I downloaded Knoppix_V3.4-2004-05-04-EN.iso from ftp.uni-kl.de/knoppix
May 4-5 (it took 30 hours, with many resumes), and it failed the
MD5sum test, yet it loads and runs without any error messages after
burning.
When I run the Cdtest "knoppix testcd", two files fail the internal
md5sum check:
/boot/isolinux/f2
and
/boot/isolinux/f3
I went back and downloaded the md5sum from the site a second time, and
it was different from the one I got there before starting the download
yesterday morning:
md5sum of May 4 10:30 (Mountain Time)
49a62cdac7a3afcee0d2d47ea17daa6f *KNOPPIX_V3.4-2004-05-04-EN.iso
md5sum of May 5 14:00
8e9cd4d310ad8381d1ec3326c6caae2b *KNOPPIX_V3.4-2004-05-04-EN.iso
md5sum calculated by dvdsig and winmd5sum on my downloaded iso file:
KNOPPIX_V3.4-2004-05-04-EN.iso,1371e16f4ddab3d3870c0e345e2f11fd
The f2 and f3 boot-up functions appear to perform normally as well,
displaying two screens of the cheatcodes available at boot-up, and
referring the user to others included in the full text file on CD
However, on reading the introductory text in the splash screen after
KDE loads, I found the following errors in documentation:
"System Requirements" requires a "486 cpu or better", but ALSO a
"Bootable CD-ROM drive"
This is contradictory and confusing, as I'm fairly certain there have
never been any 486 systems produced with bootable CD-ROM drives.
Then, in cheatcodes.txt, one finds the following:
"If your BIOS does not support el torito booting from CD, you can
create
a bootable floppy disk by issuing (on Linux)
dd if=/cdrom/KNOPPIX/boot.img of=/dev/fd0 bs=18k
or, in case of DOS, use the rawrite.exe program provided in the
KNOPPIX directory on CD."
AND
"knoppix ide2=0x180 nopcmcia Boot from PCMCIA-CD-Rom (some
notebooks)"
Which further contradicts the need for a bootable CD-ROM.
Unfortunately, these floppy boot directions can't work because there
is no boot.img (nor rawrite.exe) to be found in /KNOPPIX/ (or
elsewhere on the CD).
Happily, Knoppix 3.4 can still be booted without a bootable CD-ROM,
using the boot.img included in the Knoppix 3.3 release of 2004-02-09.
However, this boot image generates a series of "modprobe" error
messages because it references dependency files which don't exist on
the Knoppix 3.4 version. I don't know whether booting with the Version
3.3 boot floppy affects the performance of Knoppix 3.4.
I haven't tried booting from PCMCIA yet.
