Intermitent CDROM operation – early W95

486 w/8MB fails CD read of HP printer install. But previously loaded MPC CD program recognizes D: and works normally. CD is fine in other machines. Device shows under CP|system as Sony with two installs at differing addresses. It plays audio CD’s through program which came with Creative SB16 card. On a friend’s machine and of course the OS install CD/disks are gone.
