Compaq Armada 1500 Laptop Won’t Boot

I have a Compaq Armada 1500 (specifically 1575D) laptop. When I turn it on it goes from 1 to 32768 KB OK then beeps 2 times and says 162-System Options Not Set. I replaced the BIOS battery. Is the KB something with memory? I need to get into the BIOS somehow right? How would I do that (some kind of key or a floppy)?

Specs

-166 MHz Pentium MMX

-3 1/4 GB HDD IBM Travelstar

-16MB of RAM (I believe)

-CD Drive doesn’t open
