Well, I definitely know that it is mac5380=, not mac53c9x=. I just don't
remember exactly what the individual arguments really do. The mac53c9x
argument is for the mac_esp driver that is used on many of the later
models, such as most quadras. The mac5380 argument is for the mac_scsi
driver, which is for all the older models that use some flavor of the
NCR5380 chip. The exact argument I gave in the earlier email was the
one that the installer set by default at one point. Based on the
source I have laying around, it looks like the following:
mac5380=<can_queue>,<cmd_per_lun>,<sg_tablesize>,<hostid>,<use_pdma>
They are all optional, but are interpreted by order. The mac_scsi
driver only supports a single bus, so it doesn't need the count
argument that the mac_esp driver uses.

P.S.: It's probably a bit much to say I wrote major parts of the
kernel. I just know a good chunk of it. About the only place you'll
find my name in the source is for hfsplus support, and I don't even
do that anymore.
