For VL-bus many systems included 2 slots. One for a graphics card and the other for a storage controller. The VL-bus was basically a direct attachment to the 486 memory bus. Also there was Extended ISA (EISA) which was a standard promoted by PC compatible manufacturers to compete with MCA. It added 32 bit support and bus mastering to the ISA bus. I and 16 bit ISA cards would still work in an EISA slot. It never really caught on for desktops but briefly had wide support in servers.
