I have a client that placed 4 256 memory chips in a 1.8 mhz clone pc. When he boots up the bios recognizes it but when he goes to the virtual setting in Win98 it shows a negative number. He also infor,s me that when he attemps to load some programs that he gets a memory error. The resources show only 10% free! How can that be and what may be causing the problem? Thanks!
