Juts simulating on paper leads to nothing wrong in theory: 1) SCSI/IO INQUIRY 2) TRANS_SETTINGS WIDE=1 SYNC=20MHz 3) SCSI/IO TEST UNIT READY + NEGO WIDE=1 -> 6,600 MB/s (16 bit) 4) SCSI/IO READ CAPACITY + NEGO SYNC=20MHz --> returns CHECK CONDITION 5) AUTO-SENSE + WIDE=1 (not to be stuck with Unit Attention condition) -> 6.600 MB/s (16 bit) 6) ANNOUNCE -> 6,600 MB/s (16 bit) which matches observations, btw. The driver will probably try to negotiate SYNC=20MHz on the next SCSI IO, but this will not be announced and lead to user frustration. ;-) Sorry for that, but I donnot have any immediate solution. Will think about such. But may-be you can check the above by trying the following: 1) Send a TUR from camcontrol -> SIM should silently negotiate SYNC=20MHz 2) Tell camcontrol to read current settings (if possible, is it ?) 3) If result is 40.000 MB/s (16 bit), then practice matches the theory for once. :) Gérard. > On Mon, 3 Jan 2000, Gerard Roudier wrote: > > > > >Hello, > > > >The sym driver gets USER settings of SCSI devices from controller NVRAM > >and reports these values as USER settings to CAM.
