Agreed. I am willing to wait for a thought-out solution. Also, the only alternative would be to do it myself :-) >I can't resist, sorry, but let me say that you bought a machine and a >SCSI controller that cannot use more than 16 MB of RAM.

End of story. PCI, you ask? Barely on the market, buggy and not affordable either. -- Volker -- ---------------------------------------------------------------------------- F.D.P. -- reimt sich auf BSE ... Volker A.
