Hi Peter, You've done a great job but I have some trouble on enjoying it. I tried to make a ISOLINUX CD, and followed the instructions in isolinux.doc, but dunno where shall I tell the kernel to find the root device? My isolinux.cfg contains only a "kernel bzimage" line. After I run mkisofs command, I test the .iso file on a VMware machine. ISOLINUX load the bzimage and than machine freeze. VMware report to me "guest system disable CPU" Can you give me some advice or sample? TIA _________________________________________________________ Do You Yahoo!?
