For example, a FAST-20 Wide 16 device is 1073 able to transfer data at 20 million 16 bit packets per second for a 1074 total rate of 40 MB/s. 1075 1076 You may specify 0 if you want to only use asynchronous data 1077 transfers. This is the safest and slowest option. Otherwise, specify 1078 a value between 5 and 80, depending on the capability of your SCSI 1079 controller. The higher the number, the faster the data transfer. 1080 Note that 80 should normally be ok since the driver decreases the 1081 value automatically according to the controller's capabilities. 1082 1083 Your answer to this question is ignored for controllers with NVRAM, 1084 since the driver will get this information from the user set-up. It 1085 also can be overridden using a boot setup option, as follows 1086 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate 1087 for FAST-20 synchronous data transfer (20 mega-transfers per 1088 second). 1089 1090 The normal answer therefore is not to go with the default but to 1091 select the maximum value 80 allowing the driver to use the maximum 1092 value supported by each controller. If this causes problems with 1093 your SCSI devices, you should come back and decrease the value. 1094 1095 There is no safe option other than using good cabling, right 1096 terminations and SCSI conformant devices. 1097 1098config SCSI_NCR53C8XX_NO_DISCONNECT 1099 bool "not allow targets to disconnect" 1100 depends on SCSI_ZALON && SCSI_NCR53C8XX_DEFAULT_TAGS=0 1101 help 1102 This option is only provided for safety if you suspect some SCSI 1103 device of yours to not support properly the target-disconnect 1104 feature.
