HP Compaq dc7100 CMT: Impossible to enter BIOS

\015 I have an HP Compaq dc7100 CMT (P4 ?GHz, 512 MB RAM, DVD RW, DVD ROM, no HDD due to its falure) that won't let me into BIOS. If I am not quick enough to press F10, it tries to boot(http://img204.imageshack.us/my.php?image=exitinghppxeromimg2272lik4.jpg)and stops when it realizes that there is no OS (http://img132.imageshack.us/my.php?image=diskerrorimg2276lowrw1.jpg).If I do press F10 fast enough, it declares the situation (RAM, drives, errors), asks me to save the changes by pressing F1,(http://img12.imageshack.us/my.php?image=f1savechangesimg2270lowbq0.jpg)displays BIOS language choice,(http://img216.imageshack.us/my.php?image=bioslanguagesimg2265cz5.jpg)and freezes there.When I try to boot from CD (Knoppix 6.0), which was possible no more than a week ago, it doesn't go any further than the splash screen(http://img410.imageshack.us/my.php?image=knoppix6splashimg2266lozo3.jpg)and freezes again.I have tried several things:1) Attaching a floppy drive with a bootable floppy - no reaction.2) Removing all RAM to see if the system remarks it - it does. Five beeps and the screen stays off3) Disconnecting optical drives, PCI cards, network connection - nothing4) Replacing the power supply with a verified one - no change5) Clearing CMOS - nothing6) Putting a new battery even though it shouldn't make any difference, and it didn't.What I have not done was replacing the processor and the motherboard. I only have those of that class (Intel socket 775) and I would like to avoid buying one or the other unless I know which one, if either, is bad.If anyone knows or has an idea what to do, I would be extremely thankful for your input.Thanks in advance\015
