Thank you. For FreeBSD, it should be like=20 >=20 > % dd if=3D/dev/ad0s1 of=3D/tmp/dos_fat16.dd bs=3D512 count=3D1 > % dd if=3D/dev/ad0s1 of=3D/tmp/dos_fat32.dd bs=3D512 count=3D3 >=20 > BTW about FreeDOS: how many sectors for its bootblock must I copy? > I did not know that fat16 and fat32 VBRs had different size (1 sector > vs 3 sectors). Hmm, I'd try with the same numbers. Since mbrbm works equally with both m$-dos and FreeDOS, I guess that beginning sectors are composed the same way. Apart from install CDs, the only bootable image that FreeDOS-1.0 actually offers for download is 1.4M fdboot.img: http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.0/ Otherwise, I don't see any other way to obtain sectors of the full system but to actually install FreeDOS somewhere (on virtual machine or on a real slice).
