The file sizes are 7924 Nov 15 13:33 rose.h 110 Jul 13 16:47 rosecall.h I did a tar zxpv linux-2.0.36.tar.gz again and these two files came out exactly the same. The program did write these files to /usr/src before it terminated: 403844 Jan 7 17:05 kernel-doc-2.0.36_1.00_all.deb 293 Jan 7 16:44 kernel-source-2.0.36_1.00.dsc 7284235 Jan 7 16:44 kernel-source-2.0.36_1.00.tar.gz 7317502 Jan 7 17:04 kernel-source-2.0.36_1.00_all.deb Jan 7 17:05 linux/ I'll try it all again to see what happens. chuck
