I have a direcTIVO R10 a.k.a. RCA DVR80

Got it off of ebay *WORKS!* yeah right.. when i got it. it booted and loaded tivo but thats all.. "clear and erase all" asked for a parental code i didn't have, so i took the drive out of it partitioned and formatted it, the hard drive seems to be in working order but my instantcake cd wouldnt work in my desktop tower.. keyboard wasnt detected (tried 3 differnt keyboards.. vmlinux mustn't like the tower) took an old 333mhz tower from my basement keyboard was found instacake said it was succesfull but the motherboard didnt have the "missing pin" in the ide socket. so i removed it so my ide cable would work.. the hdd is still way too big for the old bios to detect it.. but instacake seems to find it alright. instacake restores the image and says it was successful but my tivo just reboots after maybe a minute or two.. so i went back to istacake and bought 6.2a and it does the same thing.. now before i break down and buy a hdd from weaknees i want to make sure i didnt miss something. or if i do buy new hdd if it will even work
