EIDE Bus 0 and Bus 1 are identical in their capabilities (and limitations). If you have two three-connector cables, you can indeed install Master and Slave drives on each cable. >> What I am thinking is to use my ATA 40GB Maxtor as the boot drive on ATA buss 0 and use the SCSI HDD in another bay. >> That is certainly possible. >> Another question. Can the 2 SCSI busses use devices with the same ID #'s? >> Yes, if the buses are indeed independent, such as the two mobo SCSI buses on a 7600 or an 8600 or a 9600, say. Or, on the mobo SCSI bus and the ATTO/Apple SCSI card, of an UW-equipped Beige G3, say. >> Example, ID 5 on SCSI buss 0 and ID 5 on SCSI buss 1. >> Not a problem. >> Also, I think that both the factory internal and the external SCSI connectors are SCSI buss 0. Is this correct? >> Yes, correct. The earlier Macs had two buses, an U-SCSI Bus 0 (10 MB/sec), which was internal only, and a SCSI Bus 1 (5 MB/sec), which was internal as well as external. The Beige G3 has only one SCSI bus, Bus 0, and it is 5 MB/sec. [ snip ] -- G-List is sponsored by <http://lowendmac.com/> and...
