Erase&Install,bypassing Getting Started

Question

I only write as a last resort, my last action before insanity.  I am going to sell or give away an eMac. I have done an Erase & Install over several times to see what i have missed but the result is always the same. I want it to be completely clean but it insists that i fill in forms that create a Home Folder name and a password. This seems ridiculous when i won't be using the computer and want it to be a clean slate for new operator, i'm sure i have done this before without a problem but now i can't find how to exit the process, i have even turned it off at the power button and when turned back on its still at the same page and as i go through it insists i fill in all required information. I have pulled the main power but  still have to go over the same process around and around..
I have noticed the account it sets up for me doesn't assign Admin rights.. seems curious.
I can give the Home folder a name such as Mine and a basic password but i would prefer it to remain open. I don't know what Apple was thinking.
Am replacing 10.4 with 10.4 ( a downgraded version)
My respondents have had the answers before, i hope you do again.

Answer 1

Hello... there seems always something to worry about, even after i think i understand most of it.... i don't have any knowledge of a Zero one security so i absolutely can't answer the question... under Options offered in the installation i chose Erase & Install which says all data will be lost ( or words to that effect), i had deleted my account before doing the Erase, i have learned through forums and books to have a second ( unused) account set up with admin rights and with that account i deleted my active account.
I must have done the system installation 6 times. watching more carefully each time for anything i might have missed.
One of my books suggested ( but i don't know why) removing the disc after clicking Restart and ejecting it while the computer was black but the eject wouldn't work until the computer had restarted and anyway it carried on asking for a name and password even without the disc .
It said Registration didn't matter, obviously its old and there isn't a warranty but no way could i exit the part where it wanted a name that is then used on an automatically set up Home folder, i did see that a password was optional but without a password nothing could be done by a new user as to setting up an account with Admin rights so i went back and added one.
So ultimately the best i could do was to name the folder Home, rather than my name, and password 1234. There are no admin rights to that account but providing the next person knows the 1234 they can set up their own Admin account.
I would have preferred to set up an installation with a clean slate.
Could it depend on the type of disc used as to the options offered?
Thanks for the mention that data could still be retrieved, of course it is a concern but i didn't have anything of a particularly sensitive nature,( the **** sites are on this computer!) can't even get into my bank account without entering special grid references from a personal Netguard card.
My credit card will have been used on the computer but where possible i select for the details not to be stored.But i suppose that is no guarantee either.
I will check out the links you have sent me later.
I don't want to dump a good working computer, there is still a demand for eMacs. It is with some reluctance i will move forward from the eMac (10.5) i currently use onto an Intel mac but it must be done. Will it last as many years though, i will keep the eMac i now use as a back up but don't need to keep 2 which is why the other needs to go.
