Hello again, and thanks for your help.

Yep, that's a good solution. Unfortunatly I don't know if the CDROM is working (and have no way of knoing without and OS), besides the cdrom is SCSI and it's not easy to find one where I live.

Let's cross every bridge when we get there.

Step 1 - Boot the computer.
Is it possible to boot my performa with a bootdisk ? Where can I get it ?

After the computer is booted, it's possible to partition/format the new hardrive to hfs and copy (that 19 disks) the instalation, and instal it.

Thanks again for your help.
