:( Knoppix 3.7..3.9 hang on my Toshiba Satellite 1800-400 laptop by booting:
My harddisk partioning table looks corrupt. Only winxp en winme have no problems
by knoppix 3.7 with kernel 2.6 (knoppix26) don't hang and with fdisk I can see the harddisk table only mounting is not posible
With knoppix 3.9 failsafe works but with fdisk I can't see /dev/hda only in low resolution
Perhaps there is a solution for this problem
Can you boot with boot: knoppix 3? Do you get a shell prompt? If you do, can you post the results of 'cat /proc/partitions'?

With Knoppix 3.2 there where no problems. The harddisk was fully accessable.
The contents of /proc/partitions was:
~Code:major minor #blocks name
3 0 14749056 hda
3 1 6160896 hda1
3 2 1 hda2
3 5 5630751 hda5
3 6 2955928 hda6
~
With later versions of Knoppix I have problems with accessing my harddisk
with 3.8 and 3.9 knoppix hang by booting on: "scanning for Harddisk partitions and creating /etc/fstab..."
Hopefully there is an option by booting

If I understand you correctly, the above was created with Knoppix 3.2. However ...Quote:

Just type 'exit' at each shell prompt to move on to the next stage. You will know that you are at the final stage when typing 'exit' does not do anything. If you get that far, type 'init 5' to go into graphics mode.
How far do you get?

With knoppix 3.8 and 3.9, I must stop at stage 3 else the computer hang on the known failure point.
In stage 3, I can give command: init 5 ; startx
To go to X11. But startx stops with error message
When I give the command: cat /proc/partitions the output is:
when I give the command: fdisk /dev/hdaCode:major minor #blocks name
3 0 14749056 hda
240 0 1966656 cloop0
The computer hangs and display continuely: "hda: lost interrupt"
When I boot knoppix 3.9 with the command: failsafe
Knoppix startup very quickly in grafical mode
Only the harddisk is not recognized.
The commands: 'cat /proc/partitions' and ' fdisk /dev/hda'
gives the same output as above.
Now I can break simple the console application: fdisk
Sorry not a possitiive result

So with the knoppix boot label you only get to stage 3 ...Quote:

Hello Robert,
1.
Here the requested outputs of knoppix 3.9 after:
dmesg | tailCode:hdparm -Cbvg /dev/hda
multcount = 16 (on)
IOSupport = 0 (default 16 bits)
Unmaskirq = 0 (off)
Using dma = 0 (off)
Keepsettings = 0 (off)
Readonly = 0 (off)
Readahead = 256(on)
Geometry = 29264/16/63, sectors = 29418912, start = 0
Drive state is: active/idle
Busstate = 1 (on)
.... the rest is for other things such as CD: ISO9660 memory etc ...Code:FAT: invalid media value (0xcd)
VFS: Can’t find a valid filesystem on dev hda.
2.
When I start up knoppix 3.9 with option ‘no dma’:
Knoppix fb1024x768 screen=1024x768 no dma
Then the laptop startup normally but the harddisk is not accessable

Just a thought.
The Cheat Code to disable DMA is 'nodma' not 'no dma'.
:( Sorry but with the command: knoppix nodma the system is hanging on the same point.
But with the command: knoppix no dma the system is booting so as told
As seen in your post:Emphasis mine.Quote:

'knoppix no dma' with a space between 'no' and 'dma' does not disable DMA but instead enables it. None of the Cheat Codes have spaces in it.
