username/password not accepted

[yellowdog-newbie@lists.terrasoftsolutions.com]

formatted with Drive Setup
single, 20gig drive, 1gig, 256meg, balance for ydl
running os9.2.1 on old world g3 tower with 448meg ram

after install, attempt to boot into ydl, username/password are invalid

I wiped everything, wrote username/password ahead of time, installed, 
and copied username/password into install. same problem.

fyi - i am a support tech for a data integration software company, i 
did the step-by-step on this and failed.

any tips?
