========================================
Problem:
Installing the multiple boot loader on the primary drive (ad0, Win98), the kernel doesn't load, the active partition flag become set down; after a generation of a new freebsd partition on drive HD 4GB (ad3) -> with an incorrect geometry <-, the boot loader damaged the partition tables of the 10GB drive (ad0) and of the 20 gb drive (ad2, Linux). The 10 Gb drive /dev/ad0 crash totally with need to fix the partition table, the boot sector and to format, with all data lost.
