WolfPackPBX

while installing wolfpack on older machine (generic tower) 2 40g western
digital hdd 256mb ram 800MHz. during install(ISO) when password option came
up (NOOB!)when trying to enter password cursor would drop from top to
confirm field at first keystroke. Made several attempts same problem(only
one time did this not happen:hitting space bar [tab] space bar) at any rate
I am unable to log into system at any level. Am at this point completing
memory test(looks as if it will pass). Is there any way to log into wolf
pack or CentOS4 without or by resetting pass? If I run ISO again will it
overwrite and if so will same problem occur? Need help desperately, no
experience with command line. Am trying to read up on commands at this
point but to much info to absorb in short time span. Please assist.
Respectfully,
Jerry
