on a ACER Aspire 9410

I have the following issue when trying to image the machine (manually),
the TFTP is going perfect, but when booting the "kernel"
the machine hang at the line
"Activating PCMCIA ..."

the one just after "Activating USB..."

I am wondering if it is possible to desable the PCMCIA via the Z_auto.cmd
file ?
and how

PS : I made test using Knopix 4.02 it's running if I boot in "knoppix
acpi=off no pcmcia" but hang if I don't...

thank you all,
Pascal S.
