Andreas, I know how to boot a CD-ROM in a VAX. I've got the VMS 7.2 hobbyist, VMS 7.2 regular distrib, and VMS 7.3 regular distrib, and when I boot them all, I just go into standalone backup. I thought maybe there was some "trick" I didn't know about to boot into a regular VMS system. - Bob -----Original Message----- From: cctalk-admin(a)classiccmp.org [mailto:cctalk-admin@classiccmp.org] On Behalf Of Andreas Freiherr Sent: Wednesday, May 29, 2002 11:20 AM To: cctalk(a)classiccmp.org Subject: Re: How do VMS Condists work? Bob, to PC users, this may sound like I am joking, but I am serious: to boot VMS from CD, you do the same things you would do with any other disk (isn't this what abstraction layers are good for?): assuming that your CD ROM drive is DKA400 because you selected SCSI ID #4, you will insert the disk and issue the command at the console prompt. That's it! - No magic with a special BIOS that would need to support SCSI or CD booting or other wizardry. A VAX can even be booted directly from tape, but this will normally take you into the standalone backup (S/A backup), a reduced functionality operating system that is only made for restoring backups in cases where no other operating system is available for use. Alphas do not have this feature any more. Regards, Andreas Bob Lafleur wrote: -- Andreas Freiherr Vishay Semiconductor GmbH, Heilbronn, Germany http://www.vishay.com

I did try alternate roots, as that was my first thought also. But it didn't work. Actually, the discs don't even look to have the files necessary for a "full" (or even minimal) VMS system to run from CD-ROM. -----Original Message----- From: cctalk-admin(a)classiccmp.org [mailto:cctalk-admin@classiccmp.org] On Behalf Of brian wheeler Sent: Wednesday, May 29, 2002 11:48 AM To: cctalk(a)classiccmp.org Subject: RE: How do VMS Condists work?

I'm pretty sure the OpenVMS VAX V7.3 CD will boot into a minimal OpenVMS system. -- Eric Dittman dittman(a)dittman.net Check out the DEC Enthusiasts Club at http://www.dittman.net/

Interesting. Have you reported that to Bob Supnik? Also, have you tried a recent TS10? I've tried the last couple of development releases and have even been able to get the DELQA emulation almost going (I can ftp in and out, and telnet out, but telnet in only works if you are telnetted out). -- Eric Dittman dittman(a)dittman.net Check out the DEC Enthusiasts Club at http://www.dittman.net/

The site is ftp.firesword7.net, in /pub/ts10/develop. -- Eric Dittman dittman(a)dittman.net Check out the DEC Enthusiasts Club at http://www.dittman.net/

I just tried, my VAX 7.2 VMS CD also boots into a minimal VMS from SYS1 on my MicroVAX. So I guess they changed it between 7.1 and 7.2. - Bob -----Original Message----- From: cctalk-admin(a)classiccmp.org [mailto:cctalk-admin@classiccmp.org] On Behalf Of David Barnes Sent: Thursday, May 30, 2002 8:11 PM To: cctalk(a)classiccmp.org Subject: Re: How do VMS Condists work? Hmmm would like to see that... My latest VAX cd distro is 7.1, but I am current on the Alpha platform.. must have changed along the way then... cool. Bob Lafleur wrote:

I haven't tried the latest version (2.9-9) and, as I run on Linux/Alpha there may be issues with this too - I had to turn optimization off to get it to run.
