As I remember there was something like: data overrun of XXXX bytes detected followed by various retraining/resetting failure attempts. As I remember no one successfull write's happens. my configuration: ahc0: at 0x1c00-0x1cff irq 11 on eisa0 slot 1 ahc0: aic7770 >= Rev E, Single Channel, SCSI Id=7, 4 SCBs when SCB paging is enabled, this line looks like ahc0: aic7770 >= Rev E, Single Channel, SCSI Id=7, 4/255 SCBs ahc0: target 0 Tagged Queuing Device (ahc0:0:0): "CONNER CFP1060S 1.05GB 213C" type 0 fixed SCSI 2 ^^^^ upgraded sd0(ahc0:0:0): Direct-Access 1013MB (2074880 512 byte sectors) ahc0: target 1 Tagged Queuing Device (ahc0:1:0): "IBM DORS-32160 S84A" type 0 fixed SCSI 2 sd1(ahc0:1:0): Direct-Access 2063MB (4226725 512 byte sectors) As I already say, SCB paging works with any _one_ device alone. -- Andrey A.
