This allows detection of memory size, devices present and 17 other useful pieces of information. Sometimes this information is 18 not present or incorrect, in which case it could lead to the machine 19 behaving incorrectly. If this happens, either disable PREP_RESIDUAL 20 or pass the 'noresidual' option to the kernel. 21 22 If you are running a PReP system, say Y here, otherwise say N. 23 24config PROC_PREPRESIDUAL 25 bool "Support for reading of PReP Residual Data in /proc" 26 depends on PREP_RESIDUAL && PROC_FS 27 help 28 Enabling this option will create a /proc/residual file which allows 29 you to get at the residual data on PReP systems. You will need a tool 30 (lsresidual) to parse it. If you aren't on a PReP system, you don't 31 want this. 32
