I made an observation that it would be nice to add a "report anything you need to about this target" call to the host adapter code so that the sample logs were deferred until the same time as the SCSI system was matching up drivers. That is, something like: > (bt0:1:0): "FUJITSU M2266S-512 001D" is a type 0 fixed SCSI 2 > sd1(bt0:1:0): Direct-Access 1029MB with 2107704 512 byte sectors > bt0: targ 1 sync rate= 4.54MB/s(220ns), offset=15 That way everything about target 1 is printed in one place. I'm not planning on doing anything like this. Peter -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc. Voice: 508 433 6936 dufault@hda.com Fax: 508 433 5267
