Expansion
cards.
Add-in cards extend a computer with graphics, storage, capture, serial/parallel ports, accelerators, and specialized I/O. Their slot shape, electrical lane wiring, bracket, firmware, and driver support all matter.
CLASS RECORD: PCI Express and historical ISA/PCI cards. A connector's physical length does not establish its electrical lane count or device compatibility.
Reference specifications
| Bus generations | Modern PCs use PCI Express. Earlier systems used PCI, AGP, ISA, MCA, VLB, and proprietary buses; these generations are not directly interchangeable. |
|---|---|
| Lane widths | PCIe devices negotiate lane width (x1, x4, x8, x16, etc.) and generation based on device, slot wiring, firmware, and platform topology. |
| Physical details | Full-height/low-profile brackets, single/double/triple slot thickness, auxiliary power, card length, and airflow requirements vary by card. |
| Software | Firmware, operating-system drivers, DMA behavior, and application support can be as important as slot compatibility. |
Installation & catalog fields
- Record bus type, PCI IDs, subsystem vendor/device IDs, firmware, bracket type, lane width, required power, and OS support.
- Read the motherboard manual for slot wiring, lane sharing, bifurcation, and resource limitations.
- Use the proper slot cover and secure the bracket; prevent card sag, short circuits, and obstructed fans.
- Legacy cards may require option ROM support, a particular BIOS mode, or drivers for an obsolete operating system.
- Include riser cards, backplanes, M.2 adapters, storage HBAs, capture cards, serial cards, and accelerator modules in a broader index.
