Corrupted isolinux.cfg in AlienBob's -current ISO?
Hello fellow slackers;

First off, thank you AlienBob for your time and work on all things Slack.

I just downloaded AlienBob's ISO image for Slackware64 current, dated OCT02, and am unable to boot from the created DVD.
Upon boot, isolinux loader shows error messages:

- "Unknown keyword in configuration file: Gh"
- "No DEFAULT or UI configuration directive found"

Having looked into /isolinux/isolinux.cfg , showed that it seems to be corrupted as it should contain legible text, but actually holds 'mojibake' and non-printable characters.

Donwloaded ISO checks out MD5 ok.

Anyone else ran into this or am I doing something wrong?

If the downloaded ISO checks OK then how does the Burnt image checkout?


CdromMd5sumsAfterBurning <- 'Describes some ways to check the validity of a burnt CD, either via the md5sum or via cmp (compare)'.
Hope this helps.

Hello, OneBuck, and thank you for the pointer. For the time being, however, I am limited to a Windows machine, and haven't found tools that can do the job. The info is useful for future reference, nevertheless.

In that case, I suggest try using ImgBurn on the MS Windows machine. Burn at a slower rate 2x or 4x for the image. You can use the compare function that imageburn provides;

From ImgBurn;
ImgBurn is a lightweight CD / DVD / HD DVD / Blu-ray burning application that everyone should have in their toolkit!
It has several 'Modes', each one for performing a different task:
  • Read - Read a disc to an image file
  • Build - Create an image file from files on your computer or network - or you can write the files directly to a disc
  • Write - Write an image file to a disc
  • Verify - Check a disc is 100% readable. Optionally, you can also have ImgBurn compare it against a given image file to ensure the actual data is correct
  • Discovery - Put your drive / media to the test! Used in combination with DVDInfoPro, you can check the quality of the burns your drive is producing

I use ImgBurn when ever on a MS machine with no problems or issues.
Hope this helps.

For some reason, that ISO image was unusable. I mounted it locally, on the server, and got garbage. I have re-created it, and it looks OK now.


_gin 10-05-2013 04:58 PM is been making iso images from current, you may give It a try as well.
