Okay, if you have a system that works with 1.67 but not with 1.71, please send me the following details: a) Which module (SYSLINUX, PXELINUX, ISOLINUX) you're using; b) Which BIOS; c) What does your E820 memory information looks like (the Linux kernel will print this during early boot.) This information is vital for me to track down the bug in question. -hpa
