I will try this later

I added this to lilo and it gets a series of messages that quickly scroll
off the screen

it starts with slave alloc 0
then starts the DV process and goes from state 0 to state 1, gives a
couple errors that I couldn't get and then goes into a loop

the looping messages are

sending INQ
timeout while doing DV command 12
command completed status=0x90000
entering ahc_linux_dv_transition, state=1, status=0x14005, cmd->result=0x90000
going from state 1 to state 1

thanks for your help, I was beginning to wonder since nobody had responded
to my previous messages.
