I had the same problem. I just edited the txtsetup.sif manually and added the missing .sys files under the [sourceDisksFiles] section. My si31xx.sys section for reference: si3124r.sys = 1,,,,,,4_,4,1,,,1,4 si3124.sys = 1,,,,,,4_,4,1,,,1,4 si3124r5.sys = 1,,,,,,4_,4,1,,,1,4 si3132r5.sys = 1,,,,,,4_,4,1,,,1,4 si3132.sys = 1,,,,,,4_,4,1,,,1,4 si3114r5.sys = 1,,,,,,4_,4,1,,,1,4 si3114r.sys = 1,,,,,,4_,4,1,,,1,4 si3112r.sys = 1,,,,,,4_,4,1,,,1,4 si3112.sys = 1,,,,,,4_,4,1,,,1,4 si3114.sys = 1,,,,,,4_,4,1,,,1,4 Check if you're missing any of those and add them to your [sourceDisksFiles] section. If you keep getting the same error with a different file, just add them manually I don't have any of those controllers, so I can't check if the drivers actually work At least the errors are gone :Edit It seems BTS DriverPacks BASE V5.10.5 fixes this problem.
