Yes, there is also a boot11 program that boots 11's over their console line from an image on the 10 (assuming a serial to serial connect). >One DN20 had a 1Mb link to a VAX-11/785. Would it have booted ANF-10, >but then talked DECnet protocol over the DMR-11? >Do any of the rescued tape images contain docs specific to this stuff? Yes look in dteldr.* netldr.* boot11.*, etc. Dunno if the DN20 would have talked DECnet protocol, but it could have talked MOP/ddcmp to it depending on the boot rom it had. You can also look on the second save set on the operating system tapes for the -11 code. There is discussion in there about a special ANF boot rom for the -11's connected to -10's and I'd assume that a newer boot rom would have been used on the VAX so that the DN20 could do a MOP boot (ddcmp).

It could have run the dreaded "MCB" (DECnet Phase III routing) code. I seem to recall that ANF nodes could have links to DECnet nodes, and you could do communication (of some sort) using "TSK" (task?) devices on the '10.
