hi TC! i actually exprimented on boot.bin & boot.img over the weekend ... with these files (and/or) in HFTOOLS folder ... no ISO was created ... no wonder the cmd file finished faster ... but when i took those 2 out with bbie & mkisofs still in HFTOOLS & leaving the original source CD in the drive, boot.bin was recreated & ISO was created as well ... as for the presence of the boot.bin there, i have never removed since i 1st used HFSLIP ... i got curious because of the posts i read prior to taking my days-off from work oh btw, this was using 60803 ... i'll ask related questions in the appropriate thread: ISO creation fails with 60803
