BE CAREFUL! THIS CAN DESTROY YOUR HARD DISK IF DONE IMPROPERLY! usage: ldrcpy [-f] source destination Note the [-f] option to copy a file doesn't work (at least it didn't for me). I assume that would mean you could do this: # /etc/ldrcpy /usr/lib/iv/s4load.verbose /dev/rfp000 But what you need to do is to make a floppy with the type of loader you want (no verbose, or verbose) and then use the ldrcpy to copy the loader from one device to another. # /etc/ldrcpy /dev/rfp020 /dev/rfp000 By putting the verbose loader on your machine it will not autoreboot anymore without user intervention. A good use for the verbose loader is to copy the s4diag (diagnostic disk) to your hard disk and then you can boot diagnostics from the hard disk. Here's what I did: Insert Diagnostic Disk # mount /dev/fp021 /mnt # mkdir /dgn # cp /mnt/s4diag /dgn/s4diag # dismount -f Then you can boot /dgn/s4diag from the verbose loader now on the hard disk. -Lenny -- Lenny Tropiano ICUS Software Systems [w] +1 (516) 582-5525 lenny@icus.islp.ny.us Telex; 154232428 ICUS [h] +1 (516) 968-8576 {talcott,decuac,boulder,hombre,pacbell,sbcs}!icus!lenny attmail!icus!lenny ICUS Software Systems -- PO Box 1; Islip Terrace, NY 11752
