How do I make an LS-DOS double sided bootable disk?

I downloaded the LS-DOS 6.31 master from the Tim Mann page.

I used TRS-Tools to make a double sided/DD 40trk LS-DOS disk.

But, I can't find directions in any of the manuals on how to make a double sided system disk.

I'm trying to make a bootable disk for the Lo-Tech TRS-80 IDE Adapter, but the Single-Sided disk doesn't have enough room for both needed files.

(Did I mention I hate LS-DOS/L-DOS?)

Format a double sided disk in drive 1.

Backup Sys0/sys onto the disk in drive 1, this puts Sys0/sys in the right place on track 0:

BACKUP SYS0/SYS:0 :1 (S,I,Q=N)

then backup everything else to the disk in drive 1:

BACKUP :0 :1 (S,I,NEW,Q=N)

if all goes to plan you should then be able to take the disk in drive 1 and boot it in drive 0.

(I'm at work at the moment and don't have access to my reference document library, but I am pretty sure thats how I do it.)

use DISKCOPY (LS-DOS) or QFB (LDOS) to subsequently backup your newly created double-sided boot disk.
