In fact most PCs these days have. It would be a stupid solution nevertheless. (We also don't "select EXT3".) There are other possible solutions. For example the split of the SCSI Kconfig menu which has been proposed some times before. Provide one menu for highlevel protocol-type options, and one menu devoted to SCSI transports and interconnects. This underlines the central role of the SCSI midlayer and SCSI highlevel in the kernel, and makes it easier for people to spot that they need the SCSI highlevel even for their non-SCSI hardware. menuconfig "SCSI command sets (for HDDs, CD/DVD-ROM/R/W, tapes, scanners, and more)" tristate SCSI help This is for [alls sorts of] internal and external devices, [e.g. this and that]. This option is also required for a variety of hardware which isn't actually SCSI hardware. You especially need this option for [such and such common kinds of non-SCSI hardware whose drivers make use of the SCSI subsystem]. If unsure, say Y. (SCSI midlayer options follow) (SCSI highlevel options follow) endmenu if SCSI menuconfig "SCSI transports and interconnects" bool SCSI_LOWLEVEL help Most of the SCSI transport protocols and interconnect drivers are configured here. Some SCSI transports live in other menus. [obligatory SBP-2 reference] (SCSI lowlevel options follow) endmenu endif SCSI PS: It seems only libata users have difficulties to configure SD correctly. USB users apparently and FireWire users definitely never had that problem. The "select SCSI" in libata's Kconfig option is not of great help with that issue and is misguided and unnecessary as well. -- Stefan Richter -=====-==--- ---= -=--= http://arcgraph.de/sr/ - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
