Problem: GX620 boot from CD problem
I have Dell OptiPlex GX620, intel Pentium 3.2 GHz 2MB L2 cache, 945G Chipset, 1 gig DDR2 Ram and 160 GB Sata hard drive.
When I try to boot Linux Knoppix 3.9, I get the error
"Kernel Panic: Unable to mount..." etc.
I tried setting the SATA drive to combination but even then it doesn't work although the same error doesn't show up.
Please help

Verifying of md5 checksum and burning a CD at slow speed are important.

I apologize if this has been asked before or I have posted this in the wrong forum.
My problem is not HDD install. My knoppix can't boot from the CD.
I tried to search the archives but I couldn't find an answer. Please help me.

My point was that your choice of topic lines is so poor that it makes your post useless for anyone searching the forums. And it will not attract the attention of the people who know the answer. I suggest that you go back and edit your first post and change the subject from "problem" to something informative and specific that may better attract help. Titles like "OptiPlex GX620 boot bug", "Kernel Panic: Unable to mount" or "booting SATA drive" convey useful information. If everlyone selected topics like "problem" the forums would become useless.

I have SATA hard drives. When set to normal, the following happens
USB/firewire devices ... done
Accessing CDrom
Later
USB/firewire devices ... done
Can't find Knoppix filesystem, sorry.
Dropping you to a (very limited) shell.
Press reset button to quit.
Additional bulletin commands available
cat mount umount
insmod rmmod usmod
knoppix#
(Cursor keeps blinking but keyboard does not work)
When the hard drive is set to Combination
hdc: Status error: Status = Ox58 {DriveReady SeekComplete DataRequest}
failed opcode was unknown
hdc: drive not ready for command (these three lines appear quite a lot of times)
end - request: I/O error, dev hdc secor 21932
cloop: Read error at pos 8233652 in file /cdrom/knoppix/knoppix, 28814 bytes lost
cloop: erro - 3 uncompressing block 745 65536/0/28814/0 823365 - 8262466
Kernel panic - not syncing. VFS. unable to mount root fs on unknown block (1, 3)
(After this the computer hangs)
Please help me.

Have a look at Cheatcodes:Tips&Tricks. Which of the two boot commands did you try, and how far in the boot process you were able to get?

I tried both. The message comes
Starting interediate shell stage 1 as requested by "debug" option
Type "exit" to continue with normal bootup
The cursor keeps blinking but I can't type anything.
This comes in both the boot options
Edit: I hadn't downloaded the md5 and asc files. Now I have downloaded them. Right now I have five files on my PC,
KNOPPIX_V3.9-2005-05-27-EN.iso.md5
KNOPPIX_V3.9-2005-05-27-EN.iso.md5.asc
KNOPPIX_V3.9-2005-05-27-EN.iso.sha1
KNOPPIX_V3.9-2005-05-27-EN.iso.sha1.asc
MD5SUM
Which one do I burn on to the CD and how? The FAQ only seems to tell how to burn the ISO file onto the CD.

Have you tried the link that UnderScore recommended? That is, have you verified the md5sum of the ISO file you downloaded? If you have and the md5sums match, have you tried burning a new CD slowly, < 8x?
While it is possible that you have some esoteric hardware that Knoppix doesn't recognize, the most likely reason for Knoppix not booting correctly is because of what UnderScore mentioned: a bad CDR.
Let us know what you discover.

I have the same computer configuration, a Dell Optiplex GX620. Actually, I have three of them. I get the same set of errors as sid_galt gets on all of them. The same CDR works fine on several other computers (an older Dell model, some Gateways, some whteboxen, etc.), so I do not believe it's the CDR. Tried to boot with debug, and I get a prompt at which I cannot type anything. I checked the MD5 of the ISO and it matched. I suspect it is something paticular to this model of Dell. (I'm also having trouble getting the latest version of the Norton Ghost "Recovery" disc to function in these machines, which is why I'm exploring the Knoppix Live CD.)
JOhn.
