Missing file in CD setup

[M.P. van Os]

The installer signals a missing or none-readable file "bsdutils" and advises to reburn
the CD at a lower rate. Downloaded the "warty-release-i386" of 10/20/04 both at the
office and at home. Did not burn a CD but mounted the ISO file with Alcohol 120%. After
failer, burned a CD. (NERO signals: "The entered blocksize does not correspond to the
image length. The blocksize may be wrong. Do you want to correct the value or ignore")
File is still missing.

It definitely isn't missing - if it were, the release would break for everybody,
and it doesn't. I'm afraid you are just going to have to experiment with
different burning strategies, or request a pressed CD from shipit.ubuntu.com.

[Albert Moraal (albmrl-ubuntulinux)]

I too have the installer complaining about bsdutils. I have 3 pressed cd's
shipped by ubuntu and all have the same problem. I mounted the CD's under
Debian. The bsdutils package is on the CD, but it is unreadable, copying it
gives an I/O error.

[Colin Watson (cjwatson)]

I'm afraid this indicates a problem with your CD drive. I/O errors are always
hardware problems of some kind.

[Matt Zimmerman (mdz)]

A common cause for this error is a CD-ROM drive which does not work correctly
when DMA is enabled. For this reason, DMA is disabled by default on CD-ROM
devices in Hoary.

A workaround is to use:

echo "using_dma:0" > /proc/ide/hdc/settings

(replacing hdc with your CD-ROM device if appropriate)

[Martin MacRobert (mjm)]

Where and at what stage of the install do you add this statement?
> echo "using_dma:0" > /proc/ide/hdc/settings

[Colin Watson (cjwatson)]

After the "Detecting hardware to find CD-ROM drives" step, press Alt-F2, press
Enter to activate that console, and type in that command. Press Alt-F1 to switch
back to the installer's user interface.
