Hi,

I am installing via CD-ROM using a Mitsumi 24x (laptop style)
CD-ROM with mixed success.  I created a bootable CD-ROM
to install 1.4.1.  

Using this configuration, It booted the kernel and when it tried
to load sets, I got errors (DMA IIRC).

On another system with a more-or-less standard CD-ROM, this
was not a problem.  

My guess is the kernel wants always to do DMA and not PIO,
but I am thinking this drive (or related hardware) can only do
PIO. 

Is there a way of triggering it to do PIO?  Or what are any
recommendations...

Thanks....
