Sysinstall failing to install from CD-ROM

[putnam at speakeasy.net]

    I was trying to use sysintall to install additional packages. When specifying the FreeBSD CD as the source, I get the following error:

Error mounting /dev/acd0 on /dist: Input/Output Error (5)

    Whenever I cat /dev/acd0 or try to mount the device to /cdrom I get the same error.

     What am I doing wrong?


thanks
