I dont remember, but I didn't think F1 was it. To find out, go to the HP/Comcrap website and look up your machine.
Now, many comax I've seen, have the bios program somehow on a special hidden partition on the hard drive. This means that if someone has either replaced the drive, OR completely removed the existing partitions and re-installed a system, that bios stuff will not be there, and you WILL NOT be able to enter the bios.
Never fear, though, you can download a floppy(s) off the comaack website that will take the place of the hdd stuff.
I'm not sure, but I imagine that the startup logo is somewhere in this same deal. (I try to stay away from these things.)
