When looking into papers describing the 815 ANSI-SCSI-standard, this assignment of drives appears to be wrong. 816 The SCSI-standard follows a hardware-hierarchy which says that id 7 817 has the highest priority and id 0 the lowest. Therefore, the host 818 adapters are still today everywhere placed as SCSI-id 7 by default. 819 In the SCSI-standard, the drive letters express the priority of the 820 disk. C: should be the hard disk, or a partition on it, with the 821 highest priority. This must therefore be the disk with the highest 822 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the 823 original definition of the SCSI-standard as also industrial- and 824 process-control-machines, like VME-CPUs running under realtime-OSes 825 (e.g. LynxOS, OS9) do. 826 827 If you like to run Linux on your MCA-machine with the same 828 assignment of hard disks as seen from e.g. DOS or OS/2 on your 829 machine, which is in addition conformant to the SCSI-standard, you 830 must say Y here. This is also necessary for MCA-Linux users who want 831 to keep downward compatibility to older releases of the 832 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than 833 June 1997). 834 835 If you like to have the lowest SCSI-id assigned as drive C:, as 836 modern SCSI-BIOSes do, which does not conform to the standard, but 837 is widespread and common in the PC-world of today, you must say N 838 here.

Some SCSI 1198 devices don't implement this properly; if you want to disable this 1199 feature, enter 0 or 1 here (it doesn't matter which). 1200 1201 The default value is 8 and should be supported by most hard disks. 1202 This value can be overridden from the boot command line using the 1203 'tags' option as follows (example): 1204 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to 1205 4, set queue depth to 16 for target 2 and target 3 on controller 0 1206 and set queue depth to 10 for target 0 / lun 2 on controller 1. 1207 1208 The normal answer therefore is to go with the default 8 and to use 1209 a boot command line option for devices that need to use a different 1210 command queue depth. 1211 1212 There is no safe option other than using good SCSI devices. 1213 1214config SCSI_NCR53C8XX_MAX_TAGS 1215 int "maximum number of queued commands" 1216 depends on SCSI_ZALON || SCSI_NCR_Q720 1217 default "32" 1218 ---help--- 1219 This option allows you to specify the maximum number of commands 1220 that can be queued to any device, when tagged command queuing is 1221 possible. The default value is 32. Minimum is 2, maximum is 64. 1222 Modern hard disks are able to support 64 tags and even more, but 1223 do not seem to be faster when more than 32 tags are being used. 1224 1225 So, the normal answer here is to go with the default value 32 unless 1226 you are using very large hard disks with large cache (>= 1 MB) that 1227 are able to take advantage of more than 32 tagged commands. 1228 1229 There is no safe option and the default answer is recommended. 1230 1231config SCSI_NCR53C8XX_SYNC 1232 int "synchronous transfers frequency in MHz" 1233 depends on SCSI_ZALON || SCSI_NCR_Q720 1234 default "20" 1235 ---help--- 1236 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer 1237 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers 1238 are respectively the maximum data transfer rates in mega-transfers 1239 per second for each class. For example, a FAST-20 Wide 16 device is 1240 able to transfer data at 20 million 16 bit packets per second for a 1241 total rate of 40 MB/s. 1242 1243 You may specify 0 if you want to only use asynchronous data 1244 transfers. This is the safest and slowest option. Otherwise, specify 1245 a value between 5 and 80, depending on the capability of your SCSI 1246 controller. The higher the number, the faster the data transfer. 1247 Note that 80 should normally be ok since the driver decreases the 1248 value automatically according to the controller's capabilities. 1249 1250 Your answer to this question is ignored for controllers with NVRAM, 1251 since the driver will get this information from the user set-up. It 1252 also can be overridden using a boot setup option, as follows 1253 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate 1254 for FAST-20 synchronous data transfer (20 mega-transfers per 1255 second). 1256 1257 The normal answer therefore is not to go with the default but to 1258 select the maximum value 80 allowing the driver to use the maximum 1259 value supported by each controller. If this causes problems with 1260 your SCSI devices, you should come back and decrease the value. 1261 1262 There is no safe option other than using good cabling, right 1263 terminations and SCSI conformant devices. 1264 1265config SCSI_NCR53C8XX_NO_DISCONNECT 1266 bool "not allow targets to disconnect" 1267 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0 1268 help 1269 This option is only provided for safety if you suspect some SCSI 1270 device of yours to not support properly the target-disconnect 1271 feature.
