I have an aic-7895 onboard a Tyan 1836DLUAN with a DGVS09U that runs at 40 MB/sec, a narrow Quantum viking running at 20 MB/sec, and a Toshiba XM-3702TA CD-ROM running at 4.4 MB/sec. So, at least for me, it seems that you can have a variety of speeds on a single bus (all are connected to bus 0). -- Albert Lai 1018D East Campus Residential Computer Consultant 411 W. 116th St. Columbia University New York, NY 10027 http://www.columbia.edu/~aml61 (212)853-4854 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
