Last time I checked them, they were refering to Florianīs
http://www.drdos.org, which I think is the best DR-DOS
related site around at the moment.

But yes, Lineo itself do not provide any kind support to
end users. Itīs a shame.

Well, it should work, but Alain mentioned it several times,
that the DR-DOS boot partition must be the first one.

So far I never had problems booting of other primary
partitions, but it could happen that my DR-DOS partition
always was the first one. I will have to retest this
the next time I will partition a harddisk.

If it does not work, than I would consider this as being
a bug and it would require a fix - which gives a deadlock
in the current situation with stalled offical development.

In general, all you need to do is setting up the active
partition flag in the Master Boot Record (MBR). You can
do this with a disk editor, but also many FDISK utilities
will allow you to change the "active partition". (This is
what you were refering to as "assigning drive letter C:"
in the FreeDOS mailing list, which is a wrong description
of what happens at system level: it just looks so to the
user, because if the active partition is a valid DOS FAT
partition, you will boot the OS that is loaded from the
bootsector in that partition - and this DOS will assign
drive letter C: to its boot partition.) Under DR-DOS,
the other primary partitions will not be visible, while -
as I learned recently - they will be visible (at the end
of the drive letter chain) under newer issues of MS-DOS.

In case you do not want the other partitions to be visible
you can add 10h to the partition type indicator in the
MBR, that is type 06h will become 16h. Many boot managers
(including the IBM and Powerquest Boot Manager) will do
this.

Hope it helps,

 Matthias
