Knoppix v3.9 LiveCD Help please!

[Simon1980]

Hi all, i'm new to linux, hence trying this LiveCD, i have checked the MD5sum so thats ok and burned onto a 700Mb CDR with Nero. i get to the boot screen ok but after pressing enter the screen just goes blank, i have tried every command in the list virtually and still nothing, the furthest i get is with "knoppix vga=normal acpi=off pnpbios=off noapic noapm and i get this :-


Uncompressing Linux OK booting the Kernel

Frozen from then on.....................

P.S even failsafe has to be used with vga=normal and the it just freezes at " Uncompressing Linux OK booting the Kernel"

Ideas would be GREATLY appreciated

What type of CD-ROM do you have (ATA, SATA, USB, other)?

How fast did you burn the CD? Many CDs have a higher error rate at faster speeds. You could try burning the CD at a slower speed, < 8x.

Also, you may want to check the bugs page for any know bugs with 3.9 and your system. Knoppix is good but it tends to shoot for the middle ground. So if you have very new, very old, or esoteric hardware, Knoppix may need some tweaking.

Let us know what you discover.

rwcitek pointed you in the direction of what I thought it was also when I saw this post. You may want to look over the Downloading FAQ (which includes burning information) in the wiki, found by following the Documentation link near the top of this page. If you come up with some problem that is not in the downloading FAQ we would like to update it to reflect that.

Thanks for the replies guys, well my CD Drive is ATA, i did run the disk on a old PC Celeron 333 256Mb RAM, and it all loaded perfectly, i did burn the CD at about 40x........i think i may try KNOPPIX_V3.6 at 4x and seee if thats happier with my Newer system which dosent make sense but computers dont do they LOL. Any further ideas though really appreciated

...i did burn the CD at about 40x.......

We have seen a lot of strange problems that have been traced back to burns at speeds that high.

Heh... that's a nice way of saying it. I have found that the time it takes to burn an ISO at 12x is just enough to finish a fresh cup of coffee and a buttery croissant. Mmmm Linux...

yeh i can take the point of 40x being a problem but it did work on the Celeron 333 system i put it on if the CD was burnt wrong it wouldnt run on anything surely ?

Not necessarily. Think of the burn process less as being "right" and "wrong" and more in the terms of sloppy sentence construction, e.g. run-on, lack of punctuation, spelling errors, etc. For example, take your sentence above. Is it written wrong? That depends. I can read it and can figure out what you meant to write. But I would not want to read more than a few sentences like that. Had you written it more slowly and carefully, you probably would have caught and fixed your mistakes, resulting in a more readable sentence.

CD writers are the same way. If you burn slowly, you get a better quality burn. If you burn faster, you get more errors, which shifts the burden of figuring out what the data should be to the CD-ROM. Some CD-ROMs do better than others with errors on the CD. Some CD-ROMs can figure it out. Others just give up.

See this thread for a sample of the strange things a high speed burn can cause.
