Uh, I did just that (blew away my dual-boot FreeBSD/Win2K boot
sector by reinstalling win2k after being an Uber-Idiot), which is how I
painfully discovered the lack of pointers to boot0cfg.
[ I actually hex dumped the boot sector, read the boot0 asm code, and
binary-edited the boot sector to enable LBA, before I discovered the
existence of boot0cfg, which would have made my life MUCH easier ....
;-( ]
The easiest solution is to boot the live filesystem CDROM (you did
*buy* the four-disk set, right?), use fdisk to restore the boot sector,
and then run boot0cfg. Everything you need is on the bootable live
filesystem CDROM. Just make sure you use /boot/boot0 as the boot
sector, and not /boot/mbr (the default).
