thanks. It does power on and I here the chime, followed by the mac folder with question mark. yeah. Unless the apple disks you mentioned are free I'll have to go the ubunto or yellow dog route. Since the chime tells me all is well with the main components (memory, processor, system board, I assume) I just need to verify the ATA controller works and thus a new hard drive will work, before spending money. For that I was originally looking for the mac equivelent of verifying that the drive I plugged in was 'recognized' by the BIOS (a pc term). If it did, I would go ahead and buy OS X. So I just learned mac's BIOS equivalent, so to speak, is OpenFirmware, but its command shell based and I don't know the commands to do this, if there is any. Although more time consuming, obtaining and booting from an ubunto or other linux distro and verifiying it 'sees' the test hard drive will accomplish what I need as well.
thanks, I appreciate it.
