Developed by VESA group that standarised the local bus on 486 PCs (though the bus can be found on some 386 and Pentium motherboards as well) in late 1992. Prior to VLB, many motherboard manufacturers had their own proprietary local buses. Vesa local bus was designed primarily for graphics adapters, but hard disk controllers were also popular. A few network interface cards also exist. The VLB 1.0 specification supports 3 cards at 25MHz, 2 cards at 33MHz and 1 card at 40MHz. 50MHz was only supported if the VGA was integrated into the motherboard. However, if both motherboard and component quality are exceptionally high, it is possible to run outside of these specs. VL-bus competed primarily with PCI, which was released around the same time. VLB was initially more popular due to lower cost, but PCI displaced it completely when Pentiums became mainstream. Later into VLBs life a V2.0 specification was released that addressed some of the limitations of V1.0, but it is unknown if any motherboards or expansion cards used it (highly unlikely). OPTi was one of the last holdovers for VLB, as you can find Pentium Socket5 motherboards equipped with the slots. VLB was very popular in 1993 and 1994, but by 1995 it began to disappear, and was all but dead by 1996.
Below is an almost complete list of SVGA adapters for VLB:
