Booting off 5.3 CD

[jacques brierre]

Hello all and happy new year.

I am running into a rather basic and frustrating problem getting off the 
ground
with 5.3 on an Ultra 2. Can't seem to boot off the CD... I've seen 
references
to various problems in the archives but not this specific one.

yes, I've made another CD... with the same result...
I assume it's the boot-only CD... the docs don't seem to address whcih 
cd does what.
Does anyone know if there is a fix for this?

thanks.
