Re: [vox-tech] problematic computer (when installing linux) [fixed]

These kernel command-line arguments to selectively disable some of the
sometimes-problematic hardware autorecognition routines (plus ACPI,
etc.) can be really, really useful in installing modern Linux
distributions onto (in particular) older boxes.  Vexingly[1], though,
they _aren't standardised_.  Grrr!

Have a look at the famous "Knoppix cheatcodes" list:
http://www.knoppix.net/docs/index.php/CheatCodes  

As comprehensive as the Knoppix list is, your "novesa" and "ide=nodma" 
appear nowhere on it:  Instead of "novesa", you would say
"xmodule=[SomeModuleName]".  Instead of "ide=nodma", you would say
"nodma".  So, I have to wonder:  Where are these differences between /
among distributions entering into the picture?

The reason this has come forcefully to my attention is that this guy
wrote to me in e-mail, a couple of weeks ago:
http://www.ubuntuforums.org/showthread.php?p=15125#post15125

He's brand-new to Linux, and had found my Web page[2] concerning Linux
suport for the Dell Inspiron 7000 laptop, which he also owns -- and on
which I've run Debian happily for many years.

He attempted to install the Debian-derived Ubuntu Linux distribution,
and got this:

  cdrom-detect: searching for Ubuntu installation media
  ide-cd 0x28 timed out
  hdc: DMA interrupt recovery
  hdc: lost interupt
  hdc: status error 0x58 drive ready seekrequest datarequest
  hdc: status error 0x00
  hdc: drive not ready for command

As it turned out, he was able to get around the problem by swapping
CD-ROM drives for one of a different BIOS rev. (as reported on the
above-mentioned Ubuntu Linux thread), but one of the suggestions I was
going to make was to try the installer with IDE DMA disabled. 

Which begs the question:  How does one do that on arbitrary Linux 
distributions, if they all implement kernel command-line options 
differently?  (Yes, I do know that more-conservative Linux
distributions' kernels disable fancy addressing modes for IDE, by
default.)
