...onto the stack, because it skipped andw 1,%xc So isolinux.bin read in "EHDD" mode by LBA and succeeded although it did not announce this capability. isohdpfd reached the "andw" instruction. So CX was set to (1 & 4) = 0 before it got pushed. So isolinux.bin read in "CHDD" mode by C/H/S and thus ran into the stack sequence bug.

...DEFAULT or UI directive in order to avoid this notification. 5) Could be more specific on the location of these files? 6) Comparing the system that "does work" to the system that "does not work", do you get a different word in the banner message? CBIOS, EBIOS, ETCD, EHDD and CHDD all indicate different disk access methods. 7) Often times, to assist diagnosing a config file search issue, I add a statement to the top of all of my config files like "SAY path/to/config.cfg" to see which config file(s) are being loaded and consider commenting it out (with a "# &q...
