The package lodlin15.tgz available from sunsite.unc.edu
/pub/Linux/system/Bootutils. This utility
is particularly suited to boot a Umsdos system. Generally
all you need to do is
Boot DOS C:>loadlinx zimage root=D:
where zimage is a normal kernel image (compressed) simply copied
somewhere in the DOS drive.
D: is the DOS drive where you
have installed Linux.
Booting a Umsdos system from a floppy is not different from
booting a Ext2 system. You need a kernel zImage file properly
initialize to locate your root Umsdos partition. This
is generally achieved using the command
rdev. The following
sequence will initialize a zImage and put it on a floppy.
rdev zImage /dev/hda1 rdev -R zImage 0 dd if=zImage bs=8192 of=/dev/fd0
If this looks confusing, just format a boot-able DOS floppy and put the following component on it.
and setup the autoexec.bat like this
loadlinx zimage rw root=C:
LILO, the official Linux boot loader can also be used to boot a Umsdos system. I have no experience with it though. Since 1.1.60, it should work. Please email if you know something.
It can be done using any popular DOS tool. There is nothing particular about file produced by Umsdos. And Umsdos do not expect anything particular (directory layout, directory entry sequence, etc...) from the file system under it.
As far as I know, there is no Linux tool to achieve this.
Umsdos rely on the
--linux-.--- which rely on the
DOS directory. Some users may want to experiment
a bit. The utility
udosctl part of the umsdos_progs
basic directory operation (listing, deletion) independently
--linux-.--- and the DOS directory.
