bloodline: well he said that it took 12 secs to see the boot menu , hence if he uses whdload (HDD) then he still would have to wait 12++ secs before the machine boots after an poweroff or reboot.
anyway to the poster, try reseating the floppy cable + the power cable to the drive, if you have an hdd and accelerator then i would suggest you to remove thoose to see if its a power issue .
replacing the PSU which came with the a1200 is never a bad idea.
