Help with my Pack Mate 6419CD.

Is it possible to locate, and pull out the CMOS chip? I understand that after pulling this out, and putting it right back in, all passwords will be ereased, and I will be able to access this ancient machine, and boot it up. Can anyone shed some light on this? I cannot get past the password screen to get into this computer, It was given to me. I want to try to boot this up and install win95. I have an Intel 486DX processor,(66MHz),420MB HD, 4MB of ram upgradable to 64. 16 bit, 1MB video memory. Which is all nota if I can’t figure out how to start this darn thing.HELP PLEASE.
