WIth Knoppix 3.3, worked correctly with simple <cr> at the boot: prompt.
With 3.4, a simple <cr> resulted in "the blank screen of nothing".
Thanks to another post on Compaq Presarios, I found that
knoppix acpi=off noscsi
allowed the system to boot properly into the knoppix account running X.
The builtin wireless card doesn't work (31-Jul-2004), but I haven't tried very hard. Waiting for another day.
