If I am wrong please correct me. | Well that sounds like you should not have a problem. Try turning off DMA for the CDROM in BIOS... That is there should be a setting for the Secondary IDE controller and the corresponding devices. Normally the defaults say something like AUTO. You'll have a DMAxxx choice and a PIOxxx choice select PIO instead for the CD-ROM. You might want to initially do this to the hard drive too until you get Linux running. |>By turning off DMA on either the hard drive or CD ROM everything |>works... | |Do you mean that start the Mandrake-Linux 8.1 and turn off DMA |in BIOS. Or |start the PC, turn off DMA in BIOS and re-install Mandrake-Linux 8.1 | Try turning it off in the bios as I indicated. LM8.1 re-enables it automatically which may also be a problem, I do not know offhand how to get LM8.1 to disable it during installation.

It may simply be that the computer itself is problematic. Linux has a tendancy to push machines far more than Windows does. A computer that is stable in Windows, may fail to work at all in Linux. This is not Linux's fault, but rather that Linux trys to eek out every last cycle of performance it can. Linux will often bring out RAM and Motherboard problems where Windows does not. Just a thought. |>Bring up LM8.1 in text mode (initlevel 3) and kill off |KDM/GDM if it is |>running. | |Is it in Safe-Mode. I am not skill enough using |combination-key without a |mouse. Which command shall be used to kill off KDM/GDM ? | "safe mode???". Do you mean single user mode? If so "init 3" to NOT start KDM/GDM and then log in and run "mouseconfig". If you get the graphical login screen press CTRL-ALT-F5 (or F1) to get to the text login and type... "init 3" then log in again and run mouseconfig. |>Then run mouseconfig to re-configure the mouse in text mode. | |Is it in Xterm window or any window ? | Your really don't want to be running X while you are trying to fix this. -JMS
