What gives? ;) Is = it that the MPS driver *and* the MFI driver both support the LSI SAS2108 = chipset, but the MFI driver checks first during boot, so it wins? > _______________________________________________ > freebsd-scsi@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-scsi > To unsubscribe, send any mail to = "freebsd-scsi-unsubscribe@freebsd.org" -------------------------------------------------- Andrew Boyer aboyer@averesystems.com
