VL-bus(VESA Local-BUS) A peripheral bus from VESA that was primarily used in computers with 486 CPUs. VL-bus provided a high-speed data path between the CPU and peripherals (video, disk, etc.). It was a 32-bit bus that supported bus mastering and ran at speeds up to 40 MHz. With up to three VL-bus slots on the motherboard, each slot was in two parts: one Micro Channel slot along with an ISA, EISA or a second Micro Channel slot. See PC data buses.
|The VL-bus was widely used on 486 motherboards, providing a wider bandwidth for peripheral data transfer than the traditional ISA bus.|
