If disk is `dangerously dedicated', sector 0:0:1 is occupied with boot1, which does not use master PT area (0x1BE-0x1FF) and even contains a simple fake valid PT. Did you ever try to set there something syntactically valid for your BIOS and enough to allow loading of specific "bootloader"? If you did, what was the problem? P.S. On our FreeBSD hosts bunch we almost proved practically that the only safe partitioning is to create DOS slices (with below-cyl-1024 bootable one) with LBA geometry specified to fdisk. Any another approach leads to something strange effects: e.g. BTX cannot load /boot/loader and loads kernel directly, with natural `nlist failed'. But we never tried to change fake PT on dedicated disk directly. /netch To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
