Tyan, in > their 2642 SMP manual, recommends that the faster (and > boot) drives be placed on the B bus. Mine aic is far too old to be a dual 160 controller, its part of an ASUS P2B-LS board. As far as I recall, I've never had a B channel (there's no connector for it on the motherboard). I have a 50 pin connector, a 68 pin Wide-SCSI connector, and a 68 pin U2LVD connector (to which my LVD is attached). da1 and cd0 are attached to the 50 pin connector. The motherboard manual says an AIC-3860 transciever is used to bridge the non-LVD devices. > This worked fine for me through builds of 31 Dec; I > discovered with the 20 Feb slice that you could no > longer use both channels with CURRENT. the da drives > would boot from A or B, but when on B, the kernel would > not recognize the DVDRAM on A.
