A fella will be picking up my G4 iMac on wednesday, but I'm not 100% sure on all the preparations, so I thought I'd ask here. First of all, he probably wants to format the machine and do a fresh OS install, so how do I go about formatting my HD and reinstalling the stuff. Will it be enough to just start it up w/cd insertet after I've formatted? (I'm used to the old Windows-days where you needed a boot-disk) Second, how do I do a backup of all my mails? User > Library > Mail just seems too small in size compared to all my mails. Third, where is my keychain stored? Can't think of anything more. All help appreciated.
