Industry Standard Architecture
The bus mastering support is also enhanced to provide access to 4 GB of memory. It was somewhat expensive to implement though not as much as MCA , so it never became particularly popular in desktop PCs. However, it was reasonably successful in the server market,  as it was better suited to bandwidth-intensive tasks such as disk access and networking. The bit slots were a superset of the 8-bit configuration, so most 8-bit cards were able to plug into a bit slot some cards used a "skirt" design that physically interfered with the extended portion of the slot and continue to run in 8-bit mode.
One of the key reasons for the success of the IBM PC and the PC clones that followed it was the active ecosystem of third-party expansion cards available for the machines. IBM was restricted from patenting the bus, and widely published the bus specifications. As the PC-clone industry continued to build momentum in the mid- to lates, several problems with the bus began to be apparent.
First, because the "AT slot" as it was known at the time was not managed by any central standards group, there was nothing to prevent a manufacturer from "pushing" the standard. One of the most common issues was that as PC clones became more common, PC manufacturers began ratcheting up the processor speed to maintain a competitive advantage. Most PC makers eventually decoupled the slot clock from the system clock, but there was still no standards body to "police" the industry.
As companies like Dell modified the AT bus design,  the architecture was so well entrenched that no single clone manufacturer had the leverage to create a standardized alternative, and there was no compelling reason for them to cooperate on a new standard. Because of this, when the first -based system the Compaq Deskpro hit the market in , it still supported bit slots. Meanwhile, IBM began to worry that it was losing control of the industry it had created.

The need for faster graphics was being driven by increasing adoption of graphical user interfaces in PC operating systems. While IBM's attempt at producing a successor to ISA with the Micro Channel Architecture was a technically viable option, it failed in the market due to its proprietary nature and imposition of licensing fees. However, as these manufacturer-specific solutions were not standardized, there were no provisions for providing interoperability between them.
As such, one requirement for VLB to gain industry adoption was that it had to be a minimal burden for manufactures to implement, in terms of board re-design and component costs; otherwise, manufacturers would not have been convinced to change from their own proprietary solutions. As VLB fundamentally tied a card directly to the processor bus with minimal intermediary logic reducing logic design and component costs , timing and arbitration duties were strongly dependent on the cards and CPU.
This simplicity of VLB unfortunately created several factors that served to limit its useful life substantially:.
VLB importantly offered a less costly high speed interface for consumer systems, as only by was PCI commonly available outside of the server market via the Pentium and Intel's chipsets.

Initial line-up of the commercially available M. Components may be mounted on either side of the module, with the actual module type limiting how thick the components can be; the maximum allowable thickness of components is 1. Different host-side connectors are used for single- and double-sided M. PCB of an M. Similar keying applies to M. Various types of M. The "HH" part specifies, in an encoded form, whether a module is single- or double-sided, and the maximum allowed thickness of mounted components; possible values are listed in the right table above.
Module keying is specified by the "K-K" part, in an encoded form using the key IDs from the left table above; it can also be specified as "K" only, if a module has only one keying notch.
