I apologize for my previous reply, it was poorly formatted, not 
proofread and also, not sent to the group. I am still trying to figure 
this out. I hope this one went to the right place. If I've doinked it 
*again*, I'm sorry, *again*, and I'll be back in a bit after I've 
re-read some instructions.

I'll also admit I'm very excited to be here, I honestly didn't think 
this place would still be active, and the google groups situation made 
me think Usenet was burning down! I was obviously mistaken.

To answer the question, yes, the CDROM drive is attached to the Symbios 
57c875. Another of this board's quirks is the IDE connectors have been 
removed entirely.
