   By coincidence I have just seen this problem on an older box, and
followed the installation instructions in Chapter 5.3.1.2
   The screen display "Detect CDROM" is followed by a list of modules to be
loaded, I just pressed <return>, the modules were loaded, then the screen
went mostly blue, followed by an error message reporting a CDROM access
problem.

   I changed to console 2 <alt>F2>
<return> to activate 
cd /proc/ide/hdc
echo -n "using_dma:0" >settings

then return to console 1 <alt><F1> and retry CDROM detection. This brought
up the screen "CD-ROM detected"
