Oh well, > it's too late anyway. How about setting up track 1 sector 0 as a partition? I do that with every disk I own that has a boot sector implemented. Use the partion aid utility on the 1581 demo/utility disk to set up a partition 1 block long on track 1 sector 0. I believe the following command will work also: open 15,dn,15 print#15,"/0:boot sector,"+chr$(1)+chr$(0)+chr$(1)+chr$(0)+",c" close15 where dn means the drive number (usually 8 or 9) The first chr$(1) means track 1, the first chr$(0) means sector 0. The second chr$(1) and chr$(0) is the number of sectors in low byte/high byte format. (1+0*256=1) This will only work with the 1581, don't try it with the 1541/71 since I don't know what it will do on a drive with no partition features. Roger. -- Boot it up?
