MBR & boot floppies
 
Initialize MBR
The Unix equivalent for the DOS "fdisk /mbr" is,
dd if=/dev/zero of=/dev/DEV bs=446 count=1
and in case you’re willing to remove the whole partition table with it,
dd if=/dev/zero of=/dev/DEV bs=512 count=1
Note. if may be useful to include this trick to backup the MBR and partition table.
 
On netbsd, the /mbr equilavent is,
fdisk -i wd0
 
Otherwise there’s:
- MS-SYS
- lilo
 
To fdisk /mbr from Linux, simply,
lilo -M /dev/sda
 
Build a bootable DOS floppy
To make a DOS bootable floppy on DOS,
format a: /s
and on UNIX,
fdformat /dev/fd0u1680
mformat a:
ms-sys -w /dev/fd0
mcopy /dosc/io.sys a:
mcopy /dosc/msdos.sys a:
mcopy /dosc/command.com a:
