[wellylug] Error booting from live CD

[Ian Beardslee]

Bingo, thanks for that Pete.

I had noticed after flicking the email off that before it got to that
point it was coming up with a couple of lines describing the IDE devices.
  As it flashed by I had a glimpse of something saying that the hard disk
was using dma and pio and for the cd it had pio and pio.

I had tried 'nodma', but hadn't used 'ide=nodma'.

Sigh ... oh well, shows I was was on the right track - enough knowledge to
be dangerous :-) ... part of the learning curve.

Thanks.

Ian
