Eight more data lines, bringing the data bus to 16 bits in width.
Four more address lines, bringing the address bus to 24 bits in width.
Four more DMA channels, 4 through 7.
Five more IRQ levels: IRQ 10, 11, 12, 14, and 15.
These two-slot connectors are called 16-bit slots. You can see these rivo kinds of connectors in Figure 6.1.
For a while, this 16-hit bus was called the AT bus. Since 1988, however, most people have referred to these types of bus slots as Industry Standard Architecture, or ISA, slots. You can tell the difference between an 8-bit and a 16-bit ISA board by looking at the edge connector on the bottom of it (Fig. 6.1).
