Somehow my copy of my openvms73.iso became corrupt. Bunzip2 said there was a problem and I tried to recover and it didn't work. So I need to get a new copy of the file. My license PAK runs out in November too. DO I need to go to Hoff's site with my registration number to get HP to let me download a new copy?

Request new License PAKs from the web form, I think the current one on one of the other threads.

In that will be an e-mail address to request information about downloading kits. It is a new address from the older one, so I do not know what it is.

While Hoff's site has a lot of useful information for hobbyists and professionals, it has nothing official to do with the Hobbyist Program that I know of.

What makes you think your openvms73.iso is corrupt?

The OpenVMS73.iso and most other downloaded VMS alleged ISO files are not really ISO files and trying to analyze them as ISO files will fail.

These files are disk images for the Native VMS format, except for the IA64 boot install disk.

These need to be burned as a disk image.

bunzip2 should not have any idea of what a VMS native file image, and I would be surprised if bunzip2 would produce anything useful from a real ISO 9660 disk image. As far as I know, ISO-9660 predates the bzip2 compression.

The IA64 boot install disk is a dual format Native VMS / ISO-9660 El-torito disk format. And a utility to copy the IA64 disk will totally miss copying the native VMS portion of the disk image, which will result in a useless disk.

bzunip2 has always unzipped this file. .iso or not. I understand it's not ISO 9660. That's for simh compatibility. Not this time though and it said run recovery. So I did and as things were being checked an error was reported. all the recovery files were combined into a file again and the same thing. Why would it all the sudden not want to bunzip the file that was bzipp'd?

Usually HP uses ZIP/UNZIP not bzip2 for the files they transfer.

I do not remember if I posted a screenshot of the FTP directory, or what the file types are.

I am quite sure that I have never used bunzip on a VMS distribution, so have no idea how well that works.

SimH/VAX uses disk images and does not care if the image is ISO format or named .iso.

The files are have the .ISO extension primarily either because some ancient CD-Burner software wanted disk images named that way even if they were not ISO format, or someone made an error and assumed all CD-ROM images should be named .iso.

in case it helps, i did a checksum on my OpenVMS VAX 073.iso and the results were:

MD5SUM: 6D665D72B2D5A0B811B5854EB3204C89
SHA1SUM: 3D89D5DDD29FF4B55827812CA38D58057854D0F7

perhaps that might help you confirm if the file you have is in fact corrupt or intact.

I'm not sure how the file was originally distributed to you, but I can confirm that this .ISO cannot be unpacked with bunzip2 or unzip.

cheers, wizdude.
